Alarm | SteelHead state | Reason |
Admission Control | Admission Control | • Connection Limit—Indicates that the system connection limit has been reached. Additional connections are passed through unoptimized. The alarm clears when the SteelHead moves out of this condition. • CPU—Indicates that the SteelHead has entered admission control due to high CPU use. During this event, the SteelHead continues to optimize existing connections, but passes through new connections without optimization. The alarm automatically clears when the CPU usage decreases. • MAPI—Indicates that the total number of MAPI optimized connections has exceeded the maximum admission control threshold. By default, the maximum admission control threshold is 85 percent of the total maximum optimized connection count for the client-side SteelHead. The SteelHead reserves the remaining 15 percent so the MAPI admission control doesn’t affect the other protocols. The 85 percent threshold is applied only to MAPI connections. The alarm automatically clears when the MAPI traffic decreases; however, it can take one minute for the alarm to clear. The system preemptively closes MAPI sessions to reduce the connection count in an attempt to bring the SteelHead out of admission control. RiOS closes MAPI sessions in this order: – MAPI prepopulation connections – MAPI sessions with the largest number of connections – MAPI sessions with the most idle connections – Most recently optimized MAPI sessions or the oldest MAPI session – MAPI sessions exceeding the memory threshold • Memory—Indicates that the appliance has entered admission control due to memory consumption. The appliance is optimizing traffic beyond its rated capability and is unable to handle the amount of traffic passing through the WAN link. During this event, the appliance continues to optimize existing connections, but new connections are passed through without optimization. No other action is necessary as the alarm automatically clears when the traffic decreases. • TCP—Indicates that the appliance has entered admission control due to high TCP memory use. During this event, the appliance continues to optimize existing connections, but new connections are passed through without optimization. The alarm automatically clears when the TCP memory pressure decreases. |
Asymmetric Routing | Needs Attention | Indicates that the system is experiencing asymmetric traffic. Indicates OK if the system isn’t experiencing asymmetric traffic. In addition, any asymmetric traffic is passed through, and the route appears in the Asymmetric Routing table. For details about the Asymmetric Routing table, see
Configuring asymmetric routing features. |
Connection Forwarding | Degraded | Indicates that the system has detected a problem with a connection-forwarding neighbor. The connection-forwarding alarms are inclusive of all connection-forwarding neighbors. For example, if a SteelHead has three neighbors, the alarm triggers if any one of the neighbors is in error. In the same way, the alarm clears only when all three neighbors are no longer in error. • Cluster Neighbor Incompatible—Indicates that a connection-forwarding neighbor in a SteelHead Interceptor cluster has path selection enabled while path selection isn’t enabled on another appliance in the cluster. This alarm can also indicate that a connection-forwarding neighbor is running a RiOS version that is incompatible with IPv6. Neighbors must be running RiOS 8.5 or later. The SteelHead neighbors pass through IPv6 connections when this incompatibility is detected. • Multiple Interface—Indicates that the connection to an appliance in a connection forwarding cluster has been lost or disconnected due to a configuration incompatibility. • Single Interface—Indicates that the connection to a SteelHead connection-forwarding neighbor is lost. These issues trigger the single connection-forwarding alarm: – The connection-forwarding neighbor has not sent a keepalive message within the time-out period to the neighbor SteelHead(s), indicating that the connection has been lost. – The connection can’t be established with a connection-forwarding neighbor. – The connection has been closed by the connection-forwarding neighbor. – The connection has been lost with the connection-forwarding neighbor due to an error. – The connection has been lost because requests have not been acknowledged by a connection-forwarding neighbor within the set threshold. – The SteelHead has timed out while waiting for an initialization message from a connection-forwarding neighbor. – The amount of latency between connection-forwarding neighbors has exceeded the specified threshold. |
CPU Utilization | Degraded | Indicates that the system has reached the CPU threshold for any of the CPUs in the SteelHead. If the system has reached the CPU threshold, check your settings. For details, see
Configuring alarm settings. If your alarm thresholds are correct, reboot the SteelHead. For details, see
Rebooting and shutting down the SteelHead. Note: If more than 100 MB of data is moved through a SteelHead while performing PFS synchronization, the CPU utilization might become high and result in a CPU alarm. This CPU alarm isn’t cause for concern. |
Data Store | Critical | • Corruption—Indicates that the RiOS data store is corrupt or has become incompatible with the current configuration. • Data Store Clean Required—Indicates that you must clear the RiOS data store. To clear the data store, choose Administration > Maintenance: Services and select the Clear Data Store check box before restarting the appliance. Clearing the data store degrades performance until the system repopulates the data. • Encryption Level Mismatch—Indicates a RiOS data store error such as an encryption, header, or format error. • Synchronization Error—Indicates that the RiOS data store synchronization between two SteelHeads has been disrupted and the RiOS data stores are no longer synchronized. For details, see
Synchronizing peer RiOS data stores. Resetting the Data Store alarm If a data store alarm was caused by an unintended change to the configuration, you can change the configuration to match the previous RiOS data store settings, and then restart the service without clearing the data store to reset the alarm. Typical configuration changes that require a restart with a clear RiOS data store are enabling the extended peer table or changing the data store encryption type. For details, see
Configuring peering and
Encrypting the RiOS data store. To clear the RiOS data store of data, choose Administration > Maintenance: Services, select Clear Data Store and click Reboot to reboot the optimization service. For details, see
Starting and stopping the optimization service. |
Disk Full | Indicates that the system partitions (not the RiOS data store) are full or almost full. For example, RiOS monitors the available space on /var, which is used to hold logs, statistics, system dumps, TCP dumps, and so on. Examine the directory to see if it is storing an excessive amount of snapshots, system dumps, or TCP dumps that you could delete. You could also delete any RiOS images that you no longer use. | |
Domain Authentication Alert | Needs Attention | Indicates that the system is unable to communicate with the DC, has detected an SMB signing error, or delegation has failed. CIFS-signed and Encrypted-MAPI traffic is passed through without optimization. For details, see
Configuring CIFS optimization. |
Domain Join Error | Degraded | Indicates an attempt to join a Windows domain has failed. For details, see
Troubleshooting a domain join failure. |
Flash Protection Failure | Critical | Indicates that the USB flash drive has not been backed up because there isn’t enough available space in the /var filesystem directory. Examine the /var directory to see if it is storing an excessive amount of snapshots, system dumps, or TCP dumps that you could delete. You could also delete any RiOS images that you no longer use. |
Hardware | Either Critical or Degraded, depending on the state | • Disk Error—Indicates that one or more disks is offline. To see which disk is offline, enter this CLI command from the system prompt: show raid diagram • Fan Error—Indicates that a fan is failing or has failed and must be replaced. • Flash Error—Indicates an error with the flash drive hardware. At times, the USB flash drive that holds the system images might become unresponsive; the SteelHead continues to function normally. When this error triggers you can’t perform a software upgrade, as the SteelHead is unable to write a new upgrade image to the flash drive without first power cycling the system. To reboot the appliance, go to the Administration > Maintenance: Reboot/Shutdown page or enter the CLI reload command to automatically power cycle the SteelHead and restore the flash drive to its proper function. On desktop SteelHead x50 and x55 models, you must physically power cycle the appliance (push the power button or pull the power cord). • IPMI—Indicates an Intelligent Platform Management Interface (IPMI) event (not supported on all appliance models). This alarm triggers when there has been a physical security intrusion. These events trigger this alarm: – chassis intrusion (physical opening and closing of the appliance case) – memory errors (correctable or uncorrectable ECC memory errors) – hard drive faults or predictive failures – power supply status or predictive failure By default, this alarm is enabled. • Management Disk Size Error—Indicates that the size of the management disk is too small for the SteelHead (Virtual Edition) model. This condition can occur when upgrading a SteelHead (Virtual Edition) to a VCX model without first expanding the management disk to a size that supports the higher end models. To clear the alarm, increase the size of the management disk. • Memory Error—Indicates a memory error (for example, when a system memory stick fails). |
• Other Hardware Error—Indicates one of these hardware issues: – the SteelHead doesn’t have enough disk, memory, CPU cores, or NIC cards to support the current configuration. – the SteelHead is using a memory Dual In-line Memory Module (DIMM), a hard disk, or a NIC that isn’t qualified by Riverbed. • DIMMs are plugged into the SteelHead but RiOS can’t recognize them because: – a DIMM is in the wrong slot. You must plug DIMMs into the black slots first and then use the blue slots when all of the black slots are in use. —or— – a DIMM is broken and you must replace it. – other hardware issues exist. By default, this alarm is enabled. • Safety Valve: disk access exceeds response times—Indicates that the SteelHead is experiencing increased disk access time and has started the safety valve disk bypass mechanism that switches connections into SDR-A. SDR-A performs data reduction in memory until the disk access latency falls below the safety valve activation threshold. Disk access time can exceed the safety valve activation threshold for several reasons: the SteelHead might be undersized for the amount of traffic it is required to optimize, a larger than usual amount of traffic is being optimized temporarily, or a disk is experiencing hardware issues such as sector errors, failing mechanicals, or RAID disk rebuilding. You configure the safety valve activation threshold and timeout using CLI commands: datastore safety-valve threshold datastore safety-value timeout For details, see the Riverbed Command-Line Interface Reference Manual. To clear the alarm, restart the SteelHead. • Power Supply—Indicates an inserted power supply cord doesn’t have power, as opposed to a power supply slot with no power supply cord inserted. • RAID—Indicates an error with the RAID array (for example, missing drives, pulled drives, drive failures, and drive rebuilds). An audible alarm might also sound. To see if a disk has failed, enter this CLI command from the system prompt: show raid diagram For drive rebuilds, if a drive is removed and then reinserted, the alarm continues to be triggered until the rebuild is complete. Rebuilding a disk drive can take 4-6 hours. | ||
Inbound QoS WAN Bandwidth Configuration | Degraded (Needs Attention) | Indicates that the inbound QoS WAN bandwidth for one or more of the interfaces is set incorrectly. You must configure the WAN bandwidth to be less than or equal to the interface bandwidth link rate. This alarm triggers when the system encounters one of these conditions: • An interface is connected and the WAN bandwidth is set higher than its bandwidth link rate: for example, if the bandwidth link rate is 1536 kbps, and the WAN bandwidth is set to 2000 kbps. • A nonzero WAN bandwidth is set and QoS is enabled on an interface that is disconnected; that is, the bandwidth link rate is 0. • A previously disconnected interface is reconnected, and its previously configured WAN bandwidth was set higher than the bandwidth link rate. The Management Console refreshes the alarm message to inform you that the configured WAN bandwidth is set higher than the interface bandwidth link rate. While this alarm appears, the SteelHead puts existing connections into the default class. The alarm clears when you configure the WAN bandwidth to be less than or equal to the bandwidth link rate or reconnect an interface configured with the correct WAN bandwidth. By default, this alarm is enabled. |
Licensing | Needs Attention, Degraded, or Critical, depending on the state | Indicates whether your licenses are current. • Appliance Unlicensed—This alarm triggers if the SteelHead a license installed for its currently configured model or feature set. For details about updating licenses, see
Managing licenses and model upgrades. • Autolicense Critical Event—This alarm triggers on a SteelHead (Virtual Edition) appliance when the Riverbed Licensing Portal can’t respond to a license request with valid licenses. The Licensing Portal can’t issue a valid license for one of these reasons: – A newer SteelHead (Virtual Edition) appliance is already using the token, so you can’t use it on the SteelHead (Virtual Edition) appliance displaying the critical alarm. Every time the SteelHead (Virtual Edition) appliance attempts to refetch a license token, the alarm retriggers. – The token has been redeemed too many times. Every time the SteelHead (Virtual Edition) appliance attempts to refetch a license token, the alarm retriggers. Discontinue use of the other SteelHead (Virtual Edition) appliance or contact Support. • Autolicense Informational Event—This alarm triggers if the Riverbed Licensing Portal has information regarding the licenses for a SteelHead (Virtual Edition) appliance. For example, the SteelHead (Virtual Edition) appliance displays this alarm when the portal returns licenses that are associated with a token that has been used on a different SteelHead (Virtual Edition) appliance. Make sure that any previous SteelHead (Virtual Edition) appliances that were licensed with that token are no longer running. The alarm automatically clears the next time the SteelHead (Virtual Edition) appliance fetches the licenses from the Licensing Portal. • Licenses Expired—This alarm triggers if one or more features has at least one license installed, but all of them are expired. • Licenses Expiring—This alarm triggers if the license for one or more features is going to expire within two weeks. The licenses expiring and licenses expired alarms are triggered per feature. For example, if you install two license keys for a feature, LK1-FOO-xxx (expired) and LK1-FOO-yyy (not expired), the alarms don’t trigger, because the feature has one valid license. If the Licenses Expiring alarm triggers, the system status changes to Needs Attention. The Licenses Expired alarm changes the system status to Degraded. Depending on the expiring license, other alarms might trigger simultaneously. For example, if the primary license expires, the Appliance Unlicensed alarm triggers and changes the health to Critical. |
Link Duplex | Degraded | Indicates that an interface was not configured for half-duplex negotiation but has negotiated half-duplex mode. Half-duplex significantly limits the optimization service results. The alarm displays which interface is triggering the duplex error. Choose Networking > Networking: Base Interfaces and examine the SteelHead link configuration. Next, examine the peer switch user interface to check its link configuration. If the configuration on one side is different from the other, traffic is sent at different rates on each side, causing many collisions. To troubleshoot, change both interfaces to automatic duplex negotiation. If the interfaces don’t support automatic duplex, configure both ends for full duplex. You can enable or disable the alarm for a specific interface. To disable an alarm, choose Administration: System Settings > Alarms and select or clear the check box next to the link alarm. |
Link I/O Errors | Degraded | Indicates that the error rate on an interface has exceeded 0.1 percent while either sending or receiving packets. This threshold is based on the observation that even a small link error rate reduces TCP throughput significantly. A properly configured LAN connection experiences few errors. The alarm clears when the error rate drops below 0.05 percent. You can change the default alarm thresholds by entering the alarm link_io_errors err-threshold <threshold-value> CLI command at the system prompt. For details, see the Riverbed Command-Line Interface Reference Manual. To troubleshoot, try a new cable and a different switch port. Another possible cause is electromagnetic noise nearby. You can enable or disable the alarm for a specific interface. For example, you can disable the alarm for a link after deciding to tolerate the errors. To enable or disable an alarm, choose Administration > System Settings: Alarms and select or clear the check box next to the link name. |
Link State | Degraded | Indicates that the system has lost one of its Ethernet links due to an unplugged cable or dead switch port. Check the physical connectivity between the SteelHead and its neighbor device. Investigate this alarm as soon as possible. Depending on what link is down, the system might no longer be optimizing, and a network outage could occur. You can enable or disable the alarm for a specific interface. To enable or disable the alarm, choose Administration > System Settings: Alarms and select or clear the check box next to the link name. |
Memory Error | Degraded | Indicates that the system has detected a memory error. A system memory stick might be failing. First, try reseating the memory first. If the problem persists, contact Support for an RMA replacement as soon as practically possible. |
Memory Paging | Degraded | Indicates that the system has reached the memory paging threshold. If 100 pages are swapped approximately every two hours the SteelHead is functioning properly. If thousands of pages are swapped every few minutes, reboot the SteelHead. For details, see
Rebooting and shutting down the SteelHead. If rebooting doesn’t solve the problem, contact Support at
https://support.riverbed.com. |
Neighbor Incompatibility | Degraded | Indicates that the system has encountered an error in reaching a SteelHead configured for connection forwarding. For details, see
Configuring connection forwarding features. |
Network Bypass | Critical | Indicates that the system is in bypass failover mode. If the SteelHead is in bypass failover mode, restart the optimization service. If restarting the service doesn’t resolve the problem, reboot the SteelHead. If rebooting doesn’t resolve the problem, shut down and restart the SteelHead. For details, see
Rebooting and shutting down the SteelHead, and
Starting and stopping the optimization service. |
NFS V2/V4 Alarm | Degraded | Indicates that the system has detected either NFSv2 or NFSv4 is in use. The SteelHead supports only NFSv3 and passes through all other versions. For details, see
Configuring NFS optimization. |
Optimization Service | Critical | • Internal Error—The optimization service has encountered a condition that might degrade optimization performance. Go to the Administration > Maintenance: Services page and restart the optimization service. • Unexpected Halt—The optimization service has halted due to a serious software error. See if a system dump was created. If so, retrieve the system dump and contact Support immediately. For details, see
Viewing logs. • Service Status—The optimization service has encountered an optimization service condition. The message indicates the reason for the condition: – optimization service is not running This message appears after an optimization restart. For more information, review the SteelHead logs. – in-path optimization is not enabled This message appears if an in-path setting is disabled for an in-path SteelHead. For more information, review the SteelHead logs. – optimization service is initializing This message appears after a reboot. The alarm clears. For more information, review the SteelHead logs. – optimization service is not optimizing This message appears after a system crash. For more information, review the SteelHead logs. – optimization service is disabled by user This message appears after entering the CLI command no service enable or shutting down the optimization service from the Management Console. For more information, review the SteelHead logs. – optimization service is restarted by user This message appears after the optimization service is restarted from either the CLI or Management Console. You might want to review the SteelHead logs for more information. |
Outbound QoS WAN Bandwidth Configuration | Degraded (Needs Attention) | Indicates that the outbound QoS WAN bandwidth for one or more of the interfaces is set incorrectly. You must configure the WAN bandwidth to be less than or equal to the interface bandwidth link rate. This alarm triggers when the system encounters one of these conditions: • An interface is connected and the WAN bandwidth is set higher than its bandwidth link rate: for example, if the bandwidth link rate is 1536 kbps, and the WAN bandwidth is set to 2000 kbps. • A nonzero WAN bandwidth is set and QoS is enabled on an interface that is disconnected; that is, the bandwidth link rate is 0. • A previously disconnected interface is reconnected, and its previously configured WAN bandwidth was set higher than the bandwidth link rate. The Management Console refreshes the alarm message to inform you that the configured WAN bandwidth is set higher than the interface bandwidth link rate. While this alarm appears, the SteelHead puts existing connections into the default class. The alarm clears when you configure the WAN bandwidth to be less than or equal to the bandwidth link rate or reconnect an interface configured with the correct WAN bandwidth. By default, this alarm is enabled. |
Path Selection Path Down | Degraded | Indicates that one of the predefined paths for a connection is unavailable because it has exceeded either the timeout value for path latency or the threshold for observed packet loss. When a path fails, the SteelHead directs traffic through another available path. When the original path comes back up, the SteelHead redirects the traffic back to it. |
Path Selection Path Probing Error | Degraded | Indicates that a path selection monitoring probe for a predefined path has received a probe response from an unexpected relay or interface. |
Process Dump Creation Error | Degraded | Indicates that the system has detected an error while trying to create a process dump. This alarm indicates an abnormal condition in which RiOS can’t collect the core file after three retries. It can be caused when the /var directory, which is used to hold system dumps, is reaching capacity or other conditions. When this alarm is raised, the directory is blacklisted. Contact Support to correct the issue. |
Proxy File Service | Degraded | Indicates that there has been a PFS operation or configuration error. • Proxy File Service Configuration—Indicates that a configuration attempt has failed. If the system detects a configuration failure, attempt the configuration again. • Proxy File Service Operation—Indicates that a synchronization operation has failed. If the system detects an operation failure, attempt the operation again. |
Secure Transport | Indicates that a peer SteelHead has encountered a problem with the secure transport controller connection. The secure transport controller is a SteelHead that typically resides in the data center and manages the control channel and operations required for secure transport between SteelHead peers. The control channel between the SteelHeads uses SSL to secure the connection between the peer SteelHead and the secure transport controller. • Connection with Controller Lost—Indicates that the peer SteelHead is no longer connected to the secure transport controller for one of these reasons: – The connectivity between the peer SteelHead and the secure transport controller is lost. – The SSL for the connection isn’t configured correctly. • Registration with Controller Unsuccessful—Indicates that the peer SteelHead isn’t registered with the secure transport controller, and the controller doesn’t recognize it as a member of the secure transport group. | |
Secure Vault | Degraded | Indicates a problem with the secure vault. • Secure Vault Locked—Needs Attention. Indicates that the secure vault is locked. To optimize SSL connections or to use RiOS data store encryption, the secure vault must be unlocked. Choose Administration > Security: Secure Vault and unlock the secure vault. • Secure Vault New Password Recommended—Degraded. Indicates that the secure vault requires a new, nondefault password. Reenter the password. • Secure Vault Not Initialized—Critical. Indicates that an error has occurred while initializing the secure vault. When the vault is locked, SSL traffic isn’t optimized and you can’t encrypt the RiOS data store. For details, see
Unlocking the secure vault. |
Software Compatibility | Needs Attention or Degraded, depending on the state | Indicates that there’s a mismatch between software versions in the Riverbed system. • Peer Mismatch—Needs Attention. Indicates that the appliance has encountered another appliance that is running an incompatible version of system software. Refer to the CLI, Management Console, or the SNMP peer table to determine which appliance is causing the conflict. Connections with that peer will not be optimized, connections with other peers running compatible RiOS versions are unaffected. To resolve the problem, upgrade your system software. No other action is required as the alarm automatically clears. • Software Version Mismatch—Degraded. Indicates that the appliance is running an incompatible version of system software. To resolve the problem, upgrade your system software. No other action is required as the alarm automatically clears. By default, this alarm is enabled. |
SSD Write Cycle Level Exceeded | Degraded | Indicates that the accumulated Solid-State Disk (SSD) write cycles are exceeding a predefined write cycle level (95 percent) on SteelHead models with SSDs. If the alarm triggers, the administrator can swap out the disk before any problems arise. RiOS tracks the number of writes to each block. To view the associated statistics, enter this CLI command: show stats alarm ssd_wear_warning For details, see the Riverbed Command-Line Interface Reference Manual. |
SSL | Needs Attention | Indicates that an error has been detected in your secure vault or SSL configuration. For details about checking your settings, see
Verifying SSL and secure inner channel optimization. • Non-443 SSL Servers—Indicates that during a RiOS upgrade (for example, from 8.5 to 9.0), the system has detected a preexisting SSL server certificate configuration on a port other than the default SSL port 443. SSL traffic might not be optimized. To restore SSL optimization, you can add an in-path rule to the client-side SteelHead to intercept the connection and optimize the SSL traffic on the nondefault SSL server port. After adding an in-path rule, you must clear this alarm manually by entering this CLI command: stats alarm non_443_ssl_servers_detected_on_upgrade clear • SSL Certificates Error—Indicates that an SSL peering certificate has failed to re-enroll automatically within the Simple Certificate Enrollment Protocol (SCEP) polling interval. • SSL Certificates Expiring—Indicates that an SSL certificate is about to expire. Two types of certificates can trigger this alarm: Certificate Authority certificates used to validate servers and SSL Server Certificates that the SteelHead uses when acting as a trusted man in the middle. Depending on the type of certificate, you can review the expiring certificates on the Optimization: SSL > Certificate Authorities page or the Optimization: SSL > SSL Main Settings page. (The alarm only redirects you to the Certificate Authorities page, but you might need to review the SSL Main Settings page for your certificate.) Note, certificates are sorted by name and the expiring certificates might not be visible until you scroll through the list. • SSL Certificates SCEP—Indicates that an SSL certificate has failed to reenroll automatically within the SCEP polling interval. • SSL HSM private key not accessible—Indicates that the server-side SteelHead can’t import the private key corresponding to the proxy certificate from a SafeNet Luna Hardware Security Module (HSM) server. The private key is necessary to establish mutual trust between the SteelHead and the HSM for proxied SSL traffic optimization. Check that the server-side SteelHead can access the HSM device and that the private key exists on the HSM server. For details, see the Riverbed Command-Line Interface Reference Manual. |
Storage Profile Switch Failed | Either Critical or Needs Attention, depending on the state | On a SteelHead EX, indicates that an error has occurred while repartitioning the disk drives during a storage profile switch. The repartitioning was unsuccessful. A profile switch changes the disk space allocation on the drives to allow VE and VSP to use varying amounts of storage. It also clears the SteelFusion and VSP data stores, and repartitions the data stores to the appropriate sizes. You switch a storage profile by entering the disk-config layout CLI command at the system prompt or by choosing Administration > System Settings: Disk Management on an EX or EX+SteelFusion SteelHead and selecting a storage profile. A storage profile switch requires a reboot of the SteelHead. The alarm appears after the reboot. These reasons can cause a profile switch to fail: • RiOS can’t validate the profile. • The profile contains an invalid upgrade or downgrade. • RiOS can’t clean up the existing VDMKs. During cleanup, RiOS uninstalls all slots and deletes all backups and packages. When you encounter this error, reboot the SteelHead and then switch the storage profile again. If the switch succeeds, the error clears. If it fails, RiOS reverts the SteelHead to the previous storage profile. • If RiOS successfully reverts the SteelHead to the previous storage profile, the alarm status displays needs attention. • If RiOS is unable to revert the SteelHead to the previous storage profile, the alarm status becomes critical. For assistance, contact Support: https://support.riverbed.com |
System Detail Report | Degraded | Indicates that the system has detected a problem with an optimization or system module. For details, see
Viewing System Details reports. |
Temperature | Critical or Warning | • Critical—Indicates that the CPU temperature has exceeded the critical threshold. The default value for the rising threshold temperature is 80°C; the default reset threshold temperature is 67°C. • Warning—Indicates that the CPU temperature is about to exceed the critical threshold. |
Web Proxy | Degraded | • Configuration—Indicates that the system has detected an error with the web proxy configuration. • Service Status—Indicates that the system has detected an error with the web proxy service. |
