•  fan_error - This alarm indicates that the system has detected a fan error.

•  flash_error - This alarm indicates that the system has detected 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 cannot 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, enter the reload command to automatically power cycle the SteelHead and restore the flash drive to its proper function. On desktop SteelHead appliance x50 and x55 models, you must physically power cycle the appliance (push the power button or pull the power cord).

•  flash_protection_failed - This alarm indicates that the USB flash drive has not been backed up because there is not enough available space in the /var filesystem directory.

•  hardware - This alarm indicates the overall health of the hardware.

•  inbound_qos_wan_bw_err - Enables an alarm and sends an email notification if 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.

•  ipmi - This alarm indicates that the system has detected an Intelligent Platform Management (IPMI) event. This alarm is not supported on all appliance models.

•  licensing - This alarm is the parent licensing alarm and triggers if any of the license_expired, license_expiring, or appliance_unlicensed alarms are active.

•  license_expired - This alarm triggers if any feature has at least one license installed, but all of them are expired.

•  license_expiring - This alarm triggers if one or more features is going to expire within two weeks.

•  linkstate: <x> - These alarms indicate that the system has detected a link that is down. The system notifies you through SNMP traps, email, and alarm status. By default, this alarm is not enabled. The no alarm linkstate enable command disables the link state alarm.

•  memory_error - This alarm indicates that the system has detected a memory error.

•  mismatch_peer_aggr - This alarm 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 clears automatically.

•  nfs_v2_v4 - This alarm indicates that the system has triggered a v2 or v4 NFS alarm.

•  non_443_ssl_servers_detected_on_upgrade - This alarm indicates that during a RiOS upgrade (for example, from 5.5 to 6.0), 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 either add a peering rule to the server-side SteelHead to intercept the connection and optimize the SSL traffic on the non-default SSL server port or you can add an in-path rule to the client-side SteelHead to intercept the connection and optimize the SSL traffic on the non-default SSL server port. After adding a peering or in-path rule, you must clear this alarm manually by issuing the following CLI command:

•  optimization_general - This alarm indicates that the optimization service is not operating normally. The service might not be running, it might be disabled, or it might have stopped optimizing.

•  optimization_service - This alarm indicates that the system has encountered an optimization service condition.

•  other_hardware_error - This alarm indicates that the system has detected a problem with the SteelHead hardware. The alarm clears when you add the necessary hardware, remove the nonqualified hardware, or resolve other hardware issues. The following issues trigger the hardware error alarm:

•  outbound_qos_wan_bw_err - Enables an alarm and sends an email notification if 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.

•  paging - This alarm indicates whether 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, then reboot the system. If rebooting does not solve the problem, contact Riverbed Support.

•  path_selection_path_down - This alarm indicates that one of the predefined uplinks for a connection is unavailable because it has exceeded either the timeout value for uplink latency or the threshold for observed packet loss.

•  path_selection_path_probe_err - This alarm indicates that a path selection monitoring probe for a predefined uplink has received a probe response from an unexpected relay or interface.

•  power_supply - This alarm indicates that an inserted power supply cord does not have power, as opposed to a power supply slot with no power supply cord inserted.

•  profile_switch_failed - This alarm indicates that an error has occurred while repartitioning the disk drives during a storage profile switch. A profile switch changes the disk space allocation on the drives, clears the SteelFusion and VSP data stores, and repartitions the data stores to the appropriate sizes. You switch a storage profile by using the disk-config layout command on an EX or EX+ SteelFusion SteelHead. By default, this alarm is enabled.

•  raid_disk_indiv - This alarm indicates that the system has encountered RAID errors (for example, missing drives, pulled drives, drive failures, and drive rebuilds). 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.

•  secure_transport_controller_unreachable - This alarm indicates a network connectivity failure to the Controller for the secure transport feature. Issues that might trigger this alarm are Controller services down because of an upgrade or a network connectivity failure to the Controller.

•  secure_transport_registration_failed - This alarm indicates that the peer SteelHead is not registered with the Controller and the Controller does not recognize it as a member of the secure transport group.

•  secure_vault - This alarm indicates a general secure vault error.

•  secure_vault_rekey_needed - This alarm indicates whether the system has detected that the secure vault needs to be rekeyed.

•  secure_vault_uninitialized - This alarm indicates that the system has detected that the secure vault is uninitialized.

•  secure_vault_unlocked - This alarm indicates whether the secure vault is unlocked. When the vault is unlocked, SSL traffic is not optimized and you cannot encrypt a data store.

•  service_error - This alarm cannot be disabled. It indicates that the system has detected a software error in the SteelHead service. The SteelHead service continues to function, but an error message that you should investigate appears in the logs.

•  single_cf - This alarm indicates that the connection to a SteelHead connection forwarding neighbor is lost.
