<type> | • iscsi - This alarm indicates that the iSCSI module has encountered an error. • 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. Note: The license expiring and license expired alarms are triggered per feature. For example, if you install two license keys for a feature, LK1-FOOxxx (expired) and LK1-FOO-yyy (not expired), the alarms do not trigger, because the feature has one valid license. |
• link_duplex - This alarm is triggered when an interface was not configured for half-duplex negotiation but has negotiated half-duplex mode. Half-duplex significantly limits the optimization service results. This alarm is enabled by default. • link_io_errors - This alarm is triggered when the link error rate exceeds 0.1% 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 should experience very few errors. The alarm clears when the rate drops below 0.05%. This alarm is enabled by default. • 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.

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. • model_unlicensed - This alarm indicates that the model license has been removed or is expired. • 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 pre-existing 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: alarm non_443_ssl_servers_detected_on_upgrade clear | |

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.
