procCrash
(enterprises.17163.1.52.4.0.1)

Healthy

A procCrash trap signifies that a process managed by PM has crashed and left a core file. The variable sent with the notification indicates which process crashed.

A process has crashed and subsequently been restarted by the system. The trap contains the name of the process that crashed. A system snapshot associated with this crash has been created on the appliance and is accessible via the CLI or the Management Console. Riverbed Support might need this information to determine the cause of the crash. No other action is required on the appliance as the crashed process is automatically restarted.

admissionMapiError
(enterprises.17163.1.52.4.0.60)

Degraded

New MAPI connections will be passed through due to high connection count.

The total number of MAPI optimized connections have 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 appliance. The appliance reserves the remaining 15 percent so the MAPI admission control does not affect the other protocols. The 85 percent threshold is applied only to MAPI connections.

RiOS is now passing through MAPI connections from new clients but continues to intercept and optimize MAPI connections from existing clients (including new MAPI connections from these clients).

RiOS continues optimizing non-MAPI connections from all clients. This alarm is disabled by default.

The alarm clears automatically when the MAPI traffic has decreased; however, it can take one minute for the alarm to clear.

RiOS preemptively closes MAPI sessions to reduce the connection count in an attempt to bring the appliance out of admission control by bringing the connection count below the 85 percent threshold. RiOS closes the MAPI sessions in this order:

(enterprises.17163.1.52.4.0.66)

Needs Attention

One or more licensed features will expire within the next two weeks.

Choose Administration > Maintenance: Licenses and look at the Status column to see which licenses are about to expire. One or more feature licenses are scheduled to expire within two weeks.

This alarm is triggered per feature. Suppose you installed two license keys for a feature, LK1-FOO-xxx, which is going to expire in two weeks, and LK1-FOO-yyy, which is not expired. Because one license for the feature is valid, the alarm does not trigger.

licenseExpired
(enterprises.17163.1.52.4.0.67)

Degraded

One or more licensed features have expired.

Choose Administration > Maintenance: Licenses and look at the Status column to see which licenses have expired. One or more feature licenses have expired.

This alarm is triggered per feature. Suppose you installed two license keys for a feature, LK1-FOO-xxx (expired), and LK1-FOO-yyy (not expired). Because one license for the feature is valid, the alarm does not trigger.

clusterDisconnectedSHAlertError
(enterprises.17163.1.52.4.0.68)

Degraded

A cluster SteelHead has been reported as disconnected.

Choose Networking > Network Integration: Connection Forwarding and verify the configuration for both this appliance and the neighbor SteelHead. Verify that the neighbor is reachable from this appliance.

Verify that a delegate user has been added to the appliance and is configured with the appropriate privileges.

linkDuplex
(enterprises.17163.1.52.4.0.70)

Degraded

An interface on the appliance is in half-duplex mode.

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.

Choose Networking > Networking: Base Interfaces and examine the appliance 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 do not support automatic duplex, configure both ends for full duplex.

linkIoErrors
(enterprises.17163.1.52.4.0.71)

Degraded

An interface on the appliance is suffering I/O errors.

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 should experience few errors. The alarm clears when the error rate drops below 0.05 percent.

To troubleshoot, try a new cable and a different switch port. Another possible cause is electromagnetic noise nearby.

You can change the default alarm thresholds by entering the alarm link_io_errors err-threshold <threshold-value> command at the system prompt. For details, see the Riverbed Command-Line Interface Reference Manual.

storageProfSwitchFailed

Either Critical or Needs Attention, depending on the state

Storage profile switch failed.

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 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 and selecting a storage profile.

A storage profile switch requires a reboot of the Edge. The alarm appears after the reboot.

These reasons can cause a profile switch to fail:

When you encounter this error, reboot the Edge and then switch the storage profile again. If the switch succeeds, the error clears. If it fails, RiOS reverts the Edge to the previous storage profile.

clusterIpv6IncompatiblePeerError
(enterprises.17163.1.52.4.0.74)

Degraded

(enterprises.17163.1.52.4.0.75)

Critical

Flash disk hasn't been backed up due to not enough free space on /var filesystem.

Indicates that the USB flash drive has not been backed up because there is not 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.

datastoreNeedClean
(enterprises.17163.1.52.4.0.76)

Critical

The data store needs to be cleaned.

You need to 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.

pathSelectionPathDown
(enterprises.17163.1.52.4.0.77)

Degraded

Path Selection - A path went down.

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 appliance directs traffic through another available path. When the original path comes back up, the appliance redirects the traffic back to it.

clusterNeighborIncompatibleError
(enterprises.17163.1.52.4.0.80)

Degraded

At least one node in the cluster is incompatible.

graniteUncommittedDataError
(enterprises.17163.1.52.4.0.10006)

Degraded

The level of uncommitted data is too high.

The difference between the contents of the blockstore and the Core-side LUN is significant. This alarm checks for how much uncommitted data is in the Edge cache as a percentage of the total cache size.

This alarm triggers when the appliance writes a large amount of data very quickly, but the WAN pipe is not large enough to get the data back to the Core fast enough to keep the uncommitted data percentage below 5 percent. As long as data is being committed, the cache will flush eventually.

The threshold is 5 percent, which for a 4 TB (1260-4) system is 200G. To change the threshold, use this command:

For example:

 

For details on the CLI command, see the SteelFusion Command-Line Interface Reference Manual.

To check that data is being committed, go to Storage > Reports: Blockstore Metrics on the Edge.
