Severity
Description/Recommended actions
￭
Check for other events that indicate faults in the system and follow the
recommended actions for those events. But, if the event indicates a failed disk and
the recommended action is to replace the disk, do NOT replace the disk at this time
because it may be needed later for data recovery.
￭
If the disk group is still quarantined after performing the steps, shut down both
controllers and then power down the entire storage system. Power it back up,
beginning with any disk enclosures (expansion enclosures), then the controller
enclosure.
￭
If the disk group is still quarantined after performing these recommended actions,
contact technical support.
●
If the disk group was quarantined because it contains data in a format that is not supported
by this system:
○
Recover full support and manageability of the quarantined disk groups and volumes by
replacing your controllers with controllers that support this type of disk group.
○
If you are sure that the data on this disk group is not needed, simply remove the disk
group, and thus the volumes, using the currently installed controllers.
173
Info.
The indicated disk group has been removed from quarantine.
Recommended actions:
●
No action is required.
174
Info.
Enclosure or disk firmware update has succeeded, been aborted by a user, or failed.
If the firmware update fails, the user will be notified about the problem immediately and should
take care of the problem at that time, so even when there is a failure, this event is logged as
Informational severity.
Recommended actions:
●
No action is required.
175
Info.
The network-port Ethernet link has changed status (up or down) for the indicated controller.
Recommended actions:
●
If this event is logged indicating the network port is up shortly after the Management
Controller (MC) has booted up (event 139), no action is required.
●
Otherwise, monitor occurrences of this event for an error trend. If this event occurs more
than 8 times per hour, it should be investigated.
○
This event is probably caused by equipment outside of the storage system, such as faulty
cabling or a faulty Ethernet switch.
○
If this event is being logged by only one controller in a dual-controller system, swap
the Ethernet cables between the two controllers. This will show whether the problem is
outside or inside the storage system.
○
If the problem is not outside of the storage system, replace the controller module that
logged this event.
176
Info.
The error statistics for the indicated disk have been reset.
Recommended actions:
●
No action is required.
177
Info.
Cache data was purged for the indicated missing volume.
Recommended actions:
●
No action is required.
181
Info.
One or more configuration parameters associated with the Management Controller (MC) have
been changed, such as configuration for SNMP, SMI-S, email notification, and system strings
(system name, system location, etc.).
Recommended actions:
●
No action is required.
