Number Severity Description/Recommended actions
•
Recommended actions:
•
•
173 Info. The indicated disk group has been removed from quarantine.
Recommended actions:
•
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:
•
175 Info. The network-port Ethernet link has changed status (up or down) for the indicated controller.
Recommended actions:
•
•
It contains data in a format that is not supported by this system. The controller does not support linear
disk groups.
If the disk group was quarantined because not all of its disks are accessible:
• If event 173 has subsequently been logged for the indicated disk group, no action is required. The disk
group has already been removed from quarantine.
• Otherwise, perform the following actions:
• Check that all enclosures are powered on.
• Check that all disks and I/O modules in every enclosure are fully seated in their slots and that their
latches are locked.
• Reseat any disks in the quarantined disk group that are reported as missing or failed in the user
interface. (Do NOT remove and reinsert disks that are not members of the disk group that is
quarantined.)
• Check that the SAS expansion cables are connected between each enclosure in the storage
system and that they are fully seated. (Do NOT remove and reinsert the cables because this can
cause problems with additional disk groups.)
• Check that no disks have been removed from the system unintentionally.
• 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.
No action is required.
No action is required.
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.
