Table 27. Event descriptions and recommended actions (continued)
Number Severity Description/Recommended actions
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 preceding 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 the preceding steps, contact
technical support.
595 Info. This event reports the serial number of each controller module in this system.
Recommended actions:
No action is required.
596 Warning Enclosure fault protection has been compromised for the indicated disk group.
To replace the failed disk, the system was unable to find a spare that met requirements to
minimize the risk of data loss in the event of enclosure failure, so the system had to select a
spare that did not meet the requirements. For a RAID-6 disk group, this means that more than
two member disks are in the same enclosure. For other RAID levels, this means that more than
one member disk is in the same enclosure.
Recommended actions:
Replace the indicated failed disk in the indicated enclosure to restore enclosure fault
protection.
597 Warning Drawer fault protection has been compromised for the indicated disk group.
To replace the failed disk, the system was unable to find a spare that met requirements to
minimize the risk of data loss in the event of drawer failure, so the system had to select a spare
that did not meet the requirements. For a RAID-6 disk group, this means that more than two
member disks are in the same drawer. For other RAID levels, this means that more than one
member disk is in the same drawer.
Recommended actions:
Replace the indicated failed disk in the indicated enclosure to restore drawer fault protection.
598 Warning, Info. Drive has failed a performance measurement.
Recommended actions:
Monitor the disk.
599 Error The firmware has yet to retrieve Enclosure Power control status.
The Enclosure Power element provides enclosure level power control. This could occur shortly
after a reboot or module insertion. It should only be treated as an error if it persists for more
than 30 seconds after a reset.
Recommended actions:
Contact technical support.
When the problem is resolved, an event with the same code will be logged with Resolved
severity.
Warning,
Resolved
The firmware has yet to retrieve Enclosure Power control status.
The Enclosure Power element provides enclosure level power control.
