Number Severity Description/Recommended actions
54 Info. Battery needs replacing.
The battery provides backup power for the real-time (date/time) clock. In the event of a power
failure, the date and time will revert to 1980-01-01 00:00:00.
Recommended actions:
● Replace the controller module that logged this event.
55 Warning The indicated disk reported a SMART event.
A SMART event indicates impending disk failure.
Recommended actions:
● Resolve any non-disk hardware problems, especially a cooling problem or a faulty power
supply.
● If the disk is in a disk group that uses a non-fault-tolerant RAID level (RAID 0 or non-RAID),
copy the data to a different disk group and replace the faulty disk.
● If the disk is in a disk group that uses a fault-tolerant RAID level, check the current state of
the disk group. If it is not FTOL then back up the data as data may be at risk. If it is FTOL
then replace the indicated disk. If more than one disk in the same disk group has logged a
SMART event, back up the data and replace each disk one at a time. In virtual storage it may
be possible to remove the affected disk group, which will drain its data to another disk group,
and then re-add the disk group.
56 Info. A controller has powered up or restarted.
Recommended actions:
● No action is required.
58 Error A disk drive detected a serious error, such as a parity error or disk hardware failure.
Recommended actions:
● Replace the failed disk with one of the same type (SSD, enterprise SAS, or midline SAS) and
the same or greater capacity. For continued optimum I/O performance, the replacement disk
should have performance that is the same as or better than the one it is replacing.
Warning A disk drive reset itself due to an internal logic error.
Recommended actions:
● The first time this event is logged with Warning severity, if the indicated disk is not running
the latest firmware, update the disk firmware.
● If this event is logged with Warning severity for the same disk more than five times in one
week, and the indicated disk is running the latest firmware, replace the disk with one of the
same type (SSD, enterprise SAS, or midline SAS) and the same or greater capacity. For
continued optimum I/O performance, the replacement disk should have performance that is
the same as or better than the one it is replacing.
Info. A disk drive reported an event.
Recommended actions:
● No action is required.
59 Warning The controller detected a parity event while communicating with the indicated SCSI device. The
event was detected by the controller, not the disk.
Recommended actions:
● If the event indicates that a disk or an expansion module is bad, replace the indicated device.
Info. The controller detected a non-parity error while communicating with the indicated SCSI device.
The error was detected by the controller, not the disk.
