Table 27. Event descriptions and recommended actions (continued)
Number Severity Description/Recommended actions
● If a spare is available, replace the SSD now.
Info. The indicated SSD has 20% or less of its life remaining.
This event will be logged again with a severity of Warning as the SSD further approaches its end
of life.
Recommended actions:
● Obtain a replacement SSD of the same type and capacity if you do not already have one
available.
503 Info. The Intelligent BackEnd Error Monitor (IBEEM) has discovered that continuous errors are being
reported for the indicated PHY.
IBEEM logged this event after monitoring the PHY for 30 minutes.
Recommended actions:
● No action is required.
504 Info. Service debug access to the system has been enabled or disabled by a user. Allowing service
debug access may have security implications. After the diagnosis is complete you may want to
disallow such access.
Recommended actions:
● No action is required.
505 Warning The indicated virtual pool was created with a size smaller than 500 GB, which can lead to
unpredictable behavior.
The storage system may not perform correctly.
Recommended actions:
● Add disk groups to the virtual pool to increase the size of the pool.
506 Info. Addition of the indicated disk group was started.
When this operation is complete, event 467 is logged.
Recommended actions:
● No action is required.
507 Info. The link speed of the indicated disk does not match the link speed that the enclosure is capable
of.
This event is logged when the auto-negotiated link speed is less than the maximum speed that
the enclosure supports. The disk is functional, but I/O performance is reduced. This event may
be logged for one disk channel or for both disk channels.
Recommended actions:
● If the disk is a member of a non-fault-tolerant disk group (RAID 0 or non-RAID), move the
data to a different disk group.
● 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.
508 Error The indicated virtual pool went offline. All of its volumes also went offline.
All data in the virtual pool has been lost. This condition can be caused by corrupt or inaccessible
virtual pool metadata.
Recommended actions:
● Check for other events that indicate faults in the system and follow the recommended
actions for those events.
● Re-create the virtual pool.
● Restore the data from a backup, if available.
