Table 27. Event descriptions and recommended actions (continued)
Number Severity Description/Recommended actions
● No action is required.
462 Error The indicated virtual pool reached its storage limit.
There are three thresholds, two of which are user-settable. The third and highest setting is
set automatically by the controller and cannot be changed. This event is logged with Warning
severity if the high threshold is exceeded and the virtual pool is overcommitted. Overcommitted
means that the total committed size of all virtual volumes exceeds the physical space in the
virtual pool. If the storage usage drops below a threshold, event 463 is logged.
Recommended actions:
● You should immediately take steps to reduce storage usage or add capacity.
Warning The indicated virtual pool exceeded its high threshold for allocated pages, and the virtual pool is
overcommitted.
There are three thresholds, two of which are user-settable. The third and highest setting is
set automatically by the controller and cannot be changed. This event is logged with Warning
severity if the high threshold is exceeded and the virtual pool is overcommitted. Overcommitted
means that the total committed size of all virtual volumes exceeds the physical space in the
virtual pool. If the storage usage drops below a threshold, event 463 is logged.
Recommended actions:
● You should immediately take steps to reduce storage usage or add capacity.
Info. The indicated virtual pool exceeded one of its thresholds for allocated pages.
There are three thresholds, two of which are user-settable. The third and highest setting is
set automatically by the controller and cannot be changed. This event is logged with Warning
severity if the high threshold is exceeded and the virtual pool is overcommitted. Overcommitted
means that the total committed size of all virtual volumes exceeds the physical space in the
virtual pool. If the storage usage drops below a threshold, event 463 is logged.
Recommended actions:
● No action is required for the low and mid thresholds. However, you may want to determine
if your storage usage is growing at a rate that will result in the high threshold being crossed
in the near future. If this will occur, either take steps to reduce storage usage or purchase
additional capacity.
● If the high threshold is crossed, you should promptly take steps to reduce storage usage or
add capacity.
463 Info. The indicated virtual pool has dropped below one of its thresholds for allocated pages.
This event indicates that a condition reported by event 462 is no longer applicable.
Recommended actions:
● No action is required.
464 Warning A user inserted an unsupported cable or SFP into the indicated controller host port.
Recommended actions:
● Replace the cable or SFP with a supported type.
465 Info. A user removed an unsupported cable or SFP from the indicated controller host port.
Recommended actions:
● No action is required.
466 Info. The indicated virtual pool was deleted.
Recommended actions:
● No action is required.
467 Info. Addition of the indicated disk group completed successfully.
