Description/Recommended actions
Resolved
A SES alert for a current sensor in the indicated enclosure has been resolved.
Recommended actions:
•
No action is required.
562
Info.
Virtual pool statistics have been reset.
Recommended actions:
•
No action is required.
563
Info.
A disk has been restarted.
Recommended actions:
•
No action is required.
565
Warning
One of the PCIe buses is running at less than optimal speed.
This event is the result of a hardware problem that has caused the controller to run slower than expected. The
system works, but I/O performance is degraded.
Recommended actions:
•
Replace the controller module that logged this event.
566
Info.
One of the DDR ports has been busy for at least 5 minutes.
This event is the result of a speed compensation while handling short data blocks. The system is operational
but I/O performance is degraded.
Recommended actions:
•
No action is required.
568
Info.
A disk group has mixed physical sector size disks (for example 512n and 512e disks in the same disk group).
This event is the result of the user selecting disks with sector formats that do not match or a global spare
replacement with a different sector format than the disk group. This could result in degraded performance for
some workloads.
Recommended actions:
•
No action is required.
571
Error
Allocated snapshot space exceeded the configured percentage limit of the virtual pool.
If the snapshot space limit policy is set to delete snapshots, the system will begin to delete snapshots
according to the snapshot retention priority setting until the snapshot space usage drops below the configured
limit. Otherwise, the system will begin to use general pool space for snapshots until snapshots are manually
deleted. If the storage usage drops below a threshold, event 572 is logged.
Recommended actions:
•
If the snapshot space limit policy is set to notify only, you should immediately take steps to reduce
snapshot space usage or add storage capacity.
•
If the snapshot space policy is set to delete, the system will reduce snapshot space automatically, or log
event 573 if no snapshots can be deleted.
Warning
Allocated snapshot space exceeded the high snapshot space threshold.
The high threshold setting indicates that the pool is nearly out of snapshot space. The threshold settings are
intended to indicate that the pool is using a significant portion of configured snapshot space and should be
monitored. If the storage usage drops below any threshold, event 572 is logged.
