When Powering Off A Mirrored Disk And RAID Is Rebuilding, The Mirrored
Disk Is Not Powered Off [NSM 150] (7368)
Scenario
If you try to power off the mirrored disk when RAID is rebuilding, it is not
powered off. However, no message appears to inform you that your request for
power off has been denied.
The Disk Setup panel indicates that the drive is still active, confirming that
the disk has not been powered down.
Workaround
Wait for the RAID to rebuild and then power off the disk.
Changing The RAID Rebuild Rate Does Not Retain The New Setting [IBM
x3650] (5780)
Scenario
If you try to change the RAID Rebuild Rate, the slider returns to the default
setting of High. This setting of High affects other activities on the IBM x3650.
For example, if the system is rebooted, the storage server takes a long time to
start. The long start time means that the icon will continue blinking red in the
Console and, even after the system is up and the storage server started, the
unit’s performance is affected until the RAID rebuild completes.
Workaround
There is no workaround.
Explanation
This inability to change the RAID Rebuild Rate is due to a limitation in the
IBM controller firmware.
