I have a historically flaky MSA1500 with 2xMSA20 enclosures attached. Recently a disk failed in one of the enclosures.
The LCD display reports that interim state recovery for all volumes was successful.
On hot-swapping the failed drive, one of the volumes failed to rebuild with error:
112 VOLUME #0 REBUILD FAILURE
The other 5 volumes have successfully rebuilt.
According to the manual here:
"When the volume is still operating in regenerative mode, remove the new SCSI drive that was added as a replacement for the original failed drive and replace it with a different new drive."
How can I ascertain that the system is in regenerative mode before replacing the replacement disk? Is the fact that the interim state recovery is still effectively in operation?
