Normal RAID behavior when a drive fails:
The drive shows failed This drive is replaced The drive automatically rebuilds OR The drive show up as configured and a rebuild can manually be started

Nov 2011

• ipp064 drive 3 failed Show FAILED and was replaced. Still showed FAILED. This was not normal. I (Cindy)took the drive offline and put it back online. This is what I have to do for some of my 3ware arrays ( not the ipp 3ware arrays ). This is what can be done to rebuild a drive that is already part of the array - but not a new drive. It caused corruption in the data.
• ipp058 drive 20 failed, showed FAILED and was replaced. Still showed FAILED. Under direction from LSI - who admitted this was not normal - I was able to start rebuild on the new drive. It rebuilt. We get a message every 24 hours. Controller ID: 0 Reminder: Potential non-optimal configuration due, PD commissioned as Emergency spare: --:--:20 LSI stated that marking the drive as an Emergency Spare is normal for this driver, it is a good thing - this warning should not be generated. This is the warning he is asking the engineers about.
• LSI sends new driver, Gavin installs it on 1pp064 and ipp058.
• ipp056 drive fails. Gavin installs the driver and reboots the machine. We replace the drive and it automatically rebuilds. It also generated the warning.
