This is for the Dell R610 Perc H700 Raid controller for our archiver appliance. We would like to keep our disk configurations the same at all times, so the system disk will always be in slot 0 [00:00:00] , while the backup disk in slot 1 [00:00:01] and the data disks in slot 2 [00:00:02] and 3 [00:00:03]. Deleting a VD in the PERC H700 RAID Menu will not destroy the data on the disk, but initializating DOES destroy the data. Replace failed system disk The instructions below will basically remove the bad system disk, put the backup system disk into slot 0 and add the new disk into slot 1, thus keeping our disk configurations in place.

Replace failed data disk If there is a failure with one data disk, identify the disk simply via OpenManagement web interface (https://nodename:1311). Replace the disk with a new one WHILE the system is running or kept on. This is very important. Never turn off the system to replace a failed data disk like we do for the system disk replacement. As soon as the new disk is inserted, the controller will automatically rebuild the disk for mirroring. The progress of rebuild can be monitored via "omreport storage pdisk controller=0" or via https://nodename:1311. The system should be functional while rebuilding in progress. In case a data disk failure is caused by a power outage, always turn on the system when the power is restored, and then replace the disk. In short, alway replace a data disk while the system is on or running.
