We had an incident with a shelf from from our MD3660i when replacing a disk drive.  During the replacement seemingly several drives on the shelf went into a missing state.  I did not see more than two disks from any of our four Disk groups (RAID 6).  We powered down the enclosure, reseated the connectors for the problematic shelf and brought the system back up.

One of the disk groups is showing as Failed, but the member disks are optimal.  The recovery guru in the GUI refers us to Technical Support, but it seems unlikely that we will get any for a seven year old system.  I noticed the command "revive DiskGroup" in the cli documentation and was wondering if this is the only/next step in trying to recover the disk group and its associated virtual disk. 

Thanks,
