When half the disks dropped of the array at the same time, it gave up and corrupted the RAID 5 meta data so that even after removing the offending drive, the array didn't recover. The restore from backup tape near 48hrs as it was near the end of our monthly backup cycle and 28 'incremental' tapes had to be loaded. It was a mail spool as well, so the incrementals were reasonably large. We changed the backup schedule after that to do full dumps more often so less tapes would be required to restore it :-)
