Subject: Catastrophic disk failure

Hi,

We experienced a disk drive failure and were unconcerned since we had replacements available and believed that RAID5 was protecting us.
Now our technician is not sure whether our disks are actually protected.

Can someone tell me what the DST screen should show if our drives actually have RAID enabled? We can't get through an IPL but we can boot it into DST at least.
We are afraid we may have to rebuild from a system save tape.
