Pete,
From a V7R3 system, I see this.
When running Raid5, I think it's normal to see Unprotected for the ASP
Display Disk Configuration Protection
Serial Resource Hot Spare
ASP Unit Number Type Model Name Protection Protection
1 Unprotected
1 Y6804KV02VAX 5B21 109 DMP001 RAID 5 Y
2 Y6804KV02WUX 5B21 109 DMP007 RAID 5 Y

So, this thread has made me nervous. What *should* I see? When I look at parity protection on my IBM i (7.4) I see this:
Display Disk Configuration Protection
Serial Resource Hot Spare
ASP Unit Number Type Model Name Protection Protection
1 Unprotected
1 Y210WAE1FB13 5B41 099 DMP001 RAID 5 N
2 Y210WAE0RMT0 5B41 099 DMP005 RAID 5 N
3 Y210WAE0NBG9 5B41 099 DMP007 RAID 5 N
4 Y210WAE1CV48 5B41 099 DMP003 RAID 5 N
5 Y210WAE15BLD 5B41 099 DMP009 RAID 5 N
6 Y210WAE0S2YD 5B41 099 DMP013 RAID 5 N
7 Y210WAE15BNN 5B41 099 DMP011 RAID 5 N
Display Device Parity Status
Parity Resource Hot Spare
Set ASP Unit Type Model Name Status Protection
1 57D8 001 DC01 RAID 5 N
1 2 5B41 099 DMP005 Active
1 4 5B41 099 DMP003 Active
1 3 5B41 099 DMP007 Active
1 1 5B41 099 DMP001 Active
1 7 5B41 099 DMP011 Active
1 6 5B41 099 DMP013 Active
1 5 5B41 099 DMP009 Active
Is it the protection status in the "Display Disk Configuration Protection" that clues me in that I am "Unprotected"? So the RAID 5 status tells me what, exactly?

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.
