As it should!! Glad to hear your date is back in the land of the
protected!
There is one HUGE no-no when it comes to failed Load Source in a RAID
environment: DO NOT stop the operating system until the drive is
replaced. Unless is has been fixed with newer RAID cards, (Which I
simply don't have the guts to try...) the system cannot IPL from a dead
load source drive even though it's RAID protected. Thus it is extremely
important to replace and rebuild that drive with all available alacrity!
If you have MIRRORed data protection the mirrored pair can be used to IPL
(Note that if you use remote load source mirroring you will need to
physically swap the good member of the pair with the bad one - um, so know
where that guy lives!!)

RE: load source concurrent maintenance
Update:
Concurrent maitenance on load source works. I was able to replace and
rebuild the disk through SST/DST.

Hey Lukas,
I have 3 partitions running V5R3 on an 825 and disk protection is your
regular RAID5.
My primary partition has the failed load source in the system unit.

for the possibility of replacing the disk through concurrent maintenance.
That's certainly possible, but it depends on a lot of factors.
a) What OS Level are you running?
b) What kind of disk protection is used for the load source?
c) What kind of machine are you running?
d) What kind of disk cage is the load source is (HP/NHP)?
Every halfway new machine (POWER5 and newer) always have Hot Plug
disks - for the model 270 and similar, they were optional, and i'm not
sure about the 8xx models...
