RE: Turn off mirroring, turn on raid

Turning Mirroring ON I know is done DURING an IPL, turning it off is most 
likely done via DST. If I remember correctly... turning OFF mirroring leaves 
the you with half of your drives un-configured.

NEW RAID5 sets are built using DST. You can add drive concurrently to a raid 
set but not build new sets.

So I think the steps would be...

IPL to DST
Turn off Mirroring
IPL thru STORAGE-MANAGEMENT
Build the raid sets
ADD new disks to ASP
Finish the IPL

Hope this helps

Subject: Turn off mirroring, turn on raid


Customer has 14 drives, protected using mirroring.

If he turns off mirroring, and then turns on Raid, (assuming he has correct 
controller), how does this work?

Really my question is not how to turn on Raid, but is the system usable while 
the drives are "Raiding"?  Do they just show
unprotected while the raid set is being built?  Or is this part of IPL and we 
have to wait.

Thanks.
