        Right after I sent the mail, I RTFM'ed and found the answer that was
suggested about "voldg -f". That's what happens when you're trying to fix
things at 9 pm.

        I only got to test it on Friday and it worked fine. I got my disk
group back and replaced the disk. The description in Debbie Trenta's
mail is exactly what I did to fix the problem.

        Thanks for all your help.

> voldisk rm <diskaccessname>

> 3) Label the new drive with the LSMpriv and LSMpubl areas.
> disklabel -e <disk>
> 4) Add the new disk
> voldisk -f init <diskaccessname>
> example: voldisk -f init rz17
> 5) Reconnect it to it's associated diskmedia name
> voldg -k adddisk <diskmedia>=<diskaccess>
> example: voldg -k adddisk ordsk01=rz17
> 6) Now start the recovery:
> volrecover -g <diskgroup> -sb
> example: volrecover -g oracledg -sb
> 7) Now in ASE you should be able to bring the service back
