Re: Replacing Failing SSA Disk

IF hdisk0 to hdisk16 are occupied (defined),
you will get an hdisk17 automatically when cgfmgr runs.
I don't think you can rename a logical disk to anything you
want.

Subject: Replacing Failing SSA Disk

I am getting an SSA_DISK_ERR4 error on my J40 running
AIX 4.3.3. The disk is in a mirrored VG. I have
never replaced a disk on a running system before, so
I'd feel better if someone would look over the
procedure I'm planning to follow and let me know if I
am overlooking anything. Thanks very much.

unmirrorvg oravg hdisk17
reducevg oravg hdisk17
rmdev -l hdisk17 -d
[replace disk drive, let the drive be renamed hdisk17]
extendvg oravg hdisk17
mirrorvg oravg
