I'm a little rusty on SSA, but I never remember, unmounting, vary'ing
off or rebooting anything. I never even stopped the apps.

Are you upgrading the disk or the enclosure MC?

I did this *ONCE* without unmounting and varying off the volume
groups. Don't remember if I was updating the disks or the adaptor.
Had Terabytes of data magically disappear. I was able to recover
the volumes. (don't remember how)

Believe IBM's instructions when they say unmount and varyoff!!!!

Just to be sure my memory wasn't totally gone, I went through the
_disk_ MC upgrade screens for SSA disks:

MICROCODE
DOWNLOAD
802430


CAUTION:

Microcode may be downloaded to SSA disk drives while they are in use.
However, if you choose to perform the download while a disk drive
is busy the operating system or using applications may experience
temporary delays.

Downloading microcode to the selected disk drives may take up to
2 minutes.

Do you want to continue?

No
Yes


You shouldn't normally have problems. If you vary everything off then
you shouldn't either.
