Hello ng,

I have do do a firmware update on the storage boxes. This means I will
have to take one part of our VXVM RAID1 Mirror down, do the upgrade
and then bring it back up again.

The problem here with is, that all the volumes will have to do a full
resync.

Is there any posibility to avoid that?

eg. with SVM I can:
- metaoffline d50 d52
- Upgrade one box
- metaonline d50 d52

and in this way avoid the sync of 700GB worth of volumes.

I was considering something like:

- vxmend off
- Upgrade one box
- vxmend on
- vxplex att

Please give me some advice what would be the best way to do this with
vxvm.

Greetings
