Hi, on a DMX800, can disk firmware be upgarded on a RAID set by RAID set basis, or does the whole DMX800 need to take an outage? (Not talking about controller firmware).
Thanks.
 
As far as I know, you can upgrade the scsi code on a selected-disk base or all disk drives.

Cheers.

You have several options when doing a SCSI code upgrade:
1. Upgrade by director. (single director upgrade)
2. Upgrade a single disk.
3. Upgrade by drive type. (all drives of the same type)
4. Upgrade all drives. (all drives in a mixed drive configuration)
This can be done online or offline. Suggest doing during low activity. You do not have the option of doing by Raid set.
