Spinning up and down isn't the issue.
According to the warning displayed when you do a disk_fw_update, even upgrading a single disk,
"It involves... suspending all disk I/O to all disks while that is happening"
SUSPENDING ALL DISK I/O TO **ALL** (not ONE) DISKS.
That's a problem in my environment.
So I guess the question is, is the notice wrong and when you're only doing a disk_fw_update on a single disk that's allocated as a spare, it doesn't suspend I/O to ALL disks?
ONTAP 6 will be very cool. I'm looking forward to being able to install it soon. I particularly appreciate the new logging features so I can see who did what when.
Thanks, MD

As i said you can upgrade a single disk with "disk_fw_update <disk>" without service disruption while this disk is a spare. Again, you have to specify the disk. Also does a disk firmware upgrade not take 2 minutes per disk if you use disk_fw_update.

BTW: ONTAP 6.0 and higher is supposed to do a automatic update when you insert a disk with older firmware (have not tried it yet). Cool, isn't it?
