Netware 6.0 SP5, 1.5 GHz 1024 Mb ram, 2 adaptec 29160N SCSI cards, Sony tape trive on one, two hard drives on the other.

Earlier this week I came in to work to what looked like a hard drive failure during the night during my backup. After pondering and attempting a few things, I started to restore the contents of the volume to another drive on another server. While this was working I did some more exploring and tried list devices to find out if the server was seeing all the drives. After a few seconds wait, the drive activated as did the pool and then the volume mounted. All was well, or so it seemed.

Today, over lunch the same thing happened, only I was performing a backup tape merge into my existing database rather than backing up. This time the list devices did not reactivate things for me. After some reasearch I found out how to rebuild the pool, took about an hour. Now the drive, pool and volume are back up and again seem to be working.

My question is, am I looking at a hard drive that is failing or could there have been some corruption in the volume that caused the device to de-activate?

Any help greatly appreciated.
