Failed disk in a RAID set – Why does it remain active?

Can anyone provide me with more information on a failed disk in the RAID array. I checked out the WRKDSKSTS today to get information on the failed disk. To my surprize, it was very active, although still in a failed state. Can anyone explain how a failed drive can continue to operate? I thought it would not work after failure. Is it a recoverable unit that can be added back as a normal drive? What tests can I do to check pout the drives? Where can I get the instructions. I am at V5R3.

Thanks. We'll let you know when a new response is added.

I have progressed a little further with this problem.

I thought that if a drive failed, there would be no activity on the drive. You would see this in the WRKDSKSTS command where the stats on the failed drive should all be zero. They were not.

I have restarted my machine into manual mode and went to DST and work with disk units. Options, 4, then 2, then option 12.

The system identified the failed drive and I was able to rebuild the drive. The system recovered everything on the unit. Its up and running without problems… so far.

I guess the lesson learned is they do not always fail completely. I will get a replacement unit to keep on hand.
