RE: Removing drives from system -- MIDRANGE-L

Well, DST is certainly the easier option. That must have been what I did last time. I recall moving all the data off a raid set and then swapping out those drives.

Thanks.

Roger,

I don't believe you can do what you want to do with a failed raid set. I'm
pretty sure you will need to fix the failed drive/set then you could remove
the drive. I know that is not what you want to do. The only thing I can
think of doing if you can't buy a drive ( Those drives should be dirt cheap
these days ), is to stop raid on another set, remove a drive from the ASP
and use it to replace the failed drive.

While replacing the failed drive and rebuilding raid can be done
concurrently, stopping raid5 requires a dedicated system.

I have an (obviously) old 720 with a failed 6717-070 drive. It's one of
five in the cage and part of a raid set. I want to kill that raid set,
remove the drive and bring it up on just the remaining 4 drives. It is not
the load source. I've done this long ago to swap out drives. Can't recall
the steps though. I don't think I had to use DST but that's what I see on
the IBM site.

Any suggestions? I just need to limp along for about another month or so -
just to support a couple of twinax devices - no users.

Thanks.
