RE: Removing drives from system -- MIDRANGE-L

Yeah. It just bugs me to drop even a nother nickel on this box. No users to worry about - just a couple of twinax line printers.

Actually the Spend Money key would be easier and faster.
#1 Get Replacement Drive
#2 STRSST and signin if needed
Start a Service Tool, Hardware Service Manager, Device Concurrent
Maintenance
#3 Give the tool DDxxx resource name and tell it to remove
Watch the blinking light and pull the drive
#4 Repeat step #3 with the Insert Option and insert the replacement drive
#5 Backout to main SST menu, then Work with disk units, Work with disk unit
recovery
and finaally Rebuild disk unit data

This can all be done with users on the system...

BTW Thanks Larry, I didn't know we could do this without replacing the
drive.

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.
