Re: Remove a drive

Rob,  There is a way to mark the drive you want to remove as "read-only".
I think this was a ptf in v5r1 maybe built into v5r2(not sure).  The PTF
had the moniker of "Drain-PTF".

What happens is this.  you mark the drives you want to remove as read only.
Then move the data off of them
Then when at DST you can remove the drives from the config.  Since there is
minimal data on them the remove goes quickly.

Ask your CE for specifics.

========================================

We are in the process of removing several 4gb and 8gb drives.  Actually a
complete tower full.  We are getting rid of these two spd towers and
putting in one new one.  To reduce downtime we want to get started before
downtime.  Thus we stuck six 35gb drives into the main tower.  Even with
raid striping taken in to effect, with the 6 new 35gb drives thrown in, it
should even out the old drives, until the new tower gets installed with
it's new drives.

V5R2.

We ran STRASPBAL TYPE(*ENDALC) on the old drives.  Then we ran STRASPBAL
TYPE(*MOVDTA).  Checking the status with CHKASPBAL until the move was
done.  The old drives dropped from 83% to 16%.  Then we ran STRASPBAL
TYPE(*CAPACITY) to balance the load better.

I see that STRSST has facilities to add a drive, but not to remove a
drive.  To do the last bit, will that have to wait until we can get into
DST?
