Removing Disks From a Pool
8. Define a new virtual disk process, $V2. Associate this VDP with $P1. Specify the
catalog locations based on the information obtained in Step 3:
50-> ADD DISK $V2, TYPE VIRTUAL, SENDTO STORAGE, POOL $P1, ANTLOCATION
$D2.ZYS00000.A0000000, pendopslocation $D2.ZYS00000.A0000001
9. Verify that all the objects associated with pool $P2 are now associated with $P1:
51-> INFO $P1, DETAIL
The system responds:
STORAGE - Detailed Info POOL \INCLINE.$P1

Removing Disks From a Pool
Before you can remove a physical disk from a pool, you must make sure there are no
logical files on it. This action can be accomplished by either purging or relocating those
files. To ensure that no more logical files are created on the disk you are excluding, you
should isolate it.
Example
Suppose that the SMF subsystem ($ZSMS, the pool processes and VDPs) is up and
running. Suppose you have a pool process, $POOL, that uses virtual disk process
$VDP. The pool process contains a disk, $DISK, that you need to remove from that
pool.
For D-series releases, use these commands:
1. Isolate the disk:
PUP ISOLATE $DISK, POOL $POOL
