SCF Reference Manual for the Storage Subsystem (G06.28+, H06.05+, J06.03+)

Deleting a Storage Pool
Use the “DELETE POOL Command” (page 251) to delete a storage pool.
Considerations for DELETE POOL
• Before deleting a storage pool process from the system configuration database, you must
delete the virtual disks associated with the pool and reconfigure the physical volumes.
• The storage pool process you are deleting:
Must be stopped◦
◦ Cannot contain any physical volumes
◦ Cannot have any virtual disks associated with it
• The storage pool catalogs must be available
• TMF must be running.
• The SMF master process ($ZSMS) must be started.
• The CATALOGLOCATION volume for the MON process must be started, and it must be
enabled by TMF.
• The CATALOGLOCATION volume for the storage pool process must be started, and it must
be enabled by TMF.
• If, for any reason, the SMF master process does not give permission to delete the storage pool
process, you are prompted to continue deletion, even though this might cause discrepancies
in the SMF catalog.
Example
1. Identify the physical and virtual volumes associated with the pool:
-> INFO $POOL5, DETAIL
STORAGE - Detailed Info POOL \COMM.$POOL5

Physical Volumes:
$P5D04 $P5D03 $P5D02 $P5D01
Virtual Volumes:
$VDISK01 $VDISK02 $VDISK03 $VDISK04 $VDISK05 $VDISK06 $VDISK07 $VDISK08 $VDISK09
$VDISK11 $VDISK12 $VDISK13 $VDISK14 $VDISK15 $VDISK16 $VDISK17 $VDISK18 $VDISK19
2. Delete the virtual disks associated with $POOL5:
-> DELETE DISK $*, SUB VIRTUAL, POOL $POOL5
3. Remove the following physical volumes from the storage pool:
