5. Restart the disk process:
-> START $VDISK00
Deleting a Virtual Disk
The “DELETE DISK Command” (page 248) removes a virtual disk from the system configuration
database.
Considerations for DELETE DISK and Virtual Disks
• For the DELETE DISK command to succeed:
The process must be stopped or not running before you can delete it.◦
◦ TMF must be running.
◦ $ZSMS must be in the STARTED state.
◦ The storage pool process specified by the POOL attribute must be started.
◦ The CATALOGLOCATION volume for the MON process must be started and must be
enabled by TMF.
◦ The CATALOGLOCATION volume for the storage pool process must be started and
enabled by TMF.
◦ The ANTLOCATION and PENDOPSLOCATION volumes for the virtual disk must be
started, they must be enabled in TMF, and they must be configured to be in a storage
pool.
◦ If a virtual disk has a system configuration database record, you can delete it even if the
SMF master process ($ZSMS) has no knowledge of that record.
• If, for any reason, the virtual disk process cannot be started or the SMF Master process does
not give permission to delete the virtual disk, you are prompted to continue with the delete,
even though deletion might cause discrepancies in SMF catalogs.
• Example
1. Verify the disk is in the STOPPED state, substate DOWN:
-> STATUS $VDISK00
If the disk is not stopped, see “Stopping a Virtual Disk” (page 151).
2. Delete the disk from the system configuration database:
-> DELETE DISK $VDISK00
3. Verify the disk is deleted:
-> INFO $VDISK00
Managing a Virtual Disk
Virtual disk management tasks include:
• “Starting a Virtual Disk” (page 150)
• “Resetting a Virtual Disk” (page 151)
• “Stopping a Virtual Disk” (page 151)
• “Swapping Processors for a Virtual Disk” (page 152)
Starting a Virtual Disk
The “START DISK Command” (page 274) puts the virtual disk process into the STARTED state.
