The COPYSET command copies one or more members of a volume set to another volume set. The master must be copied first, because it contains information that must be placed on the member volumes. The source volumes must be mounted in the LONER state, and the destination volumes must be mounted in the SCRATCH or UNKNOWN state.
Allows the copying of an entire volume set. Additionally, it enforces the integrity of the target and source volume sets to prevent intermixing of original and copied volumes.
Task |
 |
Copies the contents of one volume set to another volume set.
Capability |
|
CV, create mountable volume set
Syntax |
|
volutil: COPYSET [SNAME=]sname [FROM=]from_ldev
[TO]=to_ldev [GEN]=gen_number
|
Parameters |
|
- sname
The volume set that will be copied. The master volume of the set must be copied first. Required.
- from_ldev
A number from 1 to 100 specifying the logical device number of the destination volume that must be configured into the device class DISC and have a volume mounted in the LONER state. Use the DSTAT command to determine the state of the volume. Required.
- to_ldev
Must identify a volume mounted in the SCRATCH or UNKNOWN state. Required.
- gen_number
A number from 1 to 32767 specifying the new generation number of the copied volume set. Optional. If it is omitted, the generation number will be one greater than the original volume set.
Example |
|
This example shows how to copy one member of a volume set to another.
Place the master of the volume set you want to copy in the LONER state by using the VSCLOSE system command. If the master volume is not online when you mount the member volumes, the member volumes will mount in the LONER state.
Use the DSTAT command to verify that the source volumes are mounted in the LONER, and the destination volumes are mounted in the SCRATCH or UNKNOWN state.
Copy the master to the other volume set.

LDEV-TYPE STATUS VOLUME (VOLUME SET - GEN)
--------- ------ -------------------------
21-079330 LONER BVOL1 (BSET-0)
22-079330 LONER BVOL2 (BSET-0)
23-079350 LONER BVOL6 (BSET-0)
41-079350 SCRATCH
42-079350 SCRATCH
43-079350 SCRATCH
volutil: COPYSET SNAME=BSET FROM=21 TO=41

After the volume has been copied, both volumes (the source and the target) would be LONER volumes.
