Volume Management
COPYVOL
The COPYVOL command copies the contents of one volume to a second volume.
This is a bit-wise copy of the source volume. The source must be mounted
in the SCRATCH, UNKNOWN, or LONER state. The destination volume must be
mounted in the SCRATCH or UNKNOWN state. Both volumes must have the same
physical characteristics. Use the DSTAT command to determine the state
of any volume.
Task
Copies the contents of one volume to another volume.
Capability
CV, create mountable volume set
Syntax
COPYVOL [FROM=] from_ldev [TO=] to_ldev
Parameters
from_ldev A number from 1 to 100 specifying the logical
device number of the source volume. Required.
to_ldev A number from 1 to 100 specifying the logical
device number of the destination volume. Required.
Example
This example shows how to copy data from one volume to another volume.
1. Use the VSCLOSE command to place the source volume in the LONER
state [REV BEG](this is only necessary if the volume is
mounted)[REV END]. The destination volume must be mounted in the
SCRATCH or UNKNOWN state. Both volumes must have the same
physical characteristics.
2. Use the COPYVOL command to copy the volume.

3. Use the DSTAT command to verify that the volume was copied.
CAUTION Mixing copied volumes with original volumes could have
disastrous effects. For example, if you make a backup of a
volume set, then continue to use the original volume set, file
and accounting information on the original may no longer
correspond to the copy. Any attempt to integrate a duplicate
volume into the original volume set would be disastrous.
