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.
