Recopying a
Volume Use the
recopy volumeCopy
command to create a new volume copy for a
previously defined copy pair that has a status of Stopped, Failed, or Completed. You
can use the
recopy volumeCopy
command to create backups of the target
volume. Then, you can copy the backup to tape for off-site storage. When you use the
recopy volumeCopy
command to make a backup, you cannot write to the source
volume while the recopy operation is running. The recopy operation might take a long
time.
When you run the
recopy volumeCopy
command, the data on the source volume
is copied in its entirety to the target volume.
ATTENTION Possible loss of data access
– The
recopy volumeCopy
command
overwrites existing data on the target volume and makes the target volume read-only
to hosts. The
recopy volumeCopy
command fails all of the snapshot (legacy)
volumes that are associated with the target volume, if any exist.
You can also reset the copy priority by using the
recopy volumeCopy
command
if you want to change the copy priority for the recopy operation. The higher priorities
allocate storage array resources to the volume copy at the expense of storage array
performance.
The command has this form:
recopy volumeCopy target [ targetName ] [source
[ sourceName ]

copyPriority=(highest | high | medium | low | lowest)

targetReadOnlyEnabled=(TRUE | FALSE)]
NOTE
You can use the optional parameters as needed to help define your
configuration.
This example shows the
show volumeCopy
command:
c:\...\sm X \client>smcli 123.45.67.88 123.45.67.89

-c “recopy volumeCopy target [\”Obi_1\”]
copyPriority=highest;”
The command in this example copies data from the source volume that is associated
with the target volume Obi_1 to the target volume again. The copy priority is set to
the highest value to complete the volume copy as quickly as possible. The underlying
consideration for using this command is that you have already created the volume
