When you stop the copy-on-write operations for a specific FlashCopy logical drive, only that FlashCopy
logical drive is disabled. All of the other FlashCopy logical drives stay in operation.
When you want to restart a copy-on-write operation, use the
re-create flashcopy logicalDrive
command or the
re-create flashcopy collection
command. The
re-create flashcopy logicalDrive
command starts a fresh copy-on-write operation by using an existing FlashCopy logical drive.
Note: The FlashCopy logical drive must be in either an Optimal state or a Disabled state.
When you restart a FlashCopy logical drive, these actions occur:
v
All copy-on-write data previously on the FlashCopy repository logical drive is overwritten.
v
FlashCopy logical drive parameters and FlashCopy repository logical drive parameters stay the same
as the previously disabled FlashCopy logical drive and the previously disabled FlashCopy repository
logical drive. You can also change the
userLabel
parameter, the
warningThresholdPercent
parameter,
and the
repositoryFullPolicy
parameter when you restart the FlashCopy logical drive.
v
The original names for the FlashCopy repository logical drive are retained.
This example shows how to restart a FlashCopy logical drive:
c:\...\...\client>smcli 123.45.67.89 -c “re-create flashcopy logicalDrives [\”Mars_Spirit_4-2\”
\”Mars_Spirit_4-3\”];”
This example shows how to use the command in a script file:
re-create flashcopy logicalDrives [“Mars_Spirit_4-2” “Mars_Spirit_4-3”];
If you do not intend to use a FlashCopy logical drive again, you can delete the FlashCopy logical drive
by using the
delete logicalDrive
command. When you delete a FlashCopy logical drive, the associated
FlashCopy repository logical drive also is deleted.
