v
If the base logical drive already has n -1 number of FlashCopy repository logical drives, the default
name is aaa-R n .
In the examples from the previous section, the user-defined FlashCopy logical drive name was
Mars_Spirit_4_EnhFlashCopy1, and the user-defined FlashCopy repository logical drive name was
Mars_Spirit_4_rep1. The default name that was provided by the controller for the FlashCopy logical drive
was Mars_Spirit_4-1. The default name that was provided by the controller for the FlashCopy repository
logical drive was Mars_Spirit_4-R1.
Changing FlashCopy Logical Drive Settings
Use the
set (FlashCopy) logicalDrive
command to change these property settings for a FlashCopy
logical drive:
v
The FlashCopy logical drive name
v
The warning threshold percent
v
The FlashCopy repository full policy
This example shows how to change a FlashCopy logical drive name.
c:\...\...\client>smcli 123.45.67.89 -c “set logicalDrive [\”Mars_Spirit_4-1\”]
userLabel=\”Mars_Odyssey_3-2\”;”
This example shows how to use the command in a script file:
set logicalDrive [“Mars_Spirit_4-1”] userLabel=”Mars_Odyssey_3-2”;
When you change the warning threshold percent and the FlashCopy repository full policy, you can apply
the changes to one or several FlashCopy logical drives with this command. This example shows how to
use the
set (FlashCopy) logicalDrive
command to change these properties on more than one FlashCopy
logical drive:
c:\...\...\client>smcli 123.45.67.89 -c “set logicalDrive
[\”Mars_Spirit_4-1\” \”Mars_Spirit_4-2\” \”Mars_Spirit_4-3\”
warningThresholdPercent=50
repositoryFullPolicy=failBaseWrites;”
This example shows how to use the command in a script file:
set logicalDrive [“Mars_Spirit_4-1” “Mars_Spirit_4-2”
“Mars_Spirit_4-3”] warningThresholdPercent=50
repositoryFullPolicy=failBaseWrites;
Stopping, Restarting, and Deleting a FlashCopy Logical Drive
When you create a FlashCopy logical drive, copy-on-write starts running immediately. As long as a
FlashCopy logical drive is enabled, storage subsystem performance is impacted by the copy-on-write
operations to the associated FlashCopy repository logical drive.
If you no longer want copy-on-write operations to run, you can use the stop flashcopy logicalDrive
command to stop the copy-on-write operations. When you stop a FlashCopy logical drive, the FlashCopy
logicalDrive and the FlashCopy repository logical drive are still defined for the base logical drive. Only
copy-on-write has stopped. This example shows how to stop a FlashCopy logical drive:
c:\...\...\client>smcli 123.45.67.89 -c “stop flashcopy logicalDrives [\”Mars_Spirit_4-2\”
\”Mars_Spirit_4-3\”];”
This example shows how to use the command in a script file:
stop flashcopy logicalDrives [“Mars_Spirit_4-2” “Mars_Spirit_4-3”];
