When you change the warning threshold percent and repository full policy, you can apply the changes to one or several snapshot virtual disks. The following example uses the set (snapshot) virtualDisk command to change these properties on more than one snapshot virtual disk: client>smcli 123.45.67.89 -c "set virtualDisks [\"Mars_Spirit_4-1\" \"Mars_Spirit_4-2\" \"Mars_Spirit_4-3\"] warningThresholdPercent=50 repositoryFullPolicy=failSourceWrites;" The following example is the script file version of the command: set virtualDisks ["Mars_Spirit_4-1" "Mars_Spirit_4-2" "Mars_Spirit_4-3"] warningThresholdPercent=50 repositoryFullPolicy= failSourceWrites; Stopping and Deleting a Snapshot Virtual Disk When you create a snapshot virtual disk, copy-on-write immediately starts running. As long as a snapshot virtual disk is enabled, storage array performance is affected by the copy-on-write operations to the associated snapshot repository virtual disk. If you no longer want copy-on-write operations to run, you can use the stop snapshot virtualDisk command to stop the copy-on-write operations. When you stop a snapshot virtual disk, the snapshot virtual disk and the repository virtual disk are still defined for the source virtual disk; only copy-on-write has stopped. The following example stops a snapshot virtual disk: client>smcli 123.45.67.89 -c "stop snapshot virtualDisks [\"Mars_Spirit_4-2\" \"Mars_Spirit_43\"];" The following example is the script file version of the command: stop snapshot virtualDisks ["Mars_Spirit_4-2" "Mars_Spirit_4-3"]; When you stop the copy-on-write operations for a specific snapshot virtual disk, only that snapshot virtual disk is disabled. All other snapshot virtual disks remain in operation. 74 Using the Snapshot Feature
