Stopping and Deleting a Snapshot Virtual Disk

Page 74 highlights

The following example is the script file version of the command: set virtualDisk ["Mars_Spirit_4-1"] userLabel= "Mars_Odyssey_3-2"; 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"]; 74 Using the Snapshot Feature

Using the Snapshot Feature
The following example is the script file version of the command:
set virtualDisk ["Mars_Spirit_4-1"] userLabel=
"Mars_Odyssey_3-2";
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_4-
3\"];"
The following example is the script file version of the command:
stop snapshot virtualDisks ["Mars_Spirit_4-2"
"Mars_Spirit_4-3"];
