CreateSnapshot command
Syntax
CreateSnapshot ~
-Pit NameofPiT [LastInstance | LastAsyncMirror |LastSyncMirror] , ~
-snapshot SnapshotName [TEMPLATE], ~
-host HostName1 RW|OFF, [-host HostName2 RW|OFF,] ~
-StoragePool PoolName, ~
-cluster 0|1, -timeout 900
Description
Creates a snapshot.
NOTE:
• The -host argument is considered optional by the VSM API, but is required by the VSM (returns
an error).
• If [Template] is used, the name of the object must be less than 16 characters long.
If the LastInstance flag is used, the preceding PiT name is the root name, and the most recently
created snapshot PiT (with a template name) is used.
If the LastAsyncMirror/LastSyncMirror flag is used, the preceding PiT name is the root name,
and the most recently created async/sync mirror PiT on the specific virtual disk is used.
NOTE:
This root name is different from the asynchronous/synchronous mirror template name. You must
retrieve this root name from the list of PiTs defined on the specific virtual disk.
