NOTE:
Use one or all of the optional parameters as needed to define your
configuration. It is not necessary to use any optional parameters.
The following example is a command in which software assigns the physical
disks:
client>smcli 123.45.67.89 -c "create
snapshotVirtualDisk sourceVirtualDisk=
\"Mars_Spirit_4\" repositoryDiskGroup=2
freeCapacityArea=2;"
The command in this example creates a new snapshot repository virtual disk
in disk group 2. The source virtual disk is
Mars_Spirit_4
. The size of the
snapshot repository is 4 GB. This command also takes a snapshot of the
source virtual disk, which starts the copy-on-write operation.
Define the capacity of a snapshot repository virtual disk as any percentage of
the size of the source virtual disk. A value of 20 percent is a good compromise
between size and speed. In the previous example, the size of the snapshot
repository is set to 4 GB. The underlying assumption is that the source virtual
disk size is 20 GB (0.2 x 20 GB = 4 GB).
The following example is the script file version of the command:
create snapshotVirtualDisk sourceVirtualDisk=
"Mars_Spirit_4" repositoryDiskGroup=2
freeCapacityArea=2;
