Using the Snapshot Feature 69
See step 1 through step 4 in the preceding section, "Preparing Host Servers to
Create an Initial Snapshot Virtual Disk" on page 67. The following example
shows a command in which users assign the physical disks:
client>smcli 123.45.67.89 -c "create
snapshotVirtualDisk sourceVirtualDisk=
\"Mars_Spirit_4\" repositoryRAIDLevel=5
repositoryPhysicalDisks=(1,1 1,2 1,3 1,4 1,5);"
The command in this example creates a new snapshot of the source virtual
disk Mars_Spirit_4. The snapshot repository virtual disk consists of five
physical disks that form a new disk group. The new disk group has a RAID
level of 5. This command also takes a snapshot of the source virtual disk,
starting the copy-on-write operation.
See step 1 through step 4 in the preceding section, "Preparing Host Servers to
Create an Initial Snapshot Virtual Disk" on page 67. The following example is
the script file version of the command:
create snapshotVirtualDisk sourceVirtualDisk=
"Mars_Spirit_4" repositoryRAIDLevel=5
repositoryPhysicalDisks=(1,1 1,2 1,3 1,4 1,5);
A minimal version of this command might look like the following example:
client>smcli 123.45.67.89 -c "create
snapshotVirtualDisk sourceVirtualDisk=
\"Mars_Spirit_4\";"
The command in this example creates a new snapshot for the source virtual
disk Mars_Spirit_4. The repository virtual disk is created in the same disk
group as the source virtual disk, which means that the repository virtual disk
has the same RAID level as the source virtual disk. This command starts the
copy-on-write operation.
Refer to steps 1 through 4 in the preceding section, "Preparing Host Servers to
Create an Initial Snapshot Virtual Disk" on page 67. The following example is
the script file version of the command:
create snapshotVirtualDisk sourceVirtualDisk=
"Mars_Spirit_4";
