Using the Snapshot Feature
67
Refer to steps 1 through 4 in the preceding section, "Preparing Host Servers to
Create an Initial Snapshot Virtual Disk" on page 65. 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 65. The following example is
the script file version of the command:
create snapshotVirtualDisk sourceVirtualDisk=
"Mars_Spirit_4";
Creating a Snapshot Virtual Disk with Software-Assigned Physical
Disks
This version of the create snapshotVirtualDisk command lets you choose an
existing disk group in which to place the snapshot repository virtual disk. The
storage management software determines which physical disks to use. You can
also define how much space to assign to the repository virtual disk. Because
you are using an existing disk group, the RAID level for the snapshot virtual
disk defaults to the RAID level of the disk group in which you place it. You
cannot define the RAID level for the snapshot virtual disk. The general syntax
for this command is:
create snapshotVirtualDisk sourceVirtualDisk=
" sourceVirtualDiskName" [repositoryDiskGroup=
diskGroupNumber freeCapacityArea=
freeCapacityIndexNumber userLabel=
