After your server has been prepared, see "Creating the Initial Snapshot Virtual Disk" on page 66. Creating the Initial Snapshot Virtual Disk After first preparing the host server(s) as specified in the preceding procedure, use the following examples to make a virtual disk snapshot. The following syntax is the general form of the command to create a snapshot virtual disk: create snapshotVirtualDisk sourceVirtualDisk= "sourceVirtualDiskName" [repositoryRAIDLevel=(0 | 1 | 5) (repositoryPhysicalDisks= (enclosureID0,slotID0 ... enclosureIDn,slotIDn) userLabel="snapshotVirtualDiskName" warningThresholdPercent=percentValue repositoryPercentOfSource=percentValue repositoryUserLabel="repositoryName" repositoryFullPolicy=(failSourceWrites | failSnapShot)] [enclosureLossProtect=(TRUE | FALSE)] NOTE: Use one or all of the optional parameters as needed to help define your configuration. You do not, however, need to use any optional parameters. 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 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. 66 Using the Snapshot Feature

Using the Snapshot Feature
After your server has been prepared, see "Creating the Initial Snapshot Virtual
Disk" on page 66.
Creating the Initial Snapshot Virtual Disk
After first preparing the host server(s) as specified in the preceding procedure,
use the following examples to make a virtual disk snapshot.
The following syntax is the general form of the command to create a snapshot
virtual disk:
create snapshotVirtualDisk sourceVirtualDisk=
"
sourceVirtualDiskName"
[repositoryRAIDLevel=(0 |
1 | 5) (repositoryPhysicalDisks=
(
enclosureID0,slotID0 ... enclosureIDn,slotIDn
)
userLabel="
snapshotVirtualDiskName
"
warningThresholdPercent=
percentValue
repositoryPercentOfSource=
percentValue
repositoryUserLabel="
repositoryName"
repositoryFullPolicy=(failSourceWrites |
failSnapShot)] [enclosureLossProtect=(TRUE | FALSE)]
NOTE:
Use one or all of the optional parameters as needed to help define your
configuration. You do not, however, need to use any optional parameters.
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
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.
