The following example is the script file version of the command:
create snapshotVirtualDisk sourceVirtualDisk=
"Mars_Spirit_4" repositoryRAIDLevel=5
repositoryPhysicalDiskCount=5 physicalDiskType=
SAS userLabel="Mars_Spirit_4_snap1"
repositoryUserLabel="Mars_Spirit_4_rep1"
warningThresholdPercent=75
repositoryPercentOfSource=40
repositoryFullPolicy=failSnapShot;
NOTE: In the previous examples, the names for the snapshot virtual disk and repository virtual disk
are defined by the user. If you do not choose to create names for the snapshot virtual disks or the
repository virtual disks, the RAID controller modules provide default names. (See Names Of
Snapshot Virtual Disks And Repository Virtual Disks for an explanation of naming conventions.)
Names Of Snapshot Virtual Disks And Repository Virtual Disks
The names of snapshot virtual disks and repository virtual disks can be any combination of alphanumeric
characters, hyphens, and underscores. The maximum length of the virtual disk names is 30 characters.
You must enclose the name in quotation marks. The character string cannot contain a new line.
Make sure that you use unique names or the RAID controller module firmware returns an error.
One technique for naming the snapshot virtual disk and the repository virtual disk is to add a hyphenated
suffix to the original name of the source virtual disk. The suffix distinguishes between the snapshot virtual
disk and the repository virtual disk. For example, if you have a source virtual disk with a name Engineering
Data, the snapshot virtual disk can have a name Engineering Data-S1. The repository virtual disk can have
a name of Engineering Data‑R1.
If you do not choose a unique name for either the snapshot virtual disk or repository virtual disk, the RAID
controller modules create a default name by using the name of the source virtual disk. For example, if the
name of the source virtual disk is aaa and it does not have a snapshot virtual disk, then the default name
is aaa‑1. If the source virtual disk already has n – 1 number of snapshot virtual disks, then the default
name is aaa‑n. Similarly, if the name of the source virtual disk is aaa and it does not have a repository
virtual disk, then the default repository virtual disk name is aaa‑R1. If the source virtual disk already has
n – 1 number of repository virtual disks, then the default name is aaa-R n.
In the examples from the previous section, the user‑defined name of the snapshot virtual disk was
Mars_Spirit_4_snap1. The user‑defined name of the repository virtual disk was Mars_Spirit_4_rep1. The
default name provided by the RAID controller module for the snapshot virtual disk would be
Mars_Spirit_4-1. The default name provided by the RAID controller module for the repository virtual disk
would be Mars_Spirit_4-R1.
Changing Snapshot Virtual Disk Settings
The set (snapshot) virtualDisk command enables you to change the property settings for a
snapshot virtual disk. Using this command, you can change the following parameters:
• Name of the snapshot virtual disk
• Warning threshold percent
• Repository full policy
