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" on page 72 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 the 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
