Using the Snapshot Feature

71

The following example of the

create snapshotVirtualDisk

command includes

user-defined parameters:

client>smcli 123.45.67.89 -c "create

snapshotVirtualDisk sourceVirtualDisk=

\"Mars_Spirit_4\" repositoryRAIDLevel=5

repositoryPhysicalDiskCount=5 physicalDiskType=

SAS userLabel=\"Mars_Spirit_4_snap1\"

repositoryUserLabel

Specifies the name to give to the snapshot repository
virtual disk. If you do not choose a name for the
snapshot repository virtual disk, the RAID controller
modules create a default name using the source virtual
disk name. For example, if the source virtual disk name
is

Mars_Spirit_4

and it does not have an associated

snapshot repository virtual disk, the default snapshot
repository virtual disk name is

Mars_Spirit_4-R1

. If the

source virtual disk already has

n

– 1 number of snapshot

repository virtual disks, the default name is

Mars_Spirit_4-R

n

.

warningThresholdPercent

Specifies how full to allow the snapshot repository
virtual disk to get before sending a warning that the
snapshot repository virtual disk is close to capacity. The
warning value is a percentage of the total capacity of the
snapshot repository virtual disk. The default value is 50,
which represents 50 percent of total capacity. (Change
this value using the

set snapshotVirtualDisk

command.)

repositoryPercentOfSource Specifies the size of the snapshot repository virtual disk

as a percentage of the source virtual disk size. The
default value is 20, which represents 20 percent of the
source virtual disk size.

repositoryFullPolicy

Specifies how snapshot processing continues if the
snapshot repository virtual disk is full. You can choose to
fail writes to the source virtual disk (

failSourceWrites

)

or fail writes to the snapshot virtual disk
(

failSnapShot

). The default value is

failSnapShot

.
