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.
