SnapshotDiskDevice ( %host_storvol_unc_name%, DEMAND_ALLOCATED, SAME, %new_storvol_name%,
WAIT )
Host Storage Volume UNC Name
(%host_storvol_unc_name%). Select or enter the UNC name of the
host disk device to be copied.
Snapshot Type
. Select
demand_allocated
or
fully_allocated
.
RAID Level
. Select the redundancy level for the copy. Choices are
