206 Script Commands
Notes
If a value is entered for the repository storage space that is too small for the
replication repository virtual disks, the RAID controller module firmware
returns an error message that indicates the amount of space needed for the
replication repository virtual disks. The command does not try to change the
replication repository virtual disk. The command can be re-entered using the
value from the error message for the repository storage space value.
When you assign the physical disks, if you set the
enclosureLossProtect parameter to TRUE and have selected more
than one physical disk from any one enclosure, the storage array returns an
error. If you set the enclosureLossProtect parameter to FALSE, the
storage array performs operations, but the disk group that you create might
not have enclosure loss protection.
When the RAID controller module firmware assigns the physical disks, if you
set the enclosureLossProtect parameter to TRUE, the storage array
returns an error if the RAID controller module firmware cannot provide
physical disks that result in the new replication repository virtual disk having
enclosure loss protection. If you set the enclosureLossProtect
parameter to FALSE, the storage array performs the operation even if it
means that the replication repository virtual disk might not have enclosure
loss protection.
Re-create Snapshot
This command starts a new copy-on-write operation by using an existing
snapshot virtual disk. You can re-create a single snapshot virtual disk or re-
create multiple virtual disks.
CAUTION: Before you create a new point-in-time image of a source virtual disk,
stop any data access (I/O) activity or suspend data transfer to the source virtual
disk to ensure that you capture an accurate point-in-time image of the source
virtual disk. Close all applications, including Windows Internet Explorer, to make
sure all I/O activity has stopped.
NOTE: Removing the drive letter of the associated virtual disk in Windows or
unmounting the virtual drive in Linux helps guarantee a stable copy of the drive for
the Snapshot.

Creating a Snapshot Virtual Disk

Explains three methods for defining physical disks for snapshot repository virtual disks.

Creating a Snapshot Virtual Disk with User-Assigned Physical Disks

Explains creating a snapshot virtual disk by choosing available physical disks, which automatically creates a new disk group.

Creating the Initial Snapshot Virtual Disk

Provides syntax and examples for creating a virtual disk snapshot after preparing the host server.

Creating a Snapshot Virtual Disk with Software-Assigned Physical Disks

Explains creating a snapshot virtual disk by letting software assign physical disks to an existing disk group.

Creating a Snapshot Virtual Disk by Specifying a Number of Physical Disks

Details creating a snapshot virtual disk by specifying the number of physical disks and RAID level for a new disk group.
