Script Commands 133
Create Snapshot Virtual Disk
This command creates a snapshot virtual disk. When you use this command,
you can define the snapshot virtual disk in one of three ways:
• User-defined physical disks
• User-defined disk group
• User-defined number of physical disks for the snapshot virtual disk
If you choose to define a number of physical disks, the RAID controller
module firmware chooses which physical disks to use for the snapshot virtual
disk.
NOTE: Refer to "Preparing Host Servers to Create an Initial Snapshot Virtual Disk"
on page 65.
NOTICE: 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 will help to guarantee a stable copy of the
drive for the Snapshot.
