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.
