Snapshot Virtual Disks

15 Click Finish to create the snapshot virtual disk and the associated

snapshot repository virtual disk.

16 After you have created one or more snapshot virtual disks, mount or

reassign a drive letter of the source virtual disk.

17 If needed, assign host-to-virtual disk mapping between the snapshot

virtual disk and the host operating system that accesses it.

NOTE:

In some cases, depending on the host type and any virtual disk

manager software in use, the software prevents you from mapping the same

host to both a source virtual disk and its associated snapshot virtual disk.

18 If you are using a Linux-based system, run the hot_add utility to register

the snapshot virtual disk with the host operating system.

NOTE:

The hot_add utility is not needed for Windows.

Specifying Snapshot Virtual Disk Names

Choose a name that helps you associate the snapshot virtual disk and

snapshot repository virtual disk with its corresponding source virtual disk. The

following information is useful when naming virtual disks:

• By default, the snapshot name is shown in the Snapshot virtual disk name

field as:
<source-virtual disk-name>—<sequence-number>
where sequence-number is the chronological number of the snapshot

relative to the source virtual disk.
The default name for the associated snapshot repository virtual disk that is

shown in the

Snapshot repository virtual disk field is:

<source-virtual disk-name>—R<sequence-number>
For example, if you are creating the first snapshot virtual disk for a source

virtual disk called

Accounting, the default snapshot virtual disk is

Accounting-1, and the associated snapshot repository virtual disk default

name is

Accounting-R1. The default name of the next snapshot virtual

disk you create based on Accounting is

Accounting-2, with the

corresponding snapshot repository virtual disk named as

Accounting-R2 by

default.
