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-numberis 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.

•Whether you use the software-supplied sequence number that (by default) populates the Snapshot virtual disk name or the Snapshot repository virtual disk name field, the next default name for a snapshot or snapshot repository virtual disk still uses the sequence number determined by the software. For example, if you give the first snapshot of source virtual disk Accounting the name Accounting-8, and do not use the software- supplied sequence number of 1, the default name for the next snapshot of Accounting is still Accounting-2.

•The next available sequence number is based on the number of existing snapshots of a source virtual disk. If you delete a snapshot virtual disk, its sequence number becomes available again.

•You must choose a unique name for the snapshot virtual disk and the snapshot repository virtual disks, or an error message is displayed.

•Names are limited to 30 characters. After you reach this limit in either the snapshot virtual disk name or the Snapshot repository virtual disk name fields, you can no longer type in the field. If the source virtual disk is 30
