How is a snapshot virtual disk named?
Snapshot and Snapshot Repository Virtual Disk Default Names
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 related 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 make the first snapshot virtual disk for a source virtual disk called Accounting, the default snapshot
virtual disk is Accounting-1. The associated snapshot repository virtual disk default name is Accounting-R1. The default name of the next snapshot virtual disk you make based on Accounting is Accounting-2. The related snapshot repository virtual disk name is Accounting-R2 by default.
The subsequent information is useful when you give a virtual disk a name.
- You can use the software-supplied sequence number that populates the Snapshot virtual disk name or you can use the Snapshot repository virtual disk name field. However, the next default name for a snapshot or snapshot repository virtual disk will still use the sequence number
controlled by the software. For example, you name the first snapshot of source virtual disk Accounting AccountingMight18. You do not use the software-supplied sequence number of 1, but the default name for the next snapshot of Accounting is still
Accounting-2.
- The next available sequence number is based on the number of current snapshots of a source virtual disk. If you delete a snapshot
virtual disk, its sequence number becomes available again.
- You must set a unique name for the snapshot virtual disk and the snapshot repository virtual disks, or an error message is
shown.
- There is a 30-character limit. 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 characters, the default names for the snapshot
and its associated snapshot repository virtual disk truncate the source virtual disk name to add the sequence string. For
example, for Host Software Engineering Group GR-1, the default snapshot name is Host Software Engineering GR-1, and the default repository name would be Host Software Engineering G-R1.
