Names Of Snapshot Virtual Disks And Repository Virtual Disks

The names of snapshot virtual disks and repository virtual disks can be any combination of alphanumeric characters, hyphens, and underscores. The maximum length of the virtual disk names is 30 characters. You must enclose the name in quotation marks. The character string cannot contain a new line. Make sure that you use unique names or the RAID controller module firmware returns an error.

One technique for naming the snapshot virtual disk and the repository virtual disk is to add a hyphenated suffix to the original name of the source virtual disk. The suffix distinguishes between the snapshot virtual disk and the repository virtual disk. For example, if you have a source virtual disk with a name Engineering Data, the snapshot virtual disk can have a name Engineering Data-S1. The repository virtual disk can have a name of Engineering Data‑R1.

If you do not choose a unique name for either the snapshot virtual disk or repository virtual disk, the RAID controller modules create a default name by using the name of the source virtual disk. For example, if the name of the source virtual disk is aaa and it does not have a snapshot virtual disk, then the default name is aaa‑1. If the source virtual disk already has n – 1 number of snapshot virtual disks, then the default name is aaa‑n. Similarly, if the name of the source virtual disk is aaa and it does not have a repository virtual disk, then the default repository virtual disk name is aaa‑R1. If the source virtual disk already has n – 1 number of repository virtual disks, then the default name is aaa-R n.

In the examples from the previous section, the user‑defined name of the snapshot virtual disk was Mars_Spirit_4_snap1. The user‑defined name of the repository virtual disk was Mars_Spirit_4_rep1. The default name provided by the RAID controller module for the snapshot virtual disk would be Mars_Spirit_4-1. The default name provided by the RAID controller module for the repository virtual disk would be Mars_Spirit_4-R1.
