Dell MD3200, MD3220 owner manual Snapshot Repository Capacity, 152

•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 characters, the default names for the snapshot and its associated snapshot repository virtual disk use the source virtual disk name truncated enough 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 GR-R1.

Snapshot Repository Capacity

If you receive a warning that the capacity for the snapshot repository virtual disk is approaching its threshold, you can increase the capacity of a snapshot repository virtual disk by using one of the following methods:

•Use the free capacity available on the disk group of the snapshot repository virtual disk.

•Add unconfigured capacity to the disk group of the snapshot repository virtual disk. Use this option when no free capacity exists on the disk group.

You cannot increase the storage capacity of a snapshot repository virtual disk if the snapshot repository virtual disk has any one of the following conditions:

•The virtual disk has one or more hot spare drives in use.

•The virtual disk has a status other than Optimal.

•Any virtual disk in the disk group is in any state of modification.

•The controller that has ownership of this virtual disk is currently adding capacity to another virtual disk. Each controller can add capacity to only one virtual disk at a time.

•No free capacity exists in the disk group.

•No unconfigured capacity is available to add to the disk group.
