Re-creating Snapshot Virtual Disks

You can re-create a snapshot virtual disk that you have previously disabled.

CAUTION: Possible loss of data redundancy – If the snapshot virtual disk is in Optimal status, it is first disabled prior to being re-created. This action invalidates the current snapshot.

Keep these important guidelines in mind when you re-create a snapshot virtual disk:

•To re-create the snapshot virtual disks correctly, follow the instructions for your operating system.

NOTE: Failing to follow these additional instructions could create unusable snapshot virtual disks. For more information, see the PowerVault Modular Disk Storage Manager online help topics.

•To use this option, the snapshot virtual disk must be either in an Optimal status or Disabled status.

•When using this option, the previously configured snapshot name parameters and snapshot repository virtual disk are used.

To recreate the snapshot virtual disk:

1In the AMW, select the Logical tab, select a snapshot virtual disk.

2Select Virtual Disk→ Snapshot→ Re-create.

3Type yes, and click OK.

Snapshot Rollback

The snapshot rollback feature allows you to revert the contents of a virtual disk to match a point-in-time image existing on a snapshot virtual disk.

During a rollback, the host server can still write data to the base virtual disk. However, the snapshot virtual disk is set as read-only during the rollback operation and becomes available for write operations immediately after the rollback is complete. The snapshot virtual disk cannot be restarted, deleted, or disabled during the rollback operation.
