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: 1 In the AMW, select the Logical tab, select a snapshot virtual disk. 2 Select Virtual Disk Snapshot Re-create. 3 Type yes, and click OK. Disabling a Snapshot Virtual Disk Disable a snapshot virtual disk if one of the following conditions exists: • You do not need the snapshot now. • You intend to re-create the snapshot at a later time and want to retain the associated snapshot repository virtual disk so that you do not need to create it again. • You want to maximize storage array performance by stopping copy-onwrite activity to the snapshot repository virtual disk.
