Converting a snapshot Virtual Disk to read-write

Use the Convert Snapshot Virtual Disk to Read-Write option a to convert a read-only snapshot virtual disk to a read-write snapshot virtual disk.

You can use the Convert Snapshot Virtual Disk to Read-Write option for these storage objects:
  • Snapshot virtual disk
  • Consistency group member’s snapshot virtual disk
The conversion operation requires that a repository be provisioned to support write operations on the snapshot virtual disk.
  1. From the AMW, select the Storage & Copy Services tab.
  2. Select either a snapshot virtual disk or a consistency group member’s snapshot virtual disk and then select Copy Services > Snapshot Virtual disk > Convert to Read-Write.
  3. Select how you want to create the repository for the Read-Write snapshot virtual disk. Do one of the following:
    • Select Automatic to create the snapshot virtual disk repository with the default capacity settings. This is the recommended option.
    • Select Manual to define the properties for the snapshot virtual disk repository. Use this option if you want to specify all of the customizable settings for the snapshot virtual disk repository. The Manual method is considered advanced and only those who understand physical disk consistency and optimal physical disk configurations should use this method.
  4. Click Convert to convert the read-only snapshot virtual disk to read-write.
    The snapshot virtual disk or consistency group member’s snapshot virtual disk table as read- write is displayed under the Mode column, and the Repository columns are now populated.
