Cloning Storage Volumes

Cloning with ISM provides an additional layer of protection because it allows you to make identical copies of the data on your volumes as you need them.

The original volume is the source volume, and the volume that receives the cloned data is the destination volume. The destination volume must be a different volume from the source volume. Cloned data belongs to a clone pool. Use the ISMData Clone pool and the ISMLogs Clone pool for your cloned volumes.

The requirements for cloning storage volumes with ISM follow:

To clone a file-type storage volume before it is full
  1. If the volume is already mounted, you must unmount it to change the Backup status. This action ensures that no new data is written to the file-type volume during the cloning operation.

    If the volume is already unmounted, change the Backup status for the volume to Disabled.

  2. To clone a volume, use the following command: 
    ism_clone -volume name
    1. Specify the name of the volume to clone.
    2. Specify the name of the clone pool (Default Clone, ISMData Clone, or ISMLog Clone).
  3. Mount the selected storage volume and cloned volume.
