Dissociating snapshots

Last published : Jun 19, 2026
The Management Server console lets you dissociate a snapshot and turn it into an independent volume.
In the Veritas InfoScale Operations Manager console, you can perform this operation from the following contexts:
  • Data volume
  • Snapshot volume
When a data volume is selected, an error page is displayed if the selected data volume's disk group is in a deported or foreign state.
When a snapshot volume is selected, an error page is displayed if the selected snapshot volume's disk group is in a deported or foreign state.
The operation is not supported on Windows host.
To perform this task, your user group must be assigned the Admin role on the host or the Server perspective. The permission on the host may be explicitly assigned or inherited from a parent Organization.

  1. In the Management Server console, go to the Server perspective and expand Manage in the left pane.
  2. Expand the Organization or Uncategorized Hosts to locate and select the host.
  3. Expand the host and select Volumes.
  4. Right-click on the required volume and select Snapshot>Dissociate.
  5. The Dissociate Snapshot wizard panel displays information about all the snapshots available for the selected data volume. You can select the snapshots to be dissociated. Click Next.
  6. In the Dissociate Snapshot Summary wizard panel, verify the details of the data volume and snapshots selected to be dissociated. Click Finish.
  7. In the Result panel, verify that the selected snapshots have been dissociated successfully.
