Modifying an App VG

Last published : Jul 06, 2026
The Management Server Console lets you modify an application volume group (App VG). You can add or remove volumes from the App VG. You can also specify a new maximum IOPS value.
In clustered environments, the IOPS threshold for an App VG is propagated to all nodes in the cluster. The threshold applies independently to each node.
Note: If you clear the maximum IOPS value, the App VG is deleted. Similarly, if you remove all volumes from the App VG, the App VG is deleted. The volumes are not deleted.
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.
To modify an App VG
  1. In the Management Server console, go to the Server perspective and expandManage in the left pane.
  2. Expand Applications and expandDatabases to locate the database.
  3. In the App VGs tab, right-click the appropriate App VG and select Modify App VG.
  4. In the Modify App VG - Add or remove volumes panel, select volumes to add to the App VG or remove from the App VG, and click Next.
  5. In the Modify App VG - Manage IO Thresholds panel, specify a new Maximum IOPS value if required.
  6. In the Modify App VG - Summary panel, review the summary of proposed App VG modifications, and click Finish.
  7. In the Modify App VG - Result panel, review the results, and click OK.
