Validating or modifying a snapplan

Before creating a snapshot, it is necessary to validate your snapplan to make sure the information is correct and that the snapshot will succeed. Occasionally, you may also need to modify a snapplan. For example, you would need to modify your snapplan if you wanted to change the primary disk group that is included in the snapshot.

Prerequisites

  • You must be logged in as the DB2 database administrator.

  • A DCO log must be attached to the snapshot plex.

Usage notes

  • Each entry in the snapplan is a line in parameter=argument format.

To validate or modify a snapplan

  1. Click a specific snapplan in the object tree. (You may need to expand the tree view to find the icon.)

  2. Access the Validate/Modify Snapplan wizard.

    See Accessing FlashSnap tasks in the Java GUI.

    See Accessing database tasks in the Web GUI.

  3. In the Modify/Validate Snapplan wizard, correct the path and file name of the snapplan in the Snapplan file field. Then, click Next to continue.

  4. If you are modifying your snapplan, enter any new parameters that should be updated. You are not required to do anything if no changes are required.

    For more information regarding the snapplan parameters:

    See "Creating and Working with Snapplans Using dbed_vmchecksnap" in the Veritas Storage Foundation for DB2 Administrator's Guide.

  5. Click Validate to check that the settings have been configured correctly.

  6. At the confirmation prompt, click Yes to confirm that you want to validate the snapplan.

    If the snapplan was successfully validated, you will receive a confirmation message.

  7. To see the snapplan details, click the Show details checkbox. The snapplan details are displayed in the pop-up window.

    When you have finished reviewing them, click OK.
