Uninstalling the HP IMP for MOM 2000

If the HP IMP for MOM 2000 has been installed in a MOM 2005 environment, it must be removed before installing the HP Management Packs 1.3 for MOM 2005. Failure to do so can lead to duplicate event and group entries and inoperative functionality under MOM 2005.

The current architecture for MOM management packs does not allow for the easy removal of an imported management pack. HP has documented the following procedures to remove the graphical and database entries associated with the HP IMP for MOM 2000.

Several elements of the HP IMP for MOM 2000, such as computer groups, computer attributes, tasks, scripts, and views, can easily be deleted from the MOM administrator or operator console tree manually. The processing rules and other database elements that might link to outstanding alerts cannot be removed immediately.

NOTE: Database elements linked to outstanding alerts cannot be removed until MOM Database Grooming completes. By default, Database Grooming has a grace period of four days. You can verify this period by selecting Administration>Global Settings>Database Grooming. Database Grooming might take longer than the specified time to complete.

To uninstall the HP IMP for MOM 2000:

  1. Open the MOM Operator Console.
  2. Verify that no pending alerts are displayed, and exit the MOM Operator Console. Resolve any pending alert listed in the MOM 2005 Operator Console before proceeding to step 3.

    NOTE: See "HP IMP for MOM 200 data tables" for a complete list of the HP IMP for MOM 2000 components that must be manually deleted.

  3. Right-click each HP IMP subfolder under Computer Groups, and select Delete Computer Group.

    A confirmation window appears with options to delete subgroups under the Computer Groups folder. Because there are no subgroups under Computer Groups, leave the default options selected and click OK.

  4. Select the Computer Attributes folder.
  5. Right-click each HP Insight computer attribute, and select Delete.
  6. Right-click the top-level HP IMP Rule Groups folder, and select Delete.
  7. Select Delete the rule group and all child rule groups.

  13. Right-click HP Insight Management under the Public View folder, and select Delete.

After these steps have been completed and the HP IMP Rule Groups have been disabled and removed, the HP Management Packs 1.3 for MOM 2005 can be installed. Database Grooming does not need to complete before installing the HP Management Packs 1.3 for MOM 2005.
