Running NNMi Outside HA with the Existing Database

If you want to run NNMi outside HA on any node with the existing database, follow these steps:

  1. On the active node (if one still exists), ensure that NNMi is not running:

    ovstop

    Alternatively, check the status of the ovspmd process by using Task Manager (Windows) or the ps command (Linux).

  2. On the current node (where you want to run NNMi outside HA), verify that NNMi is not running:

    ovstop

    Caution To prevent data corruption, make sure that no instance of NNMi is running and accessing the shared disk.

  3. (Linux only) Activate the disk group, for example:

    vgchange -a e <disk_group>
  4. Use the appropriate operating system commands to mount the shared disk. For example:

    • Windows: Use Server Manager—>Disk Management.
    • Linux: mount /dev/vgnnm/lvnnm /nnmmount
  5. Copy the NNMi files from the shared disk to the local disk:

    • Windows:

      %NnmInstallDir%\misc\nnm\ha\nnmhadisk.ovpl NNM -from <HA_mount_point>
    • Linux:

      $NnmInstallDir/misc/nnm/ha/nnmhadisk.ovpl NNM -from <HA_mount_point>
  6. Use the appropriate operating system commands to unmount the shared disk. For example:

    • Windows: Use Windows Explorer.
    • Linux: umount /nnmmount
  7. (Linux only) Deactivate the disk group, for example:

    vgchange -a n <disk_group>
  8. Obtain and install the permanent production license keys for the physical IP address of this NNMi management server as described in Apply Licensesthe "Licensing NNMi" chapter in the NNMi Deployment Reference.
  9. Start NNMi:

    ovstart -c

    NNMi is now running with a copy of the database that was formerly used by the NNMi HA resource group. Manually remove from the NNMi configuration any nodes that you do not want to manage from this NNMi management server.
