Adding a Logical Volume From Existing Logical Drives

NOTE: Logical volumes are unsuited to some modern configurations such as Sun Cluster environments, and do not work in those configurations. Use logical drives instead.

NOTE: Before you can add a logical volume from existing logical drives, you must unmap the logical drives.

  1. Select the array that you want to configure.
  2. Choose Configuration > Custom Configure.
  3. NOTE: This selection is inactive unless you have selected a controller with available physical drives.

  4. Select Add LDs/LVs to the Current Configuration from the Custom Configuration Options window.

  5. Verify that the server and controller displayed at the top of the window are correct.

  6. Select Use existing LDs to create LVs.

  7. If you do not see any logical drives listed under Select disks for logical drive, the logical drives have not been unmapped and therefore are unavailable to select. You must unmap the logical drives first.

  8. Select a logical drive and click Add to LV.
  9. When you have finished adding logical drives to the logical volume, to create another logical volume or an individual logical drive, click Commit LV.
  10. When you have finished creating logical volumes and do not want to create an individual logical drive, click Commit.

    NOTE: When you have finished creating logical volumes and want to exit the New Configuration window, if you accidentally click Commit LV instead of Commit, you will have to create another logical drive; otherwise, you have to click Cancel and configure the logical volume again.

  11. (HP-UX OS only) To ensure that the environment is stable and accurate after making configuration changes, you need to run the ioscan -fnC disk command.

    NOTE: If you used System Administrator Manager (SAM) to unmount the file system, make sure it is closed before running the ioscan -fnC disk command.

  12. (IBM AIX OS only). To ensure that the environment is stable and accurate after making configuration changes, you need to update the Object Data Manager (ODM) as explained in Updating the Object Data Manager.
