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 first unmap the logical drives.

  1. Select the appropriate array.
  2. Select 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 the server and controller that are 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 a 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 are finished adding logical drives to the logical volume, to create another logical volume or an individual logical drive, click Commit LV.
  10. When you are finished creating logical volumes and do not want to create an individual logical drive, click Commit.

    NOTE: When you are 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 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 command.

  12. (IBM AIX OS only). To ensure 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 on an IBM AIX Host.
