Resetting RAID Configuration (Optional)

If you are on a virtual Exalytics virtualization and want to revert back to a nonvirtual Exalytics deployment, you must reset the RAID configuration by performing the following steps:

To reset RAID configuration:

  1. Restart the Exalytics Machine using Integrated Lights Out Manager (ILOM).
  2. Press Ctrl+Y and enter RAID CLI (Command Line Interface) as the Exalytics Machine is restarting.


    The "Copyright LSI Logic Corporation" displays during the restart sequence when it is possible to enter the RAID CLI. Observe the screen carefully as the message displays for a very short time. This avoids restarting the machine again.

  3. Enter the following MegaRAID command to delete the existing RAID configuration:

    # -CfgLdDel -LALL -a0

  4. Enter the following command to restore the RAID1 partition to an Exalytics deployment:

    # -CfgLdAdd -r1[252:0, 252:1] WB Direct NoCachedBadBBU -a0

  5. Enter the following command to create a RAID5 partition with the remaining drives:

    # -CfgLdAdd -r5[252:2, 252:3, 252:4, 252:5] WB Direct NoCachedBadBBU -a0

  6. In the left pane of the ILOM, expand Host Management, then select Power Control. In the Select Action list, select Power Cycle, then click Save.

    The Exalytics Machine restarts.
