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:
Restart the Exalytics Machine using Integrated Lights Out Manager (ILOM).
Press Ctrl+Y and enter RAID CLI (Command Line Interface) as the Exalytics Machine is restarting.
Note:
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.
Enter the following MegaRAID command to delete the existing RAID configuration:
# -CfgLdDel -LALL -a0
Enter the following command to restore the RAID1 partition to an Exalytics deployment:
# -CfgLdAdd -r1[252:0, 252:1] WB Direct NoCachedBadBBU -a0
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
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.
