5.1.1.4.4 Reconfiguring Existing RAID Configuration on an X6-4 and X5-4 Exalytics Machine

The X5-4 Exalytics Machine comprises six hard drives, each having a capacity of 1.2 TB, and the X6-4 Exalytics Machine comprises six hard drives, each having a capacity of 2.4 TB. Two drives are configured as RAID1 and four drives are configured as RAID5. To optimize the use of the disk space, you must reconfigure the RAID1 and RAID5 configurations on the Exalytics Machine. Reconfigure RAID1 so that it consists of two virtual drives and RAID5 consists of the remaining drives.

To reconfigure existing RAID configurations on the X6-4 and X5-4 Exalytics Machine:

1. Restart the Exalytics Machine using Integrated Lights Out Manager (ILOM).

2. At the prompt, Press Ctrl><R> for WebBIOS... , press Ctrl+Y to access the LSI MegaRAID utility as the Exalytics Machine is restarting.

   Note:

   Observe the screen carefully as the Press Ctrl><R> for WebBIOS... .message displays for a very short time. This avoids restarting the machine again.

   The Virtual Drive Management screen is displayed.

3. Delete the existing RAID configuration, by performing the following actions:

   1. Select the first virtual drive and Press F2.

   2. Select Delete VD.

   3. At the prompt, Press Yes.

   4. Repeat the above steps (a to c) to delete the second virtual drive.

4. Create a RAID1 partition of two virtual drive, by performing the following actions:

   1. On the Virtual Drive Management screen, Press F2.

   2. Select Create Virtual Drive.

      The Create New VD screen is displayed.

   3. In the RAID Level drop down field, select RAID1.

   5. Select Advanced.

      The Create Virtual Drive-Advanced screen is displayed.

   6. Select Initialize, and then select OK.

      The "Initialization complete on VD 0" message is displayed.

   7. Select OK.

      The Virtual Drive Management screen displays the 100 GB virtual disk created.

   8. To create the second virtual drive, select Drive Group: 0, RAID1, press F2, and then select Add New VD.

   9. In the RAID Level drop down field, select RAID1.

   10. Under Basic Settings, in the Size field, accept the default value, and select Advanced.

   11. Select Initialize, and then select OK.

       The "Initialization complete on VD 1" message is displayed.

   12. Select OK.

       The Virtual Drive Management screen displays the RAID1 partition created of two virtual drives.

5. Create a RAID5 partition with the remaining drives, by performing the following actions:

   1. On the Virtual Drive Management screen, select LSI MegaRAID, press F2, and then select Create Virtual Drive.

      The Create New VD screen is displayed.

   2. In the RAID Level drop down field, select RAID5.

   3. Select the four virtual drives (02, 03, 04, 05).

      Note:

      For each virtual drive, accept the default size of the drive.
