Intel® RAID Controller SRCU42X
Creation RAID 10 with SCRU42X RAID controller

Solution:

Configure the RAID Controller

  1. Power on the server.
  2. After POST, the message "Press <Ctrl><G> to enter the RAID BIOS Console" displays. Press Ctrl+G immediately to start the RAID BIOS Console.
    Note There is approximately a 20-30 second delay before the BIOS Console displays.
  3. On the Adapter Selection screen, select the adapter to configure, and select Start.
  4. The View Config screen displays and shows the current configuration. The Physical Drive window should show at least four drives in the Ready state, and the Logical Drive window should show no logical drives.
  5. Select Adapter Properties from the Main menu (on the left side of the screen). The Adapter Properties screen displays.
    1. Ensure that Fast Initialization is Enabled.
    2. Select Submit to save changes and to return to the View Config screen.

Configure the RAID 10 array

  1. Select Configuration Wizard from the Main menu.
  2. Choose New Configuration, then select Next.
  3. Click Yes to acknowledge that all existing data will be deleted and to continue with the new array configuration.
  4. Choose Custom Configuration. Select Next. The Array Definition screen displays.
  5. From the Physical Drives menu (on the left side of the screen), highlight the first two drives (ID0 and ID1) to add them to the array. To highlight more than one drive, hold down <CTRL> while selecting the drives.
  6. Select Accept Array. The new array is represented as Array 1 in the Arrays window on the right side of the screen. The storage space available to create the RAID logical drive displays adjacent to the array icon.
  7. To create a second array, repeat steps 5 and 6 using the next two ready drives (ID2 and ID3).  The new array is represented as Array 2 in the Arrays window on the right side of the screen.
  8. Select Next. The Logical Drive Definition screen displays.
  9. Highlight both arrays in the Arrays window. To highlight more than one array, hold down <CTRL> while selecting the arrays.
  10. Set RAID Level to RAID 1.
    Note Even though RAID 1 is selected, this array is a RAID 10 array because spanning will be enabled.
  11. Set Stripe Size.
  12. Ensure the Write Policy is set to Write Thru.
    Note To improve performance, the Intel RAID Controller SRCU42X uses onboard cache memory to store commonly accessed data. Although write-back policy is supported, it should not be used on a production server unless a battery backup unit is installed and the battery is fully charged. The battery backup unit is not shipped from the manufacturer in a charged condition. If the system power should suddenly fail while the battery is uncharged or in a partially charged state, all of the data in the cache could be lost and data corruption could occur. For this reason, use write-through policy until the battery unit is fully charged.
  13. Set Span to Enable.
  14. Set Select Size to N, where N = 2 X (capacity of the smallest RAID 1 array). For example, if the displayed capacity of each RAID 1 array is 35002 MB, then enter 70004.
    Note Because spanning is enabled, the system by default will use the correct size, regardless of the number that you enter in the Select Size data entry box.
  15. Select Accept. The new logical drive configuration displays in the Arrays window.
  16. Select Next to advance to the Configuration Preview screen. This screen shows one logical drive spanning two RAID 1 arrays.
  17. Select Accept to save the configuration. The configuration is saved to disk and NVRAM. To confirm the operation, select Yes.
  18. The following message is displayed: "Do you want to initialize the new logical drive(s)?" Select Yes.
  19. When initialization is complete, the Logical Drives screen displays. Select the Home icon.
  20. Select Exit and Yes to exit the BIOS Console.
  21. Shut down your server.
