Activating LSI RAID Volumes

When you need to activate an LSI RAID volume, you must temporarily remove the path through a SAS-NEM module in slot NEM 1.

This is required to make RAID volumes return with the same target ID that they had previously.


Activating LSI RAID Volumes

procedure icon  To Do Before Activating an LSI RAID Volume:

  1. Make sure that there is a SAS-NEM in slot NEM 0 and that it is functioning properly (the Fault LED is off).



    caution icon

    Caution - Make sure that multipathing at the OS level is enabled on all server blades that remain active in the chassis before you execute step 2. This ensures that the primary path to disks is not lost, which can cause an OS panic. For servers running Windows 2003, which does not support multipathing, shut down IO to all disks on the disk module that are not in hardware RAID volumes.



  2. Unplug the Multi-Fabric NEM in slot NEM 1 if there is one.



    Note - If you have a plain NEM, without SAS capability, in slot NEM 1 you can leave it there.





    caution icon

    Caution - Unplugging one SAS-NEM causes the loss of all secondary network connections and the secondary paths to SAS disks.



    Activate the RAID volumes by following one of these procedures:

    When you have finished activating the RAID volumes, plug the SAS-NEM back into slot NEM 1, if you previously unplugged it.

The LSI RAID configuration utility that is entered from the server’s BIOS is valid for all x64 server blades and all supported operating systems.

  1. Power-cycle your server module. The BIOS screen appears. Watch for the LSI Logic Corp. screen, soon after the opening screen.

  2. When the BIOS screen shows the LSI Logic Corp. message, press Ctrl-C to start the LSI Logic Configuration Utility.

    The first screen of the utility appears after a short delay.

  3. With the LSI 1068E adapter highlighted in the first screen, press Enter.

    The main screen of the utility opens.

  4. Use the arrow keys to select RAID Properties and press Enter.

    If you have only one array, you get a new screen with a View Existing Array option.

  5. With View Existing Array highlighted, press Enter.

    The View Array screen appears.



    Note - If you have two RAID arrays (volumes) you come directly to this View Array screen when you select and enter RAID Properties in Step 4.



  6. With Manage Array highlighted, press Enter.

  7. Use the arrow keys to select Activate Array and press Enter.

  8. Return to the View Existing Array screen and press Alt + N to select your other array (if there is one)

  9. Repeat steps 6 and 7 for your second array (volume), if there is one.

  10. Exit the LSI RAID configuration utility by pressing Esc repeatedly to go back screen by screen until you can continue the boot process.

  1. Go to the OBP prompt.

  2. At the command line, set the auto-boot? and fcode-debug? variables to false and reset the system.

    ok setenv auto-boot? false

    auto-boot? = false

    ok setenv fcode-debug? true

    fcode-debug? = true

    ok reset-all

  3. Find the path to the controller.

    ok show-disks

    a) /pci@0/pci@0/pci@2/LSILogic,sas@0/disk

    b) /pci@0/pci@0/pci@1/pci@0/usb@1,2/storage@1/disk

    q) NO SELECTION

    Enter Selection, q to quit: q

    ok



    Note - You are looking for the path to the controller. For the T6320 and T6340 blades it contains the phrase “LSILogic,sas@0”. For the T6300 blade, it contains the phrase “scsi@0“.



  4. Select the controller.

    ok select /pci@0/pci@0/pci@2/LSILogic,sas@0

  5. Show the volumes, looking for any that are inactive.

    ok show-volumes

  6. Activate the inactive volumes. Repeat the command to activate all inactive volumes. For example, to activate volume number 1 type:

    ok 1 activate-volume



    Note - There might be more than two inactive RAID volumes, but you cannot activate more than two.



  7. Deselect the controller.

    ok unselect-dev

  8. Set the auto-boot? and fcode-debug? variables to true and reset the system.

    ok setenv auto-boot? true

    auto-boot? = true

    ok setenv fcode-debug? true

    fcode-debug? = true

    ok reset-all
