Identifying a Single Disk When There are a Large Number of Virtual Disks Presented to the Host (6930346)

If there is a large amount of single volume or multiple virtual disks presented to the host system, it might be difficult to identify the boot disk as seen by the host system BIOS.

Workaround

1. If your server module REM is a Sun Storage 6Gb SAS REM HBA (SGX-SAS6-REM-Z), do the following:

   1. Allow the system to boot to the HBA MPT BIOS.

   2. When prompted select Ctrl-C to enter the MPT BIOS.

   3. Select the IR HBA from the prompt and press enter.

   4. Select the correct Hard Disk that the OS will be used to load the OS.

   5. Press Alt+B to mark the list as the preferred boot device.

   6. Record the WWN (World Wide Name, also known as SAS ID) from the selected list.

   7. Save the setting and reboot the host system.

   8. Enter the server's system BIOS by pressing F2 during boot.

   9. Select the appropriate boot disk in the Drive Priority list.

   10. Save the settings and reboot the host system.

   11. Load the appropriate OS and identify the boot disk by the recorded WWN.

2. If your server module REM is a Sun Storage 6Gb SAS REM RAID HBA (SGX-SAS6-R-REM-Z), do the following:

   1. Allow the system to boot to the HBA WebBIOS Setup screen.

   2. When prompted select Ctrl-N to enter WebBIOS.

   3. Use the HBA WebBIOS set up to create the required RAID and Virtual Disk configuration as described in the MegaRAID HBA User's Guide.

   4. Record the Virtual Disk ID and WWN (World Wide Name, also known as SAS ID).

   5. Save the setting and reboot the host system.

   6. Enter the server's system BIOS by pressing F2 during boot.

   7. Select the appropriate boot disk in the Drive Priority list.

   8. Save the settings and reboot the host system.

   9. Load the appropriate OS and identify the boot disk by the recorded WWN.
