Configuring an Emulex HBA for SAN boot

Edit online

To take advantage of the SAN boot feature with an Emulex host bus adapter (HBA) on an Oracle SPARC host, you must configure the HBA.

Before you begin

Before you configure the Emulex HBA, ensure that you complete these actions:
  • Configured the HBA for static port binding.
  • Configured and mapped the volume that serves as the SAN boot disk.
  • Configured the LUNs for use with VERITAS Volume Manager with DMP.
  • Mirrored the boot volume onto the discovered LUNs.
  • Installed the correct level of FCode on your HBA. To find the correct level, see the supported hardware list at the following website:

About this task

To configure the Emulex HBA for SAN boot, complete the following steps:

Procedure

  1. Start the lputil utility (/usr/sbin/lpfc/lputil).
  2. At the main menu, enter 3 (Firmware Maintenance).
  3. At the firmware maintenance menu, enter 6 (Boot BIOS Maintenance). If the boot code is disabled, press 1 to enable it.
  4. Change to the OpenBoot prompt.
    For example, you might enter a command that is similar to the following command: 
    shutdown -i0 -g0 -y
    Note: An ok displays for the prompt when you are at the OpenBoot prompt.
  5. Type setenv auto-boot? false.
    This command specifies that the system will not reboot after a power failure or after you use the reset command.
  6. Type setenv use-nvramrc? true to enable script interpretation.
  7. Type reset-all to clear the system's registers.
  8. Type devalias to identify the device aliases and the associated paths of devices that are connected to the system. Note the device alias of the HBA, which presents your SAN boot volume.
  9. Select the HBA device by typing "/devicestring" select-dev, where /devicestring is the device alias string that you wrote down.
    The following command is an example:
    " /pci@1f,2000/lpfc@1" select-dev
    Note: A space exists between the opening quotation mark and the forward slash.
  10. Type set-default-mode to reset the HBA parameters.
  11. Type set-ptp to set the HBA to point mode.
  12. Run probe-scsi-all. Note the WWPN associated with the boot volume, along with its LUN and target IDs. This information is required for the next step.
  13. Type WWPN yourwwpn lun targetid, where yourwwpn is the WWPN associated with the boot volume, lun is the associated LUN, and targetid is the associated target ID.
    The following command is an example:
    WWPN 5005076803041234 0 3
  14. Type reset-all.
  15. Type boot vx-disk –rv, where disk is the name of your boot disk.
