To take advantage of the SAN boot feature on an Oracle SPARC host, you
must appropriately configure the HBA.
Before you begin
Before you configure the HBA, ensure that you already completed the following 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:
www.ibm.com/support
About this task
To configure
the HBA for SAN boot, use the following steps:
Procedure
- Change to the OpenBoot prompt. For example, you might type in a command similar to the following command: shutdown
-i0 -g0 -y
- At the OK prompt, type setenv auto-boot? false. This command specifies that the system does not restart after a power failure or after you use
the reset command.
- Type setenv use-nvramrc? true to
enable script interpretation.
- Type reset-all to
clear the system's
registers.
- 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.
- 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/JNI,FCR@1"
select-dev
Note: There is a space between the opening quotation mark and the forward
slash.
- Type set-pconfig.
- Type set-speed.
- Run probe-scsi-all and note the
WWPN associated with the boot volume.
- Type set-bootp-wwn and
enter the
WWPN found in the previous step.
- Type set-nvp-valid and
type FF as
the offset when prompted.
- Type reset-all.
- Type boot vx-disk –rv,
where disk is the name of your boot disk.
