11. Configuring Boot from an FC SAN

Configuring Advanced Settings (Boot from SAN)

260

If a boot device is present, the BIOS boots from it immediately.

If a boot device is not ready, the BIOS waits for the spinup delay and, for up

to three additional minutes, continues the boot scanning algorithm to find

another multi-boot device.

Note: The default topology is auto topology with loop first. Change this

topology setting, if necessary, before configuring boot devices.

If no boot devices have been defined and auto scan is enabled, then the BIOS

waits for five minutes before scanning for devices.

In a private loop, the BIOS attempts to boot from the lowest target AL_PA it

finds.

In an attached fabric, the BIOS attempts to boot from the first target found in

the NameServer data.

Enable environment variable – Sets the boot controller order if the system

supports the environment variable.

Enable auto boot sector – Automatically defines the boot sector of the target

disk for the migration boot process, which applies only to HP MSA1000 arrays.

If there is no partition on the target, the default boot sector format is 63 sectors.

Set Auto Scan – With auto scan enabled, the first device issues a Name Server

Inquiry. The boot device is the first DID, LUN 0, or not LUN 0 device returned,

depending on the option you select. Only this device is the boot device and it is

the only device exported to the Multi-boot menu. Auto Scan is available only if

none of the eight boot entries is configured to boot via DID or WWPN. Emulex

strongly recommends that you use the Configure Boot Devices menu to

configure eight boot entries for fabric point-to-point, public loop or private loop

configurations. Set to one of the following:

Disabled (default)

Any First Device

First LUN 0 Device

First non-LUN 0 Device

Set the PLOGI Retry Timer – Sets the interval for the PLOGI (port log in) retry

timer. This option is especially useful for Tachyon-based RAID arrays. Under

very rare occasions, a Tachyon-based RAID array resets itself and the port goes

offline temporarily in the loop. When the port comes to life, the PLOGI retry

interval scans the loop to discover this device. This default setting is None (0

msec). Set to one of the following:

None (default)

50 ms

100 ms

200 ms

Type the Default AL_PA number – It has a range of 00-EF (default=0). Changes

the AL_PA (Arbitrated Loop Physical Address) of the selected adapter. (Not

available for OneConnect adapters.)
