
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.)
