• 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.
• 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.)
Note: The default topology is auto topology with loop first. Change this topology setting, if
necessary, before configuring boot devices.
