3.5.Changing the Topology

3.Press the number corresponding to the PLOGI retry timer interval you want to use. The time it takes for one PLOGI to scan the whole loop (if 126 AL_PA are on the loop) is:

50 msec: 5 to 6 seconds per device.

100 msec: 12 seconds per device.

200 msec: 22 seconds per device.

4.Press x to exit the BIOS utility and reboot the system.

3.5.Changing the Topology

This option allows you to select the topology for the host adapter.

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

To select the host adapter topology, do the following:

1.Start the BIOS utility (see section 3.1, Starting the BIOS Utility, on page 3-1.) and select the desired HBA. Press 2 to configure the adapter.

2.Press 4 (Topology Selection). The screen to the right is displayed.

3.Press the number corresponding to the topology for the host adapter:

Press 1 for auto topology with loop first.

Press 2 for auto topology with point-to-point first.

Press 3 for FC-AL.

Press 4 for fabric point-to-point.

4.Press x to exit the BIOS utility and reboot the system.

3.6.Enabling and Disabling the Spinup Delay

This option allows you to enable or disable the spinup delay.

The default setting is disabled.

If at least one boot device has been defined, and the spinup delay is enabled, the BIOS searches for the first available boot device. 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.

If no boot devices have been defined, and auto scan is enabled, then the BIOS waits for five minutes before scanning for devices. In the private loop case, it attempts to boot from the lowest target AL_PA it finds. In the fabric attached case, it attempts to boot from the first target found in the NameServer data.

To enable or disable the spinup delay, do the following:

1.Start the BIOS utility (see section 3.1, Starting the BIOS Utility, on page 3-1.) and select the desired HBA. Press 2 to configure the adapter.
