IBM Configuring the PLOGI Retry Timer for Optimal Performance

Change the PLOGI Retry Timer

This option allows you to set the interval for the PLOGI (port login) retry timer. This option is especially useful for Tachyon-based RAID arrays. Under very rare occasions, a Tachyon-based RAID array will reset itself and the port will go 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 No PLOGI Retry: 0 msec.

To set the interval for the PLOGI retry timer:

1.Start the BIOS utility and select the adapter.

2.When the main menu opens select 2, Configure This Adapter's Parameters. The adapter configuration menu is displayed (Figure 11).

3.Select 3, Change PLOGI Retry Timer (+Advanced Option+).

Figure 13: Change the PLOGI Retry Timer Screen

4.Select the PLOGI retry timer interval. The time it takes for one PLOGI to scan the whole loop (if

126 AL_PA are on the loop) is shown below:

•50 msec will take 5 to 6 seconds per device.

•100 msec will take 12 seconds per device.

•200 msec will take 22 seconds per device.

5.Press <x> to exit the BIOS utility and reboot the system.

Change 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:

1.Start the BIOS utility and select the adapter.

2.When the main menu opens select 2, Configure This Adapter's Parameters. The adapter configuration menu is displayed (Figure 11).
