Enable or Disable Individual Devices (+ Advanced )
This option applies only to arbitrated loop (FC-AL). Default is enabled for each device.
Each device can be enabled or disabled by the user. The maximum number of devices
(including LUNs) that can be displayed in the device menu is 99 per adapter.
If a change is made to the boot device in the Change BIOS Boot Device/Display All
Adapters menu, the user must check this menu to verify that the new boot device is enabled.
This menu option must be updated to reflect any hardware configuration changes.
Change PLOGI Retry Timer (+ Advanced )
This menu is used to set the interval for the PLOGI (port log in) Retry Timer. This option is
especially useful for Tachyon-based RAID arrays. Under very rare occasion, a Tachyon-
based RAID array will reset itself and the port will go off line temporarily in the loop. When
the port comes to life, the PLOGI retry interval scans the loop to discover this device.
The time it takes for one PLOGI to scan the whole loop (if 126 ALPA are on the loop) is
shown below:
l
50 msec will take 5 to 6 seconds.
l
100 msec will take 12 seconds.
l
200 msec will take 22 seconds.
The default is 0 (no retry); other options are 50, 100 and 200 milliseconds.
Topology Selections (+ Advanced )
Use this option to select the topology for the host adapter. Choose 1 for arbitrated loop (FC-
AL) and 2 for fabric point to point. The default is FC-AL
Fabric D_ID and WWPN section (+ Advanced )
This applies to fabric point to point topology only.
Fabric destination identifier (D_ID) indicates the address identifier of the N_Port.
A list of devices will be displayed by a Name Server Inquiry, which contains a list of all port
identifiers. By default, the first successful D_ID returned from a Name Server Inquiry will
be the boot device.
A dialog box appears with these choices.
D_ID and WWPN
. D_ID and WWPN are checked to see if they are also in the BIOS
region 8 area. If they are the same, boot occurs.
