6.9.1 Changing the Topology
NOTE: Point-to-point and FC-AL topologies are supported on the LPe31000-series, LPe32000-series, and LPe35000-
series adapters.
By default, the LPe12000-series and LPe16000-series adapters use auto topology with loop first. If you want to use a
topology other than the default, you must change the topology setting before configuring boot devices. For FC-AL, each
adapter has a default AL_PA of 01 (hexadecimal).
The topology options available in LPe12000-series and LPe16000-series adapters are shown in Figure 46.
You can configure these items:
 Auto topology with loop first – default
 Auto topology with point-to-point first
 FC-AL
 Point-to-point
The topology options available in LPe31000-series, LPe32000-series, and LPe35000-series adapters are shown in
Figure 47.
NOTE: FC-AL is private loop only (direct-attach).
 Point-to-point
 FC-AL
To select the adapter topology, perform these steps:
1. From the adapter list (Figure 31), select the adapter whose topology you want to change and press Enter.
2. From the main configuration menu (Figure 32), select Configure HBA and Boot Parameters and press Enter.
3. In the Configure HBA and Boot Parameters window, navigate to Topology Selection and press Enter.
