Using The Alpha Console Wwidmgr -Show Adapter And -Set Adapter Commands; Caution - HP StorageWorks FCA2684DC Installation Manual

Using the Alpha Console wwidmgr -show adapter and
-set adapter commands
With Alpha Console v6.7 and higher, you can set the HBA to run in either Fiber
Channel Arbitrated Loop (FC-AL) mode or in Fabric (Switch) mode. By default,
the console assumes a fabric topology. When configuring the HBA, keep the
following considerations in mind:
Access the wwidmgr manual as follows for detailed information on the wwidmgr

Guide
The wwidmgr -set adapter command stores the selected topology into
the NVRAM storage on the HBA. If you move the HBA from one Alpha
Server to another, this setting stays with the HBA. Alpha Console v6.7 and
higher is required to support the FCA2684/FCA2684DC.
An FC-AL loop setting is a valid setting in Alpha Console v6.7, however, that
setting prompts the console driver not to run.

Caution:

If you connect an HBA to a switch using an FC-AL loop setting, the
results are unpredictable. The same is true for setting an HBA in fabric mode.
