64-Bit PCI to Fibre Channel Host Bus Adapter for Tru64 UNIX and OpenVMS - Release Notes (AV-RLLUA-TE)

64-Bit PCI to Fibre Channel Host Bus Adapter Release Notes for Tru64 UNIX and OpenVMS 7
WWIDMGR -SHOW ADAPTER / -SET
ADAPTER Commands
V5.6 SRM console and higher revisions have the capability of setting an HBA
to run in arbitrated loop mode or in fabric (switch) mode. If an HBA in loop
mode is connected to a switch, the results are unpredictable. The same is true
for an HBA in fabric mode that is connected to a loop. By default, the console
assumes a fabric topology. The SET ADAPTER command stores the selected
topology into the NVRAM storage on the HBA. If the HBA is moved from
one AlphaServer to another, this setting stays with the HBA. Console
Revision V5.6 or greater supports the FCAL (loop) topology. A setting of
loop is a valid setting in Console Revision V5.6, however, that setting prompts
the console driver not to run. What this means is once the HBA has been set to
loop topology, console commands such as show device or quick assign will
not display any HBA’s and their attached devices.
Refer to the WWIDGR manual at the following location for detailed
information on the –SHOW ADAPTER and –SET ADAPTER commands:

NOTE: On some systems , such as the GS140, in order for the –SHOW ADAPTER and –
SET ADAPTER commands to be accepted by the system, the console must first be set to
diagnostic mode (set mode diag). While on other systems such as the DS10, DS20 and
ES40 the set to diagnostic mode (set mode diag) is not required in order to enter the -
SHOW ADAPTER and -SET ADAPTER commands.
-SHOW ADAPTER Command
The HBA configuration can be displayed with the command (see Figures 1
and 2):
