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

8 64-bit Fibre Channel Host Bus Adapter Release Notes for Tru64 UNIX and OpenVMS
In Figure 1, note the warning message “Nvram Read Failed.” This indicates
that the NVRAM on the HBA has not been initialized and formatted. This is
expected and can be corrected by issuing a –SET ADAPTER command as
described in the next section.

Figure 2. –SHOW ADAPTER display
Figure 2 shows a display from WWIDMGR -SHOW ADAPTER where there
are two HBAs in the system. See the following for a detailed look at a line
item:
[0] kgpsaa0.0.0.4.6 1000-0000-c921-05ab fabric fabric
■ [0] − Item Number. The bracketed value is used as a parameter to the
–item qualifier in the WWIDMGR -SET ADAPTER command. You
can select which HBA to configure by its item number. An item
number of 9999 selects all HBAs.
■ Kgpsaa0.0.0.4.6 − Adapter Mnemonic. Error messages and displays use
this identifier.
■ 1000-0000-c920-05ab − WWN of the HBA. This value is used to
identify the HBA to other nodes on the fibre channel link.
■ Fabric − Current Topology. This value is either fabric or loop. It
indicates the mode in which the HBA is operating currently, during this
WWIDMGR session. The current mode in which the HBA is running is
not altered during a WWIDMGR session.
■ Fabric − Next Topology. This value can be fabric, loop, or unavail. It
indicates the topology setting that is in the HBA’s NVRAM. An unavail
setting indicates the NVRAM is not formatted, a condition corrected by
a –SET ADAPTER command. A setting of fabric or loop indicates how
the HBA is configured the next time the system is initialized.
