P00>>> boot
If you have initialized and booted the system, then shut down the
system and try to use the wwidmgr utility, you may be prevented
from doing so. If you receive the following error, initialize the
system and retry the wwidmgr command:
P00>>> wwidmgr -show adapter
wwidmgr available only prior to booting.
Reinit system and try again.
P00>>> init

P00>>> wwidmgr -show adapter

For more information on the wwidmgr utility, see the Wwidmgr
User’s Manual which is on the Alpha Systems Firmware Update
CD-ROM in the DOC directory.
Use the worldwide ID manager to show all KGPSA adapters:
P00>>> wwidmgr -show adapter
Link is down.

[9999] All of the above.
The Link is down message indicates that one of the adapters is not
available, probably due to its not being plugged into a switch. The warning
message Nvram read failed indicates that the KGPSA NVRAM has not
been initialized and formatted. The next topology will always be UNAVAIL
for the host bus adapter that has an unformatted NVRAM. Both messages
are benign and can be ignored for the fabric mode of operation. To correct
the Nvram read failed situation, use the wwidmgr -set adapter
command.
The previous display shows that all three KGPSA host bus adapters are set
for fabric topology as the current topology, the default. When operating in
a fabric, if the current topology is FABRIC, it does not matter if the next
topology is Unavail, or that the NVRAM is not formatted (Nvram read
failed).
