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.
item	adapter	WWN	Cur. Topo	Next Topo
pga0.0.0.3.1 - Nvram		read failed
[ 0]	pga0.0.0.3.1	1000-0000-c920-eda0	FABRIC	UNAVAIL
pgb0.0.0.4.0 - Nvram		read failed
[ 1]	pgb0.0.0.4.0	1000-0000-c920-da01	FABRIC	UNAVAIL
pgc0.0.0.5.1 - Nvram		read failed.
[ 2]	pgc0.0.0.5.1	1000-0000-c920-cd9c	FABRIC	UNAVAIL

[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).
