OK. Ikorolev. I will try to post the result of those mentioned commands soon. Thanks.

1. fcinfo work with adapters witch have sun-firmware only.
2. If your hba do not in sun compatible list (search in sunsolve.sun.com) - it wouldn't work.
3. if you plugin adapter from qligic (jni, emulecs and so on) with vendor firmware - you need install dirvers form this vendor and configure hba with help of utilites this vendor. but this hba (and all disk array) wouldn't be seen in fcinfo, cfgadm and so on.

Below are results.

Thanks Ikorolev. No wonder..
I don't have the information from the server which fcinfo works. That server is configured with Sun Leadville driver, and the rest do not.
Again, Thanks. Y4.

frst thing , you should be able to probe from the ok prompt using probe-scsi-all
what do you get for
# luxadm -e port
#luxadm qlgc
#luxadm probe
??

*Last resolution, try this
It will force the link to reinitialize, using the Loop Initialization Primitive (LIP) sequence:
luxadm -e forcelip yourfibrechannelhbaport

incredible - luxadm only works on SFS-supported 2gb hbas and sun-branded 2gb hbas, correct?

Not true..
bash-3.00# luxadm qlgc

you have qlogic-adapters with sun-firmware (qlc). sun-branded...
