Qlogic hba driver: FC Port information format

Hello, experts !

Could any one point to what is the format of the qla drive entry in the /proc/scsi directory:

FC Port Information:
scsi-qla1-port-0=50060160bce02a1c:  500601623ce02a1c:161f00:81;

I need to know what two last fields mean, please

>> 161f00:81

what is "161f00"
and what is "81"

Thanks a lot in advance !

161f00 is the FCID - it's assigned by the FC fabric (SAN switch in this case).

81 is probably the LUN number - but that's a guess.
It looks like you're connected to a Symmetrix or DMX, so I'd be moderately confident in the guess that 81 is the LUN

This could be it, do you have a reference to the format, please ?

Is there a LUN number 129?
there is no lun 129
Ok, found it in the source code. 81 is loop id...

Thanks for your help, meyersd !

No worries. Glad I could help.
