Install the HP fibrechannel utils and run: # /opt/hp/hp_fibreutils/adapter_info

Which comes from this package:
ftp://ftp.hp.com/pub/softlib/software4/COL4635/co-19556-2/fibreutils-1.9.0-2.linux.i386.rpm

(Your mileage may differ, as i run RHES3 on a BL20p G3 server)

Hi Otong,

Yes, HP_FibreChannelUtilities.rpm is a nice suite of tools, however I am almost certain they are not bug free as experience has proven at our site, e.g. try detecting LUNs online on Linux with lssd or probe-luns..!! You would find more support for my previous statement on HP ITRC Forum details - a search would reveal similiar discussions on the HP FC Utilities rpm.

Assuming, you have Qlogic FCAs and their Qlogic drivers installed, to get the FCA WWNs, you could just run the following command:

cat /proc/scsi/qla2300/0
To get detailed info including FCA WWN on the first FCA
cat /proc/scsi/qla2300/1
To get detailed info including FCA WWN on the second FCA

Hope, it helps and consider assigning points to the responses if they are of any help to you.

Regards,
Saket.
