My system is an Altix3000 running: (Linux sgialtix 2.4.21-sgi304r1 #1 SMP Sat Jan 29 22:43:29 PST 2005 ia64 ia64 ia64 GNU/Linux) (redhat-release=redhat-release-3AS-8.3). Which command do I use to list World Wide Name information of the QLA2300 HBA? I tried /proc/scsi and /proc/xscsi but I found nothing there. Thank you for your help.

What exactly are you asking here? – nhinkle Apr 10 '11 at 5:18
I have connected the SGI Altix3000 to an SGI Storage Box, to map LUN to the SGI server i need to have the WWN that's why im looking for the command to get the FC card info. – AlBouazizi Apr 10 '11 at 6:39

I use QLogic cards in Linux. For this I use:

cat /sys/class/fc_host/<host3>/port_name

The <host> entry is different for each FC processor and host.

Your FC switch will also show this value when you connect the ports.

I don't see /sys/class/fc_host what i see is scsi_host – AlBouazizi Apr 20 '11 at 5:12
@AlBouazizi, I was searching around... check the output of "/var/cluster/cxfs_client-scripts/cxfs-enumerate-wwns". Sorry I don't know Altix all that well... – Peter B Apr 28 '11 at 14:11
/var/cluster/: No such file or directory Thankk you for effort – AlBouazizi May 6 '11 at 5:54

now, it seems to be a fairly complex process. According to this its supposed to be in /proc/scsi, and you can pull out the port numbers with egrep.

What i was asking: i need to have the WWN of the Fibre Channel: QLogic Corp. QLA2300 64-bit FC-AL Adapter (rev 01). – AlBouazizi Apr 10 '11 at 6:36
Journeyman Geek, in /proc/ no scsi dir found- in /proc/xscsi found 2 files(dksc,scsi) and one dir ctrl with nothing is there. – AlBouazizi Apr 10 '11 at 6:43
