Everything you wanted to know about your HBA but were afraid to ask!!!

Well, as usual I was provided with a remote access to our lab machines at the beginning of the project, but needed to collect a whole lot of information about the server during the course of the project.

One such piece of information was about the HBA on the RedHat Linux box that I was working on.

You can find all the information you need about the HBA under /sys/class/fc_host

[root@isvx7 host5]# pwd
/sys/class/fc_host

[root@isvx7 fc_host]# ls

[root@isvx7 host5]# ls
