Hi Basheer,

Once you install the HP supplied Qlogic FCA driver, you should be able to just run the commands "cat /proc/scsi/qla2300/0" - for the first FCA and the "cat /proc/scsi/qla2300/1" - for the second FCA. These commands will provide you heaps of information about your FCAs such as FCA Drivers, WWNs, Topology, settings, etc.

Alternatively, the driver version is also registered in the Name Server of the SAN Fabrics. So against the switch ports to which your Linux server's FCAs are connected - you should be able to see the driver version - FCA WWNs, etc.

"lspci" is another command to list just the pci option cards installed on your server - you might find it handy too.

...if you use Secure Path for Linux, then "spmgr display" commands will also provide you heaps of information about the FCAs....something along the lines of "spmgr display -a ADAPTER_INSTANCE"....this one is off the top of my head ..check for exact syntax.

Hope, this answers your query.

Cheers,
Saket.

You can also download the SANsurfer free software from Qlogic:

http://www.qlogic.com/products/sanmgmnt/sansurfer_tool.asp

This is a GUI.
There is also a CLI component .

Sansurfer....yes is a nice tool ...but remember if there is a native OS level tool to provide you the info - why bother installing a seperate tool on each host - also if you intend to install the SanSurfer Manager running on one host - you still need to deploy the agents on all your hosts - if you have firewalls - allow appropriate ports to be opened - look after ongoing security/bug fixes patches for the agents as well as the SanSurfer Manager..now tell me if you would still call the overall management of this product "free"!! I am sure you have enough work of keeping your server OS, patch kits, service packs, etc, etc up-to-date - do you really want to take on another bit of task!

I would recommend a native OS level tool over any third party (regardless of whether its free or comes with a cost) tool any day - ofcourse if it does the job!

my 2 cents worth...
