I finish installing a blade server with linux Red Hat version 5. How would I proceed now to identify the fiber channel cards. What command to use ?

If you install the Linux Fibre Channel Enablement Kit for RHEL 5.3/5.4 you will have access to tools like "hp_rescan" which will show you information on your Emulex or QLogic HBA's

The description for this link says QLogic, but the same file works for both QLogic and Emulex

I used the lspci command and there is no Fiber Channel card found, but the command report a lot of unknown devices.
I am using BL 460c G6, where can I get the drivers to download ?
Does it come with an embedded or prebuilt Fiber Channel card ?

What update version of RHEL5 are you running?

Which HBS mezzanine card do you have installed?

I installed the PSP and the FC HBAs were successfully discovered. I included them in the same zone as the EVA Storage and presented a LUN to the server.
Here is what follows:

[root@localhost scsi]# hp_rescan -a
Rescanning /sys/class/scsi_host/host1
Rescanning /sys/class/scsi_host/host2

How should I proceed ?

It's showing that it found and forced a rescan on 2 devices

Now you should be able to run fdisk or setup multipathing to access the LUNs you presented to the host

Thanks.
What should I do next to discover the EVA or the LUN that is presented to it.
