It looks like your server is not part of SAN yet. What switches/Disk Array are you using in the SAN topology?
Can you login to the SAN switch and see if you can identify the server and storage?
Also whats the output of ioscan?

"...even the internal disks are not shown ..."

Please run "ioscan -fn" and post the result.

You could use the "ioscan -funC disk" ,which will show full listing of the devices in the system.Alternativly you can get much formatted output from "sam" or "cstm" as well.
