Question: how to find wwpn in rhel?
Answer: If you downloaded a QLogic adapter from the QLogic website instead of using the default version that is included with RHEL, to find the WWPN run the cat /proc/scsi/ adapter_type / n command, where adapter_type is the host adapter type (for example, qla2 xxx or qla2300 ), and n is the host adapter number for your card.
