I try to configure a brand new SAN configuration with RHEL 6.6. SAN team requested host wwn's for zoning, which I believe are individual hba's wwn's. Anyhow here is my scenario:
My hba's are dual port. But only one port is in use. So in total I have 3 hba's. and each of them are dual ports. Fiber cables are attached let's say port 0 of each hba.
I can use different tools and commands and find all wwn's. For 3 hba I have 6 wwn in total. But only 3 in use.
So how I can find which wwn is actually attached to SAN?
I also checked link status but all look as "down" (link_state).
