Just a quick note since I hear of people running into this issue all the time.

I’m unsure if this is an HBA firmware issue, or if it ‘works as expected’, but when plugging a Fiber cable into an HBA while it’s attached to an LPAR, you will not get a link immediately. Actually, this isn’t even LPAR specific, I have had this happen with physical systems as well.
From past experiences, you’ll have to rmdev -dl the fcs0,fcnet0,fscsi0,etc and run cfgmgr to bring the device back in. This seems to perform some sort of virtual power off/on type of situation, then will reconfigure the device and it will have a link. I’m not sure if this is just the environment I’m working with or not, but it happens every time a cable is plugged in while the system is live!
