Chris, I don't agree with that. My memory is foggy because there are so many storage array vendors and their consoles are all different. I haven't run across one that doesn't let you enter WWPNs manually. It isn't always easy to find, and might be through a CLI, but it is always there.
So, I bet you have 2 options: enter them in some manual way drag and drop with the GUI as you have been advised Regards, Ray Higgs System z FCP Firmware Development Bld. 706, B42 2455 South Road Poughkeepsie, NY 12601 (845) 435-8666, T/L 295-8666 rayhi...@us.ibm.com Linux on 390 Port <LINUX-390@vm.marist.edu> wrote on 01/10/2014 12:38:25 PM: > From: "Will, Chris" <cw...@bcbsm.com> > To: LINUX-390@vm.marist.edu > Date: 01/10/2014 12:40 PM > Subject: Re: Question on WWPN WP > Sent by: Linux on 390 Port <LINUX-390@vm.marist.edu> > > Our issue is that z/VM and the zLinux guests have to be up and the > npiv channel logged in before the new NPIV WWPN can be zoned from > the SAN side.
