So this was an interesting exercise I had the other day on one of our HP-UX servers that took me quite a bit of time to research. Which of course makes it possible good blogging material because along the way there are useful commands for fiber channel discovery on HP-UX. Which incidentally makes it possibly not good blogging material.considering it’s on HP-UX. Meaning this is probably a really small target audience here. (Anyone actually still using HP-UX out there? Seriously, I feel like that scene in “Sixteen Candles” when “The Donger” is trying to tell Jake that Samantha is actually at the church getting married. Jake: “Don’t Jerk me around man, what unix are you using?” Donger: “HP-UX” Jake: “What?” Donger: “We’re using HP-UX.

Yup, HP-UX is still out there alive and kicking. Hard to believe isn't it? So this was an interesting exercise I had the other day and from it I came up with some. HP-UX, the powerful HPE. Capable of simultaneous support for both version 4 and version 6 of the IP protocol. Internet and Networking Solution Tools. Flactunes Music. Get the initiator driver info. You may also refer to the English Version of this knowledge base article for up-to-date information.

We have HP PA-RISC servers running HP-UX” Jake: “HP-UX?” Donger:”HP-UX.” Jake: “HP-UX?” Donger: “Yeah! HP-UX.” **Door Slams** Jake: “HP-UX?” Donger (behind closed door): “Yeah! Geeeez” The HP-UX Problem I Am Having With Our Fiber Storage Short version: The HP-UX server was attached to the external fiber storage via a switch. There are multiple (2) fiber connections which means there are multiple paths to the storage (think: multiple ways to get home from work). External Fiber storage, in an effort to load balance, chooses “preferred paths” for each logical disk it presents to the storage.

So as an example, say logical disks 1 through 10 the storage manager will say “You use path A”. And then logical disks 11 through 20 the storage might say “You use path B”. The problem I am having: the logical disk does not stay on the path that the storage wants it to. Welcome Speech For Sunday School Program. It keeps bouncing between the preferred path and non-preferred path. Possible Solutions Off the top of my head I wasn’t sure but the things I figured I would need to look at: 1) There is an intermittent hardware/connectivity issue on the preferred path which is why it kept flapping 2) The preferred path is set on HP-UX is opposite of the preferred path designated by the storage 3) The load balancing is not set correctly for preferred path (perhaps it is set to round robin) Sponsored Links Restrictions Could not get access to the fiber switch.

I could get access to the HP-UX server itself and could also see the storage GUI (incidentally it was IBM Storage Manager Client 10 managing an external DS4000 series storage, and it was the Storage Manager Recovery Guru that would complain on-and-off as the LUN mapping kept changing from preferred path to non-preferred path) Typographical Conventions Bold: Command line prompts Bold Blue: Things you type Bold Red: Output on the screen to look for Let’s GO! I like to do a bit of fact finding first, to get my head wrapped around the environment. You have a very nice way of explaining; even a dummy can understand your explanation. I hope to interact with you sometimes once I replace my faulty fiber channel adapters on rp4440.
