Mutiple paths down one fibre card

I have attached a new server to our SAN and the ioscan shows mutiple paths to the HSV controllers through my A6795A card.

I presented one vdisk and securepath recognises the one disk with all the paths as you would expect.

Can anyone tell me why I can see so many ctl instances down one path on /dev/td0. The alternative controller on /dev/fcd0 has the one instance you would expect.

/dev/td0 is the A6795A
/dev/fcd0 is the combo card with 1Gb ether.

Cheers

Did you set the operating system type to HP-UX on your Host entry and reboot the server?

OS type is probably set to windows. If you will connect only HP-ux servers to this EVA, you can also change default OS offered by Command View so it will no longer show windows by default.

Ahh...Thank you gentlemen...

The switch had some old port based zone sets for what used to be a windows server and the default was also windows.

Thought I was going crazy....

Respect.
