sorry for posting this in the Linux group, but I was not able to find a place to ask my question related to Powerpath on Windows...
My problem:
I have installed 2 Emulex LP 10000 cards in a Windows 2003 server, with driver version 5.1.20.3. Windows detects the cards, and they are installed correctly. I can even see disks in the windows disk manager. Powerpath (version 4.4.1.65)however, refuses to detect the Emulex cards
Has anyone an idea what the problem might be? I'm an experienced Windows admin, but have little experience with powerpath and (Emulex) fibercards.
welcome to forums. PowerPath will not display your adapters until after you present some LUNs from your array. As soon you as present LUNs from the array you will need to reboot the system (i have never had any luck with PowerPath detecting new LUNs on the fly) and when the system comes back up, your LUNs and HBAs should be listed in PowerPath GUI.
Funny, I rarely have to reboot Windows to get PowerPath recognizing new LUNs. Usually it is just when I'm cleaning up old ones that I have to reboot to get rid of old paths. Sometimes nothing else works (e.g. powermt check).
There really is a big difference between the two versions of the OS. I just did an online expansion today of a server using terminal services. It was nothing. Upgrade man, that OS is 8 years already! It doesn't get better with age
Tons better, especially with SP1 and above with at least PP 5.0. Like Allen I almost never have to reboot a server to get LUNs or additional paths to appear. Win2k3 is much better than Win2k was on dynamic changes to the OS like drive and network changes.
I haven't had any problems with the process on a cluster that I can recall. I am confirming this on my two-node lab cluster running W2k3 x64 SP1 and PP 5.1 and SQL2k. Will post the results in the morning.
