I've been using 5.1 on Win2K3 with no issues. Was this an isolated incident or did you try multiple hosts?

Also, are you running multiple HBAs? Is the PowerPath license installed?

Perhaps some weird combo of HBA / firmware / Flare code ? I don't know.
I'm running PP51 as well on Win2k3 without probs.

Run an EMCRPTS and upload the zipfile to Home > Support > Product and Diagnostic Tools > Environment Analysis Tools > Host Environment Analysis Tool (HEAT) to get hints and tips about possible patches and / or upgrades.

customers do not have access to HEAT (unfortunatelly), i have to always ask my CE to run them through HEAT for me.

Since March 10 HEAT is available on Powerlink for me. Now I'm a partner, so I have access, but indeed: when I switch into customer mode, it's gone.....

Right, quit teasing us with those partner only tools

Sasamir,
I have not had any issues with PP5.1, and in fact have been trying to get all my hosts on it as it seems to be very stable and handles the administrative addition and removal of paths quite well.

Did you have any eFixes installed for the previous version of PP when you installed 5.1? Leaving eFixes in place can cause problems for the new product.

Sorry.... I really thought it was publically available since a few days.....

i wish it was ...it would be nice for customer to upload a bunch of grabs and be able verify versions themselves ( I am hoping PowerLink people are reading this thread )

You could always fill out an enhancement request for EMC to make HEAT available

Enhancement request process is like "black hole" ..things go in but never come out.

hey Rob ..since you have access to HEAT now ..can i send my grab files to you ? Even though you are in Netherlands you are still easier to reach then my local CE

i am just kidding man
