Go to Qlogic's web page and check the driver section for EMC and locate your HBA by model number - then check that the driver is the one that you're using - the EMC drivers have the settings already setup - remember to also install the Microsoft hot fix for the drivers.  [URL]  glen
Hello,  i've successfully setup PowerPath on a Windows 2003 Server having a QLA2342 (dual port FC HBA). It manages 4 paths seen throug two fabrics. The CX3 is connected by 2 ports of each SP to the fabrics. I hope i've done right to setup the array failover mode to 1 (PNR). My tests where successfull that the LUN would automatically be trespassed if one path set fails (i've simply unzoned both paths to the SP where the LUN was bound), so i think i've done everything right. Or is it possibe/better to use ALUA mode for the Array? Now i've read in the documentation to take care about special HBA settings recommended by EMC, otherwise performance my be decreased. But i can't find any hints.
Do i need special settings for my QLA2342 in conjunction with PowerPath?
