PowerPath and OS Replication/Imaging
NEED HELP FAST!!!
I have a Windows 2003 R2 Server running SP2. It's a Dell 2950, Dual Quad Core, 16GB RAM, RAID-1 pair of internal 73GB SAS Drives. I have two Qlogic 2460 4GB PCI-E HBA's connected (in a redundant configuraiton) to a pair of 9513's which are ultimately attached to a DMX-4 backend.
Config stuff out of the way...I have 8 of these machines, all with the same HW config, that will participate in a Windows cluster. I have built one machine and got it exactly where i needed it in regards to configuration and applications, including the latest version of PowerPath for Windows. Note: this first server has never been zoned/masked with disk and ECC agents have NOT been installed either.
My intent here is to sysprep this build and then image this machine to the other 7 for rapid deployment. I am now being told that I can't do this because PowerPath assigns a unique ID to the machine (or HBA's) and it will screw up clustering. This is the first time i hear about this...but...my question is, is this really true? Do i need to remove/reinstall powerpath?
(Note: We have always used Clariion systems in the past. The attached cluster hosts ran powerpath but also has the navi software installed as well. We just purchased this DMX and these are the first hosts going on it)
My understanding is that PowerPath will automatically adjust for new HBA's it see's and assign unique psuedo ID's for volumes as they get assigned to the server. In other words, I do not believe there is a problem here, am I correct?
