PowerPath 5.5 MPIO Version 1.23
I have a Windows 2003 server that is currently connected to a Dell MD3000i iscsi enclosure. This is using the Microsoft Initiator 2.08 which in turn uses MPIO version 1.22. We are now attaching this server to our new VNX box so we can migrate the data. I need to install the PowerPath 5.5 software but when I start the installation, it throws an alert that I'm running MPIO version 1.22 and it needs to be updated to version 1.23. My fear is that if I select update, I will have issues with my existing iSCSi luns! This is my enterprise sql server that I really don't want to have issues on. Like I said, I need to have the server connected to both storage devices for the time being so the DBA can migrate all his databases over to the fiber channel storage on the VNX. Once he's done, I plan on removing the Dell device completely.
Can someone please help me out here? I need to get this going. Here is a screenshot of the message:

So I can just present a single path nativly without the power path software? Windows will just "see" it once the lun is presented to the server?

present single path from the VNX during the migration. When migration is complete, install PowerPath and configure multiple paths.

since you are on windows 2003 and running SQL, don't forget to align the partition with diskpart and set file allocation unit to 64k

Thank you! I'm going to try this next week. Hopefully, it goes as planned.

absolutely, you and your DBA need to sign off on the risk of running on single path during this migration period.
