HELP (after XSAN controller crash files are not accessible)

Question

Hi,
We are having a major issue with one of our XSAN setups. During my breah one of the Xsan controller crashed and burned. So a college that to resuce it by rebuilding the contoller and adding the Luns to the Xsan volume.
The files are not showing up but they are still there when doing a data recovery scan.
So where I Need help with (never done this before) to get the files back. What would be next steps to get the data back?
Oh yeah, I will veryfy this today but I think the LUNS have the same identifiers and LUN ID asigned as the previous controller settings.
This Xsan setup is made out of Mac Pro Mountain Lion Xsan 3.0 (controller), two Promise Vtrak E-Class Raids and one Sandbox.
Appreciate any help thanks!
