You have discovered a bug in the xCAT noderange. What xCAT does in that case is interpolate that into an expanded view, so mei[1-6]1xt Gets expanded to: mei11xt-mei61xt Before evaluation (with obvious problem).
Note that while I wasn't aware of this specific issue, the confluent noderange actually does the right thing: # nodelist mei[1-5]1xt mei11xt mei21xt mei31xt mei41xt mei51xt It is suboptimal, but you could do nodels mei[1,2,3,4,5,6]1xt which would work. There are a few limitations in the [] syntax as implemented by Noderange.pm in xCAT today.
