Found the problem for the thing I posted last night!
If I comment out the CPQSHD.CDM from the STARTUP.NCF file and let SCSIHD.CDM perform those duties, the partitions are correctly read and usable. The version of CPQSHD.CDM I was using was version 2.02 dated mid-April of 2004. So far as I can tell, that's the latest. But now that node is working correctly.
Now to figure out the NetStorage thing.
