May I ask what sort of SAN? Fibre Channel or iSCSI? Are there any access controls (such as EMC's Access Logix or zoning in the switch) in place to prevent multiple initiators connecting to a particular LUN?
SAN attachment mildly complicates things; I've seen some odd LUN reshuffling before, but it was an older FLARE than what I'm currently running on our Clariions and it was something that was a corner case but was fixed in a later NDU, and it had to do with Access Logix (I don't remember the Primus number right off, as it has been several years now).
If the SAN OS keeps event logs you could try to correlate with the event; beyond that you may just have to do some testing.
As you say, someone somewhere had to do a repartition; the hard part is determining where the error is. Good luck.
