I've been attempting to update my dom0 kernel by using the 2.6.27 git
tree from the xenclient repo and also to 2.6.30 using opensuse patches
rebased by Andrew Lyon. In both cases there's a problem with the 3ware
3w_9xxx driver incorrectly detecting the LUNs on the device or some
other issue, which ultimately prevents partition table detection.
In my testing I applied the latest and greatest 3w_9xxx driver from
3ware's site to both 2.6.30 _and_ 2.6.18. The same driver works
correctly under 2.6.18 but fails under 2.6.[27,29,30]. The results were
same as with the kernel-provided versions.
"only 511 (max_scsi_report_luns) of 788538 luns reported" <-- I don't
think so.
Xen 3.3.2 64bit, PAE dom0.
Here's an excerpt from 2.6.30 (failing):

Any clues?
