After some playing around, I've solved my own problem. If anyone is having the same issues, the key issue seems to be that the mptbase module is not being loaded. On the head node, run:
mkinitrd -v -f --preload mptbase --preload mptsas --preload ata_piix --force-scsi-probe --without-dmraid --fstab=/var/lib/systemimager/images/oscarimage/etc/fstab.fake /var/lib/systemimager/images/oscarimage/boot/initrd-2.6.18-164.el5 2.6.18-164.el5 where you must of course use your own image name and kernel version in the appropriate places. Make sure your fstab.fake file is correct (mine required some editing). This fix is likely hardware specific to Dell PowerEdges with SAS.
