That's correct - under Linux, IDE hard disks (/dev/hd*) can have up to
63 partitions but SCSI and RAID controllers like the CCISS are limited
to 15 partitions (16 if you count the whole-device) due to the way minor
numbers are allocated to /dev/sd* nodes.

You could cheat and map the additional partitions using kpartx - run
"kpartx -a /dev/cciss/c0d0" and this should create a device-mapper
device for each partition under /dev/mapper/c0d0p*. You can remove them
again with "kpartx -d /dev/cciss/c0d0".

That said, it might be better to reconsider your partitioning scheme and
see if you really need that number of partition table entries.
