The first half of what Roberto was saying was precisely correct. I didn't pick up on the trailing 'p'.
The actual container (logical disk) is the device node:
/dev/cciss/c0d0
So you want to use:
fdisk -l /dev/cciss/c0d0
The 'p[0-9]' is the partition number of the disk 'd0' on controller 0 ('c0').
It does all make sense ;) A simple 'ls -l /dev/cciss | more' will show all of the previously created device nodes. Browsing through them should make sense now.
