Try replacing "LABEL=SWAP-cciss/c0d0p" with /dev/cciss/c0d0p? where
the question mark should be replaced with the partition number of
your swap partition. You might use fdisk to find the right partition:
fdisk -l /dev/cciss/c0d0

The answer is right in front of your eyes. The rest of the memory
is used for cache and buffers. You should compare the number 2891992
with 2659344, not a big difference.
