Hello,
Just in case anyone wants to follow my original problem in the future, I
resolved my no swap problem according to Nate's advice as follows:
1. Confirmed that /dev/VolGroup00/swap was not in use by the system
2. Ran the following commands:
mkswap /dev/VolGroup00/swap
swapon /dev/VolGroup00/

According to 'man swapon', swapon -s means:
Display swap usage summary by device. Equivalent to "cat
/proc/swaps". Not available before Linux 2.1.25.

I'm in a slightly unusual situation and I'd really appreciate some advice.
