Ah ha!

The mkswap I was using had the L option, but it was not listed as an 
option.  I ran the '/sbin/mkswap -c -v1 -L SWAP-i2o/hdb3 /dev/i2o/hdb3', 
and it worked.  I then swapon, and swap is now added.

I then yum'd util-linux, and did another man mkswap, and this time the L 
option is listed.

Thanks!
