Thanks to everyone who helped I basically followed the procedure below

Version 50

1)      In smit define the Logical volumes
2)      In ADSM format and create the appropriate db vols and log vols
        -define dbvol BLAH FORMATSIZE=SUPERBLAH
        -define logvol BLAH FORMATSIZE=SUPERBLAH
        -define vol WEIRD BLAH FORMATSIZE=SUPERBLAH
3)      Extend the logs and db by the amount
        -extend DB SUPERBLAH
        -extend LOG SUPERBLAH
4)      Reduce by the amount of the old vols (q dbvol, q logvol), for
        disk migrate the data off to Tape
        -reduce DB NOTBLAH
        -reduce LOG NOTBLAH
        -update stg WIERD HI=0 LO=0
5)      Delete the old volumes
        -delete dbvol OLDBLAH
        -delete logvol OLDBLAH
        -delete vol OLDBLAH

I didn't verify the procedure, but that should be about it.  Thanks for
all your help.
