We have a similar, but different solution.  We have a script we use to
rename AIX tape devices to a predictable name, based on the last 4
characters of the WWN.  After running it on each AIX system, the device
names will be the same on each system.  After running "tsmchrmt rmt0", the
device will have a name similar to:
rmt.f0c6.0.0
where "f0c6" are the last 4 chars of the device's WWN.

I don't recall where we got the seed for this script, but here is our
version, which we call "tsmchrmt":

----
#!/bin/sh
if [ $# != 1 ]
then
   echo "must specify 1 rmt device name as an argument."
   exit 4
fi
d=$1

WWN=`/usr/sbin/lsattr -El $d -a ww_name|cut -f2 -d" "|cut -c15-`
LUN=`/usr/sbin/lsattr -El $d -a lun_id|cut -f2 -d" "|cut -c3`
root=`echo $d|cut -c1-3`
new_name=$root.$WWN.$LUN.0
let "j=0"
while [[ -e /dev/$new_name ]]
do
         let "j=j+1"
         new_name=$root.$WWN.$LUN.$j
done
/usr/sbin/chdev -l $d -a new_name=$new_name
