I think I got things working.
Just for future reference here it is in a nutshell:
First define this in the config for "vtapes"
tapecycle 30 tapes
autolabel "vtapes-%%%"
labelstr "^vtapes-[0-9][0-9]*$"
tpchanger "chg-disk:/vtapes-1"
Create the slots and the labels for the 1st part of the mirror:
~># for i in `seq 1 30`; do su amanda -c "mkdir /vtapes-1/slot$i"; done
~># for i in `seq 1 30`; do su amanda -c "~amanda/sbin/amlabel vtapes slot $i";
done
Reading label...
Found an empty tape.
Writing label 'vtapes-001'...
Checking label...
...
Reading label...
Found an empty tape.
Writing label 'vtapes-030'...
Checking label...
Success!
Then modify the tpchanger to point to the second part of the mirror
(ie s/vtapes-1/vtapes-2):
tpchanger "chg-disk:/vtapes-2"
Force (-f) the labeling of the tapes in the 2nd changer with:
~># for i in `seq 1 30`; do su amanda -c "mkdir /vtapes-2/slot$i"; done
~># for i in `seq 1 30`; do su amanda -c "~amanda/sbin/amlabel -f vtapes slot
$i"; done
Reading label...
Found an empty tape.
Writing label 'vtapes-001'...
...
Reading label...
Found an empty tape.
Writing label 'vtapes-030'...
Checking label...
Success!
Change the tpchanger definition to use the chg-rait:
tpchanger "chg-rait:{chg-disk:/vtapes-1,chg-disk:/vtapes-2}"
amanda is now happy:
~># # su amanda -c "~amanda/sbin/amcheck vtapes"
Amanda Tape Server Host Check
-----------------------------
slot {5,5}: volume 'vtapes-5'
Will write to volume 'vtapes-5' in slot {5,5}.
NOTE: skipping tape-writable test
Server check took 1.037 seconds
Amanda Backup Client Hosts Check
--------------------------------
Client check: 1 host checked in 0.129 seconds. 0 problems found.

One final note: I don't think the labeling script located at
http://wiki.zmanda.com/index.php/File:Createvtapes.sh.txt
and referenced at:
http://wiki.zmanda.com/index.php/How_To:Set_Up_Virtual_Tapes
is very useful as it stands. It should either be fixed or removed.
