This errror is created by Ignite replication of an hpvm system. The following checks device integrity and cleans up errors created by Ignite replication.
hpvmcreate: ERROR (jdeautp1): Incorrect backing device type.
First check for errors with this script (I may check this in at some point)
#!/usr/bin/sh
#
# Unofficial quick and dirty passthru DSF check script
#
# It walks all /dev/pt/* files and tries to find corresponding /dev/rdisk
# or /dev/rtape files. If they are foudn their minor numbers are compared.
#
# @(#) pt_check.sh v1.1 – stanm@wtec
#
for i in $(ls /dev/pt/*)
do
# ll $i
shortname=${i##*_}
printf “checking $shortname”
minor1=$(ll $i|awk ‘{print $6}’)
# echo minor1=$minor ($i)
if [ -c /dev/rdisk/$shortname ]; then
minor2=$(ll /dev/rdisk/$shortname|awk ‘{print $6}’)
# echo minor2=$minor2 ($/dev/rdisk/$shortname)
if [[ "x$minor1" = "x$minor2" ]]; then
printf ” – OK\n”
else
printf ” – Minor numbers are probably incorrect\n”
printf “minor1=$minor1 ($i) vs ”

Correction procedure:
cd /var/opt/hpvm/common/
rm -f hpvm_devinit
cd /dev/pt
ls
rm -f *

Consider this a necessary procedure to clean up after ignite replication
