Judson, The IBM development team is investigating this problem. Under SLES11 the following loop will always hang at the "chccwdev -d":
while true; do
chccwdev -e 0.0.0152;
dasdfmt -y -b 4096 -f /dev/dasdc;
dd bs=4096 if=/dev/dasdb of=/dev/dasdc;
chccwdev -d 0.0.0152;
done
As a temporary workaround, ( although I believe that the "sleep" is not
needed in the clone.sh script ) the following loop will not hang (Note the
"sync" after the "dd":
while true; do
chccwdev -e 0.0.0152;
sleep 1
dasdfmt -y -b 4096 -f /dev/dasdc;
dd bs=4096 if=/dev/dasdb of=/dev/dasdc;
sync;
chccwdev -d 0.0.0152;
done

I ran into this while using the clone.sh from Mike's SLES10SP2 cookbook,
lightly modified. It does not appear to hang if I perform the cloning
steps,
from the book, manually. I searched the list and caught a thread about this
from July 09. Any update on why this is happening?
