You may have to do an odmget/odmdelete if you can't sync up those LV's. Then start over.

odmget -q name=$1 CuDv >> $FILE1
odmget -q name=$1 CuAt >> $FILE1
odmget -q name=$1 CuVPD >> $FILE1
odmget -q value3=$1 CuDvDr >> $FILE1

        # Delete existing ODM definitions
odmdelete -q name=$1 -o CuDv > /dev/null 2>&1
odmdelete -q name=$1 -o CuAt > /dev/null 2>&1
odmdelete -q name=$1 -o CuVPD > /dev/null 2>&1
odmdelete -q value3=$1 -o CuDvDr > /dev/null 2>&1

I guess it's all over by now - one way or another. Still, some thoughts for
next time...
In theory, you can't lose any data, because there's always a valid copy of
the partition.
I would be wary of a Ctrl-C, though. My main concern would be that it might
leave child processes running. Before you attempt it, open up another
session and trace the process tree so that you can be sure it's all gone at
the end.
