I'm also nat familiar with "unmasking" but one of the things I found
clears up a lot of these issues is to remove/recreate all the EMC
devices and re-import the volume group. Here is a little script we've
used for years.
Good Luck - Steve

# rm powerdisk device files

lsdev -Cc disk|grep hdiskpower|awk '{print $1}'|while read hdiskpower

if [ $? -ne 0 ]
then
echo "rmdev -dl $hdiskpower failed"
exit 1
fi
done

rmdev -dl $emcdisk
if [ $? -ne 0 ]
then
echo "rmdev -dl $emcdisk failed"
exit 1

exit 0
