We implemented a switchover from Veritas to NW and now we are looking to move 
off NW after 2 months. We found yet another bug that causes data loss. We are 
running 7.3.2 Jumbo 11.


Below is the stdout from the nsrclone command on one ssid, run from the command 
line. As you can see it encountered an error but then verbally says that the 
clone finished successfully and the return code is zero indicating success. We 
tried to restore from this clone and it was missing 9GB's of 16GB's. We have 
opened a case with EMC and submitted a bug report but after looking through the 
daemon logs there are other instances of this happening. We were using scripts 
to automate the cloning. The script checked the return code of each clone to 
verify and ran an mminfo to check flags too but there is a major bug in the 
nsrclone command.
