Hi, Jane,

   It's the same stuff. zmi gives same errors than deleting on zendmd

   thanks for the fast response, anyway

At last, I would like to add...

   in this case, (I assume) the catalog got so weird that zendevicedump got killed for having consumed all memory system.

   I didn't want to loose those devices so i wrote a little dmd script for generating a zenbatchload file, i post it here in case anyone needs it. It respects heritance of zproperties and tries to get the most resumed. It's a kind script done for generating the batch load file and then REVISING before zenbatchload it.

   Here it goes:

   And here goes the paste (i'm a newbie with python, so i'm anticipatedly sorry for my sins on this script):

          c=' %s=%s,'%(zProperty[0],zProperty[1])
