Hello,

We are working on getting NDMP to work on our production backup server.  the backup server (both test and production) runs CA BrightStor v12.5 with dynamic device sharing on.

Our test server successfully does ndmp backups (this would mean the nas is configured correctly - would you agree?). 

our production server does not backup by ndmp successfully.

the test server does not have any fiber switch zoning to it.  our production server has zoning to a clariion for storage.  it also has a zone in the fiber switch from the production server to the tapes in the tape library unit.

We get the scsi reservation error message when looking at the nas logs. 

i am looking for feedback if the zoning to the tlu is needed? or any other thoughts.

(due to backups running, we can only test this when the backup environment is idle every few weeks)

Thanks in advance.
