nbdecommission - "partial" decommissions, skipping OST disk

I am migrating ~ 300 to 400 media server in 14 NB domains from tape to Data Domain.  When I am done, I will be required to decommission "most" of the tape libraries (maybe 14 of 20) and tape drive...

    Hi,

     

    Understood. What you can do is use the 'nbdecommision -oldserver SERVERNAME -list_ref' command. It would show you where there are references to the media server in question so you can action the specific cleanup.

     

    It might help a bit.

     

    See output below.
