Title: One ACS robot, two NBU masters

Yes, it works without a problem.  I have 2 masters, one is 4.5 and the other is 5.1.  We are using STK 9310 with the first master and added the second master when 5.1 came out.  We designed a tape range of 100000 – 199999 to the 4.5 master and 500000 – 599999 to the 5.1 master.  In order to stop one master from inventorying the tape range of the other master, we are using INVENTORY_FILTER.  To use this, you need to put your tape range into a pool within your library.  Since we started with 1 master and added the second, we did not define pools for the tapes in ACS, therefore all 100000 range tape took the default pool of 1.  When the second master was added, after the tapes are loaded into the library (the 500000 range), I ran this command in ACS to put the 500000 range tapes into a pool called 50.  set scratch 50 500000-500999.  You will have to do this every time you add new tapes.   In NetBackup, you need to add the following line to vm.conf:   INVENTORY_FILTER = ACS 1 BY_ACS_POOL 50   I have ACS 1 and the using pool 50 for the second master.  You need to add this to both masters but change the pool number.  Recycle your NetBackup and do an inventory check and you should be good to go.   One other thing.  A bug.  If you are running NetBackup Administrator Console on your Windows desktop and you do an inventory, the output will show ALL of the tapes.  The reason is because the NetBackup Administrator Console does not have the vm.conf on your desktop and therefore, does not know that you are filtering.  You need to run either jnbSA from the master server or run the Java Console instead.   Cheers, Ken   -----Original Message----- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] On Behalf Of Geyer, Gregory Sent: Monday, November 21, 2005 2:02 PM To: veritas-bu@mailman.eng.auburn.edu Subject: [Veritas-bu] One ACS robot, two NBU masters   We have one large STK library and want to have two master NBU servers (one 5.x for now, the other 6.0) access it.  The environments will NOT share drives or tapes, and we hear there should be no issue sharing the robotics (its shared now with 30+ SAN media servers), but wanted to hear if anyone has a similar environment without any issues. A concern would be having an inventory mix the tapes in the environment.  I see the "Robotic Inventory Filtering" in the ACS appendix of the MM Sys Admin guide but no experience using it. So does anyone out there use two masters with one ACS robot? G.
