Gregory-
Yes, I believe you could support both of your master servers (but they
would both have to be 6.0!) with a single EMM server.
This is roughly equivalent to Jim Peppas's response to your question,
suggesting that your two masters could share a single volume database
host. This is doable in some circumstances but NOT yours, because of
the fact that one of your masters is 6.0. (plus most of the Symantitas
support folks get the shakes when they hear about that kind of shared
volume database server configuration :-/)
I would second Kenneth's idea below; it is a very well-traveled path,
lots of people use the INVENTORY_FILTER stuff to share their ACS robots
among multiple master servers (and/or among multiple backup
applications...)

Here's another issue that recent 6.0 developments might make possible.
In 6.0 there's the EMM database which controls resources like device
info, active drive status, the volume database among many other things.
In the in-depth 6.0 diffs web-class yesterday it was stated that the
EMM
database can support multiple masters. So it would seem possible that
with one EMM database we could have multiple masters also sharing tape
drives, since they'd already be sharing robotics anyway. Anybody read
this different?

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

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?
