Todd,
        You will be OK with 3 drives on each fabric and the server
seeing the robotics, this is a common setup. 
        The flow goes something along the lines of (A = server B =
storage Node)
A - require a tape mounted on storage node
A - check devices on storage node
A - Jukebox? - who controls it?
A - send a mount to the controller of the jukebox
A - ask B to verify tape label
B - verifies tape
A - receive confirmation of load
B - uses tape

Regards
Bob

Hi all,

I'll be upgrading our backup infrastructure and need a sanity check. I
have an ADIC Scalar i2000 that I want to share between an AIX server and
a Windows 2003 storage node. The library will have 2 I/O blades, each of
which has 2 connections to SAN fabrics. We have separate redundant
fabrics for Windows and UNIX servers and my plan is to connect 1 I/O
blade to the Windows fabrics and the other I/O blade to the UNIX
fabrics. Each I/O blade would have 3 LTO-2 drives attached to it. I
would like for the server to control the robot and own 3 drives and for
the storage node to own the other 3 drives. This is where I become
confused...

If 3 of the drives are on different fabrics than the server, would it be
able to mount/unmount tapes for those drives? Connected this way, the
server should only see 3 of the drives (and the robot), so there
wouldn't be any OS devices created for the other 3 drives, but would
jbconfig still discover all 6 drives when it queries the library and I
could just select which box owns each drive?

Also, on page 440 of the UNIX admin guide, it states that "Autochanger
sharing is automatically enabled as part of Power Edition and Network
Edition". Yet, on page 441, it states that "Only Network Edition
requires you to license autochanger sharing".

Does anyone know if it actually is enabled in the Network Edition of
7.1?

I look forward to your responses... Thanks!
