615.0. "Segmenting and sharing a TL8xx Jukebox" by NNTPD::"[email protected]" (Heinz Kenntner) Wed Apr 23 1997 08:05

I have never had the chance to play with such a device so I need to ask this
crowd. I understand that such a device has at least two drives and one (or
more)
interfaces to the robot.
One of our customers has the idea of segmenting and sharing a TL8xx jukebox
between two or three systems running NetWorker. I understand (I might be wrong
though ...) that you could physically hook up the jukebox to the various
systems by attaching SCSI cables to each drive of the TL and the systems.
But then I am still unsure if NetWorker could deal with such a segmented
jukebox.

Any idea if this is doable ? Any gotchas ?

Thnx and cheers

615.1DECWET::LENOXa bit too excitingWed Apr 23 1997 09:157
It is not a supported configuration.  NetWorker assumes
it owns the jukebox, and for now it also assumes it is on
only one system (no way to operate robotics from remote
systems, there is only one interface to the robot).  Are
they thinking that clients can use a tape drive directly
or do they really need 2 or 3 NetWorker servers?  
615.2Direct access requestedNNTPD::"[email protected]"Heinz KenntnerThu Apr 24 1997 02:0414
They do want to use the different drives in the jukebox from each system as
they
where local drives. They want to r/w directly to the drives. They do not
want to go over the network (what they could when having one NSR server
owning the jukebox and they other systems being NSR clients) because they
feel they do not have they neccessary network bandwidth nor want they to
invest in improving their network bandwidth.
The other reason they want to do this is to minimize the effect of a NSR
server breakdown. Having - let's say three server sharing the jukebox and
one breaks down, then the others still could do backups using the jukebox.

615.3not supportedDECWET::CARRUTHERSLife gets easier when you realize you can't have everything.Thu Apr 24 1997 10:282
The configuration of the jukebox as detailed in .2 is not supported
by NetWorker.
