RE: Use multiple drives in tape robot
Thanks for all the responses, pretty much confirming what I thought. I haven't done anything special with the ports yet though, both configs seem to run together just fine, but I haven't got multiple clients involved in this config, I'm just testing out the concepts. I need to look at port ranges etc. next as if we start using Amanda more widely then firewalls will definitely be involved and will need to be locked down as far as possible. regards, Phil -Original Message- I'll just add that you must also configure amanda such that both configs use different ports with '--with-testing=config1' and '--with-testing=config2' and add those to /etc/services like amanda-config110080/tcp amanda-config110080/udp amanda-config210081/tcp amanda-config210081/udp Depending on the authentication scheme you decide to use you might have to specify the udp and tcp port range so that both config don't overlap.

Re: Use multiple drives in tape robot
--with-testing was needed with amanda 2.4.* if a client could be accessed by 2 different config at the same time. --with-testing is not needed with amanda-2.5.*, the amandad deamon allow multiple request simultaneously.

This was successful, except one of the amdumps failed on the first calling saying no writable tape could be found; it worked on the 2nd calling so I suspect there is a clash with 2 configs trying to access the changer. I do exactly this, and have never seen a collision. I kick off the 2 amdumps 5 minutes apart.

The answer to your question is yes, but you must ensure that only one instance of mtx is running at a time. If your configurations each use one tape only, then it should be safe to start them at different times, as Joshua has suggested. If you have runtapes 1 for both configurations (and maybe even if not), you might consider wrapping MTX in a short script to ensure that only one copy runs at a time. --Ian I have successfully set up 1 config with chg-zd-mtx then tried duplicating that to a 2nd config using chg-zd-mtx with a different set of tapes in the robot, and the other drive.

Or am I barking up the wrong tree, is there a better way to do this (one of the other changer scripts?) or is it just not possible/supported? Thanks for any info or suggestions as to where in the documentation I should be looking.
