quantum lto 4 hh and linux
 
Has anyone experience of using Quantum lto 4 hh on linux? The Quantum site says it is not compatible with RHEL5 but I have downloaded a module mt-st and this seems to communicate well with the tape drive ... does this mean that the not-compatible only extends to native RHEL-5 not with the added module mt-st which adds compatibility with scsi tape drives?

If quantum will work directly on RHEL 5 then one can get Amanda up and running otherwise those lovely people at proprietary backup vendors will offer me compatibility at say 5k for commVault etc or 1k for Symantec. Such kind and helpful people. Also they require I find a windows server to install the base modules. So helpful.

If you can get mt to work with the tape drive, then Amanda will work with it. Find the right device, perhaps st0. Then if you can do things like `mt -f /dev/nst0 status`, etc., you should be ok.

Get an Amanda distribution or source and install it. Then use `amtapetype -f /dev/nst0` to run it through its paces and check the performance. That will take quite a while, because it writes the whole tape once or twice, but it makes sure it works and determines the tape size and performance on your system. You need to make sure you have compression turned off on the tape drive and a new tape.

One issue with the faster drives of recent years is that you really have to have your computer properly configured and tuned to keep up with the tape drive. If you have a desktop machine with a shared bus for drives and other cost cutting designs, you may have issues with pulling data fast enough to push the drive. A server will be designed and configured to be able to maintain the data transfer speeds.

thanks Choogendyk, I am away for several days in Barcelona :-) but will check out your suggestions as soon as I return. I did mt status and erase and they both worked well. I will next install Amanda and follow your test.

I'm trying to get this drive mounted as well on a similar rhel 5 instance. Would you mind sharing what was the mt-st module you downloaded to get it to work?
