I've not looked at the code, but if chg-scsi detects it via the
status request it might show up in the "mtx status" output.  If so,
then it would be 'easy' :) to add that capability to chg-zd-mtx.

Amanda does support a form of it own RAIT.  But I don't think it
is well tested as few people report trying or using it.

dumpcycle 7
tapecycle "something greater than 14"
runspercycle 5 or 6 or 7

Amdump can be run anytime by hand specifying the hosts and DLEs.
You can also force, with amadmin, a level 0 of any DLEs for the
next amdump run.

A separate config could be setup sharing many of the control files
(disklist, indexes, curinfo, tapelist, changer.conf, ...) but with
record set to no and a dumpcycle of 0 (always level 0).  Then you
could run amdump for that config and leave the standard one alone.
Be careful they don't try to run at the same time.

Well, I have chg-zd-mtx working. In the process, I remembered 
why I had chosen chg-scsi originally. The main reason is that it 
detectes when a drive is requesting to be cleaned and will 
initiate a clean cycle when needed rather than by access count.

It is too bad that neither ch-zd-mtx nore chg-scsi support RAIT 
as that is the way I would like to eventially go.

My desire is to set up automated backups that back up everything 
that was changed on a daily basis and does a complete backup of 
the production file systems at least once a week. I also want to 
be able to do system file systems (/etc, /, /usr, etc.) on 
demand.

Again, any configuration suggestions will be greatly 
appreciated.

No reason at all other than there is nothing in the 
documentation that would indicate that it is a better choice. 
The docs seem to indicate that the chg-scsi is a more direct 
interface, especially for the Linux 2.6 kernel that has changer 
support.

I am still baffled that my earlier request for configuration 
suggestions only got one reply and that was to say "read the 
wiki" which provided no more insight than the other docs. Is no 
one out there using an adic Scalar tape library? It seems odd 
that if no one is using it that chg-scsi recognizes it 
specifically.

I'll give chg-zd-mtx a try.

I decided to try to label a tape. After that failed miserably, I 
decided to take a step back and just try to get chg-scsi to 
work.


Is there a reason you cannot use chg-zd-mtx?  If your changer works with 
mtx, that might be simpler to set up.
