Does rmt/0 also work (say with tar or dd)? > changer /dev/sq/c3t610 (created using Veritas stuff, I can't vouch for it) Guessing here, "sq == sequential", which is one of the sgen driver types. An c3tXXX sounds like "c == controller 3", "t == target XXX", but certainly not target 610 as the target generally means scsi id, like 0-15. Are you sure that is not c3t6d0 (target 6 device, i.e. lun, 0). But the location is not what I've seen. What is /dev/sq/c3t610, a device, a symlink (to what?)? Is there a /dev/scsi/sequential/* with maybe the same information?

Not surprising that mtx didn't create a device. It doesn't. It operates on a changer device. Maybe your /dev/sq/* device. > >Thought 5. /dev/rmt/1n ?

Do you only have one tape drive/changer? Is other software going to be screwed up in some important way if the device names change? If only 1 and no other software problems, you could get a complete device reconfiguation and likely move the drive to drive 0, removing all else. The stuff in /dev/rmt are just symlinks to stuff in /devices. A device reconfiguration at reboot would entail "touch /reconfigure" and reboot or at boot time, at the ok prompt, do a "b -r" (boot -r). Sometimes old stuff keeps reappearing. If so, rm all the /devices/.../*st* (st == scsi tape, or is it sequential tape) devices that are pointed to from /dev/rmt and all the /dev/rmt links. Then either the reconfiguration reboot or read up on devfsadm to recreate the devices without reboot. The deprecated, obscelescent command "tapes" would also do the same device recreation I think. > >Thought 6. the device /dev/rmt/1n is choosing the "default" density and/or > compression for your tape drive. > If that is what you want, fine, otherwise check into 1ln, 1mn, ... > > Ah, wondered what they all were! > I'll investigate, thanks for the "heads up" prtconf -v will give lots of output including some stuff about "st" devices. Included will be what tape device(s) it recognizes at boot time. From this you can get pointers into the /kernel/drv/st.conf file to explore further the entries for that kind of tape drive. -- Jon H.

Thought 1, its good to specify which amanda version you are using. Thought 2. you did not say if you had a changer, make, model, /dev entry. if not, you needn't use any changer entries Thought 3. you have changerfile set to chg-multi. that would suggest your tpchanger should also be chg-multi Thought 4. for my Solaris system and drive chg-mtx worked fine. others have used chg-zd-mtx (note you will have to obtain and install mtx). still others have configured the "sgen" (generic scsi?) driver and used chg-scsi, or the chg-mtx's Thought 5. /dev/rmt/1n ? Do you have another tape drive at 0? Thought 6. the device /dev/rmt/1n is choosing the "default" density and/or compression for your tape drive. if that is what you want, fine, otherwise check into 1ln, 1mn, ... -- Jon H.

Help getting tape changer to work on Solaris 2.8
Hi I'm trying to set up amanda, struggling a bit. (My fault, I suspect, nothing to do with the software!) Here's the current error :- $amtape Daily reset amtape: no tpchanger specified in "/usr/local/etc/amanda/Daily/amanda.conf" $ Here is the relevant section of the amanda.conf file :- #runtapes 1# number of tapes to be used in a single run of amdump #tpchanger "chg-manual"# the tape-changer glue script tapedev "/dev/rmt/1n"# the no-rewind tape device to be used #rawtapedev "/dev/null"# the raw device to be used (ftape only) changerfile "/usr/local/share/amanda/Daily/chg-multi.conf" #changerfile "/usr/adm/amanda/DailySet1/changer-status" #changerfile "/usr/local/etc/amanda/DailySet1/changer.conf" #changerdev "/dev/null" Assuming that I need to uncomment the tpchanger line, what should I point it at? Am I right customising and using chg-multi.conf? Any thoughts/guidance appreciated.
