Interesting. The juke is full, all 5 tape slots are occupied. chio does work if I run it directly. I can change tapes, etc. I only seem to run into problems when I do anything through the am* files.Never used chio so I looked at the source and found this comment:# The changer being used is a n tape juke, that can be used with 1, n-1 or n # tapes in the juke. The special slot is slot n. The script does not # make assumptions about the number of slots, except that the special slot # is the highest number. The slot is special in the sense that it contains the # the only tape if the juke contains 1 tape and contains no tape if the juke # contains n-1 tapes. Is there any chance you don't have the required number of tapes in the juke, completely full full minus one with last slot empty 1 tape only, and in the last, not first slot? According to the comment those are the only valid configs.
Just the tape device itself, nsa0. Perms for that seem fine and I haven't changed them:> At 01:01 AM 11/17/2002 -0500, Jon LaBadie wrote: > > >If so, to rule out device permissions further, does amlabel work when > >either of the following is true: > > > >1. /dev/ch0 is set to permissions 666. > >2. amlabel is group operator and setgid (permissions 2755). > > I ran amlabel before and after both 1 and 2 above.

Do you have a separate device for read/write? Permission probs there?

Heh, unfortunately the Permission denied error comes up right after I tap the enter key. It doesn't even have time to check the tape hardware. Write protect tabs are correctly set though.Is the write protect tab on the tape correctly set :)
I'm not sure if it's important or not but as "amanda" user I can use chio to operate the robot to change tapes etc. Which seems like /dev/ch0 is being read. I don't think that moving tapes around touches /dev/nsa0 since that's the tape itself.
All this above is using chg-scsi which is what I'd like to do. If I use chg-multi however, which doesn't use chio nor /dev/ch0, I *can* write labels with amlabel. It sounds like /dev/nsa0 is OK since I can write to the tape and chio is OK since I can use it directly, but something with ch0 is not so OK. Either that or maybe something with amanda (the software) when it's using the chg-scsi stuff.
