Hi,
First of all, I'd like to apologise for the cross post, but this has been knacking me off for 2 weeks now, and I really want to get this sorted... :)
Having some minor issues with Amanda on OpenBSD3.4, talking to a Dell Powervault 120T 7-slot changer/drive. After eventually working my way through the changer scripts I've found that chg-chio is the one for me. chg-scsi, couldn't figure out the configuration files and couldn't take to the jukebox, but chg-chio, using the chio program works fine.
The issue that I have now is that I'm finding amtape unreliable at moving tapes around effectively, and also that it's having problems rewinding tapes. I don't know if this is an OpenBSD related issue or an Amanda issue. I'm using the latest release version that I could find on the site (amanda-2.4.4p3) compiled from source.
Using chio to move tapes between slots works perfectly, so I don't think it's a changer issue, and I can't find any mention of the error messages in the changer code. It looks like it's having some issues with regards to rewinding the tapes, and not handling the time that the tape would take to rewind. In my configuration, it seems that the taper has no method of handling the fact that the drive is not ready, and just returns a file handle open error on /dev/nrst0. I suppose that I would either need to know how to get the Dell Powervault 120T working under the chg-scsi driver, or some means of adding a delay into the process to allow the drive to ready itself before letting ammt get anywhere near /dev/nrst0.
My configuration is called ltsn. Here is an example of what happens when changing a tape around:
bash-2.05b# /usr/local/sbin/amtape ltsn slot first
amtape: could not rewind /dev/nrst0: tape_rewind: tape open: /dev/nrst0: Input/output erroramtape: changed to slot 1 on /dev/nrst0

Whilst the drive is not ready, this message appears in the dmesg:
