Probably others can give better details I'm afraid of this 8-(. The cable capabilities are up 8 devices and there is a little chaos inside the box. I'm going to check then.. bye.,Sanya

Odds are pretty good that you have a SCSI cabling problem. Either 16-bit -> 8-bit not terminated properly, or maybe just the length of cable.

I think there are problems about device itself but any further suggestions would be appreciated. thanks, Sanya

I see similar problems with 'amtape current' or 'amlabel' quite often, but if I run the same command again (sometimes I need to do it twice) it eventually comes back correctly. I'm not sure what causes it, but I'd guess there's some time-out somewhere that needs to be increased. It almost seems that amanda isn't waiting long enough for the tape drive to get back to her. -- Seeya, Paul ...we don't need to be perfect to be the best around, and we never stop trying to be better.
