[Mtx-general] mtx/spectralogic treefrog/adaptec problems

[Alex F. <A....@la...>]

 Hi,
 
 I am having infuriating problems with the following setup

 Linux
 mtx
 adaptec 29160 scsi card
 spectralogic treefrog

 When I first bought it it worked fine for about a year. Then it randomly started getting errors. After returning it
to the vendor, and getting a replacement and buying a second card and putting it on a different machine and trying different
cables and terminators...

  I could get no consistent answer as to the cause. Then one day it started working again.

 Two weeks ago it stopped again.

 The symptoms are that I can access the tape drive ok with mt, but mtx refuses to talk to the robot, it says:

 Can anyone help, as without the robot the weekly backup is going to require me to hand load the tapes.
