What I am about to say may seem silly, especially considering your email address, but try cleaning that tape drive, even if it was recently cleaned.
It is brand new. I did clean it, but that did not seem to affect the condition.

Do you get any SCSI error messages on your server?
Yes (note that mptscsih and mptbase are drivers for the SCSI card):

Oh, and double-check with software tech support that your S-AIT1 drive is using the latest firmware.
I will attempt to check the version tomorrow morning.
Using the sonytape utility fails to open the device.
I also suggest you try mounting a tape you can afford to overwrite and then blow out its label with tar. Then try relabeling that tape again via NetWorker and see what happens.
It's a brand new tape.

Hi, I'm a new poster to this list, but have used NetWorker for over 10 years
on Sun boxes.

I just moved our software from a Sun Solaris box to a Fedora Core 4 x86 box.
   Dell Pentium D Server
   ATTO ExpressPCI UL4D SCSI Card
   Sony SAIT-1 Stand Alone SCSI drive
   Networker 7.3

The install seems to be basically working. I can label and mount a tape and
start a backup.  It runs fine until the tape is full.

The problem is that after unmounting the first tape, I want to label and mount a second tape. When I bring up the label window (and confirm that the Device, Volume Label, Pools, etc. are all correct) and press OK, an error window pops up that says "write open error: drive status is" and then a
blank line.

Sometimes it's "read open error" instead, but that's all I can get out of it. I was only able to do anything with the drive by rebooting the PC, but again, after it was done with the one tape, it hung with the same problem.

Any pointers or suggestions would be appreciated.
