When trying to do backups to my FreeBSD 2.1 system my 4mm 5gig Python
tape drive reports "st0(ahc0:4:0): Target Busy" numerous times and

positive affect.

 	Send a large dump to the tape drive.

 Hmm, here is the output from my ARCHIVE 4mm
 
 (aha0:6:0): "ARCHIVE Python 25588-XXX 2.96" type 1 removable SCSI 2
 st0(aha0:6:0): Sequential-Access density code 0x13, 512-byte blocks, write-enabled
 
 I've done quite a few dumps (and one restore even) with my tape drive on
 2.1-stable w/out any problems.

 It's possible that it's a drive problem but unlikely. We have two identical driv
 es
 and both act the same. However, on the our sparc 10s there are no problems.
