Exabyte tape drive & SunOS 4.0.3

[Rich Jaenson]

I just upgrade the system from SunOS 3.5 to SunOS 4.0.3.  At the same
time, our department bought an Artecon 8mm tape drive.  Since the server
which is a 3/260 has no SCSI port, I connect the tape drive to one of its
clients which is a 3/50. So all dumps are remote. Here comes the odd
things. I can dump the files and there is no error reported.  But I can
only read some of the file systems. After trying a lot of experiments, I
find that one of the disk partitions gives me problem, I cannot read any
file system after that file system. I even tried to re-format the disk,
which is a SMD disk and the result is still the same. I have no idea of
what is going wrong.  Here is the error message appearing on the console
of that client when I try to read that file system:

st0:  failed cmd =  11  1  0  0  2  0  
st0 error:  sense key(0x9): vendor unique
	sense = 70  0  9  0  ff  ff  ff  12  0  0  0  0  0  0  0  0  0  0  0  0  40  0  0  1f  b7  e9  0  0  
st0:  failed cmd =  11  1  0  0  1  0  
st0 error:  sense key(0x9): vendor unique
	sense = 70  0  9  0  ff  ff  ff  12  0  0  0  0  0  0  0  0  0  0  0  0  40  0  0  1f  b8  c  0  0  
st0:  file positioning error

What does "vendor unique" mean?  Does anyone has a similar problem?
