SUMMARY: Archive Viper QIC-150 DU 3.2C
We knew that the QIC-150 has been used with OSF/1 2.1.So I reinstalled
OSF/1 2.1 and the tapedrive showed I/O error using tar or mt -f stat
command.Second drive showed the same problem.For my tests I used two
scratchtapes which had been erased with a strong magnetic field.
For verifying the two scratchtapes I wrote with tar files at a SPARC10
with SUNos 4.1.3 and it worked fine without any problems.
Now I moved the tapes to the ALPHA and everything worked fine.
solution: When you boot Digital Unix and you insert brandnew
or erased tapes (with magnetic field) into a QIC-150
tapedrive, you will get I/O error.
Insert a good tape with files on it and do the following
command "mt -f /dev/nrmt0m stat".
Now your new tapes will work fine.
2. Problem: When you write to a QIC-150 tapedrive with the wrong
density "tar cvf /dev/nrmt0a . " you will get I/O error
and your drive will not write when you then give the
correct density "tar cvf /dev/nrmt0m . "
Powering the tapedrive down and up helps.
Thanks to Dr. Thomas P. Blinn from the DEC UNIX Software Group for
his fast response.
