[comp.unix.sysv386] ISC 2.2 Floppy tape driver with CMS JUMBO

cboyes@ibmpcug.co.uk (Chris Boyes) (03/24/91)

I have been trying to install a CMS JUMBO floppy tape system
on a system running ISC UNIX 2.2, without success!
The method of installation was as per OS Guide section 7.16
1. Remove floppy disk driver
2. Add New floppy driver
3. Add Floppy tape driver
4. Rebuild and reinstall kernel

Normal UNIX floppy disk mounting and access was possible
but use of the ftape command as below gives errors as below:
 #ftape -t /dev/ftape
  /dev/ftape : no such device (after timeout)
then
 #ftape -t /dev/ftape
  /dev/ftape : device busy

Following this any attempt to access the floppy disk results
in a device busy message.

Just by chance I tried using the floppy disk via VP/ix as drive
A: (after rebooting and confirming floppy access via UNIX) and
no floppy tape access.

The result was a quick flash on the disk activity light and the 
VP/ix procces hung and could not be killed, in fact when used
from the console the only solution was to remove the power.
The tape drive functions perfectly using DOS and is not faulty.
The UK OEM supplier had no experience of the floppy tape driver
and was sympathetic but could not help. I would be greatfull if
anyone who may have used the floppy tape driver could give me
some help.

It may of course be a bug in the operator not the system !
I appologise if this problem has been seen on the net before I
am a new reader of news and this is my first posting.

I had the same problem. I finally called CMS Technical Support. They asked
me to check the rev level of my tape drive. Apparently there is a known
problem with a particular rev level. I fixed the bug by purchasing CMS's
new unix driver.

I suggest you call their tech support number (number in back of documenta-
tion and talk to them.
