This is the original question:
Dear Managers,
I have an IBM 7208-001 SCSI 8mm 5GB tape unit and I want to connect it to
a DEC Alpha OSF/1 3.2 could it be possible?
Few months ago I added a Micropolis Hard Disk to the same machine,
I configured the /etc/disktab, but now I have no idea what file
do I need to configure to make the tape unit work. Some ideas are
welcome. Thanks in advance. I'll summarize.
Regards,
Rosy
This is the summary to install whatever tape drive:
1. As root:
#shutdown -h now
2. At console prompt, type
>>> sh dev
Take note that all disk and tape drives are currently seen.
3. Power off system.
4. Install tape drive with an unused SCSI ID number ( in my case 2).
5. Power up and login.
6. At console prompt, type the following:
>>> sh dev
Take note of new device.
7. Boot system and login.
8. Edit the host configuration file (sys/conf/MACHINENAME) and add the
entry for the new device after the entry for the related controller,
as in the following example:
bus tcds0 at tc0 slot 4 vector tcdsintr
controller scsi0 at tcds0 slot 0
device tape tz2 at scsi0 drive 16 <-line added
As Dale Cook told me tz2 denotes the device mnemonic/device number to
the scsi controller number. This number is calculated as:
(scsi_bus_num*8)+(scsi_device_num). So, since I have scsi 0, device 2,
the number is (0*8)+2=2=tz2. The last column is calculated as the
number derived above times 8, So in my case it's 2*8=16.
9. doconfig -c MACHINENAME
10. cp /vmunix /vmunix.save
11. mv /sys/MACHINENAME/vmunix /vmunix
12. shutdown -r now
13. cd /dev
#./MAKEDEV rz2 <--- SCSI ID number
And that's it. For the unit drive that I was trying to
install it does't work maybe for an firmware incompatibility
problem between the unit (IBM hardware) and the DEC machine.
Later I installed with the same configuration an hp unit and it
worked perfectly, I'll try again with the IBM unit, if I can make
it work I'll tell you.
Thanks again for all who responded.
Regards,
Rosy
