rebuild tape device link in HP-UX 9

[Roberto Martinez_2]

ok, this one is just for those who were born before epoch...
We have an old HP-UX 9.05 system, which has /dev/rmt/0 linked to a disk. We want to rebuild the link so it points to the tape drive. What should we do? Thank you very much in advance.

Hi,

some time ago, but ...

first look, if a/the tape device is found:
ioscan -n

cd /dev/rmt
- look for the new tape devices (compare with ioscan-output):
ls -l
- remove the wrong links
- create new links
- don't forget, that you have rewinding and non-rewinding devices.

I worked on HP-UX 9.05, but I don't remember too much.

I think that if you just remove the existing device file /dev/rmt/0m with "rmsf" or however you do that on 9.05; and then ioscan -f, insf -e, he will just automatically rebuild you a new device file.

Hi,
This is what it should look like ...
in /dev:
dr-xr-xr-x 2 bin bin 1024 Feb 24 1995 rmt
in rmt:
crw-rw-rw- 1 bin bin 121 0x201306 Nov 17 1994 0m
crw-rw-rw- 1 bin bin 121 0x201307 Nov 17 1994 0mn
crw-rw-rw- 1 bin bin 121 0x20130e Nov 17 1994 3hc
crw-rw-rw- 1 bin bin 121 0x20130f Nov 17 1994 3hcn
crw-rw-rw- 1 bin bin 121 0x201306 Nov 17 1994 3m
crw-rw-rw- 1 bin bin 121 0x201307 Nov 17 1994 3mn


Good luck

HPUX9.05 was for serie 700 workstation if I remember...
Im looking for the Interface/Device Drivers and can only find in /etc/master:
scsitape stape 1 1FB -1 121
s2tape s2tape 1 FB -1 54
I know that these will cause sctl c700 to be in the kernel:
* Driver name .....
*
dskless lan01
scsi sctl
scsitape sctl s2tape
s2tape sctl scsitape
scsifloppy sctl

I dont remember if you create the sf with insf or mknod sorry, but I would connect the tape, reboot so HPUX detects the new tape drive and associate it with a device driver and try to use insf. Unfortunately I have no more HPUX 9 mans nor boxes...

Good luck

I remember also
crw-rw-rw- 1 bin bin 121 0x201306 Nov 17 1994 0m
2.0.1 is the scsi interface
.3 is the target scsi.

I wonder if you shoulnd use mkdev...
I remember now you will have to do a man of config because I remembered using config -a that creates a shell script mkdev (or alike... I gettting old...)
you use mknod for non HP device
to list major/minor you type lsdev...
Thats all
