insf question?

[Ronaldinho]

I have a problem with my tape drive.
When I do an ioscan –fnC tape the device was showing up but there was no device files showing
ie.
/dev/rmt/0m
/dev/rmt/0mn
etc..


so I ran the command insf –evC tape which changed the output of ioscan but now the /dev/rmt/1m
/dev/rmt/1mn

etc..

how can I get the system to see /dev/rmt/0m as this is what I need for backup scripts that I use to write to tape?

[Ronaldinho]

please note there was a formatting problem with my question avove.
the commands should be
ioscan -fnC tape
and

insf-evC tape

Shalom,

I recall tape drivers are built as follows:

insf -e

thanks for the quick reply Steve.

when i rebuilt it with insf -evC tape it rebuilt the tape drivers but as /dev/rmt/1m files and not /dev/rmt/0m as i require.
do you know how to change this?

Hi,

The device files created by insf are as the system sees the devices through the corresponding path, thus when you ran insf the device files for tape drive as seen by the system were created - depending on the path - even though I believe that the 1st tape device usually is named as /dev/rmt/0m etc.
But now the only solution I can see is to modify the scripts to point to this device.

Hi Ronal:

The number of de /dev/rmt... is the number of de Instance.

Try make the file yourself with:

mksf -I ...

view man mksf for help

best regards

Just rename the file to be what you want:

mv /dev/rmt/1m /dev/rmt/0m

Your systems "remembers" another tape drive.

Did you changed something? The drive or the port connected to or just the SCSI ID?

You may remove the tape dependend device files and run insf again.

Thanks Guys.
i re-worte the script to accept /dev/rmt/1m
But torsten i will try your solution next time i see this problem.
