Device Drivers and /dev when booting new kernel

Sorry for the repeat, but I feel it necessary to add that I'm writing the
driver on a OSF1 V4.0 878 alpha for a scanner using a SCSI bus. I've
included the original post as well.

Thanks, any assistance is greatly appreciated!

Hi there,

I am working on an OSF1 V4.0 878 alpha. I wrote a device driver which I
called can. I used the steps described in Chapter 14 of the Digital UNIX
book called "Writing Device Drivers: Tutorial" to produce my Single
Binary Module and to statically configure it into the kernel.

My problem is that, when booting the new kernel, an error comes up that
says
"sysconfigtab: Device_Dir not in subsystem can"
"Device_Dir attribute does not exist"

I'm confused. I followed the steps as they were listed and one of them
required putting the attribute Device_Dir in the sysconfigtab file
fragment as follows:
        Device_Dir = /dev
and yet, it doesn't like it when booting the system. The system boots
fine, except my driver cannot be found in the /dev directory. I tried
removing the Device_Dir attribute (since it was optional the default was
/dev), and the error didn't come up while booting, but my device still
cannot be found in /dev.

Please help!
