Re: How to create Tru64 /dev devices for DKB SCSI CDROM drives
Try this:
For dkb0:
# cd /dev
# ./MAKEDEV rz8*
For dkb100:
# cd /dev
# ./MAKEDEV rz9*
.
.
.
You mount them:
For dkb0:
# mount /dev/rz8c /mnt
.
.
etc

I have tried what you described, but still get errors
probing hose 0, PCI

Error: /dev/rz8c is an invalid device or cannot be opened.
For the character special devices I do not see the SCSI ID

What does mean the above message dkb0.0.0.12.0 has no media present or is disabled via the RUN/STOP switch ??
Could it be that my SCSI card NCR 53C810 is malfunctioning?
Could it mean that my SCSI disks are not recognized? How could I enable them?
Still I see them from the console:

Re: How to create Tru64 /dev devices for DKB SCSI CDROM drives
If you are not able to find the corresponding device name in OS or havn't tried. Pls. try the below and find the device name.
For Tru64 V4.0x
1) scu scan edt
2) scu show edt
You can see the corresponding device name for CD and then you can mount using mount command
For Tru64 V5.x
1) hwmgr scan scsi
2) hwmgr show scsi
you can check the device name and mount it.

Re: How to create Tru64 /dev devices for DKB SCSI CDROM drives
Are you really sure about 7 CDroms on port B of the scsi-bus??. It's seems more a that some devices there have the same ID or there is a Termination problem.

Re: How to create Tru64 /dev devices for DKB SCSI CDROM drives
That means CD ROM can not read the media. Could be dirty or bad CDROM drive, bad media etc.
You may also have SCSI termination problem but does not have to be.
Could it be that my SCSI card NCR 53C810 is malfunctioning?
Could be, but I do not think so.
Please send output of:
# scu show edt
Did you boot with genvmunix kernel and rebuild the kernel after adding new SCSI controller?

Re: How to create Tru64 /dev devices for DKB SCSI CDROM drives
>>>boot boot_device -fl s -fi genvmunix
after the system had been booted and it prompt at single user mode
# bcheckrc
# cp /vmunix /vmunix.dated
#cp /usr/sys/conf/SYSTEMNAME /usr/sys/conf/SYSTEMNAME
# sizer -n test
compare the new kernal file with the old one as
# diff /usr/sys/conf/SYSTEMNAME /tmp/TEST
then add the definition of the new scsi controller to the old kernal file
# doconfig -c SYSTEMNAME
then coppy the new vmunix to /vmunix
then reboot the machine, you will see all your CD-ROMs under /dev without using ./MAKEDEV.
all my best

Re: How to create Tru64 /dev devices for DKB SCSI CDROM drives
In the end I have connected the SCSI card with the 7 CD-ROM drives to an Intel Pentium Red Hat Fedora 5. And I have mounted them via Samba. This way I can access 7 CD's from the LAN.
It all went automatic. No need to do a kernel build, and much more CD formats are accepted with Red Hat than with Tru64.
