Boot from cd-rom to access disk drives

Hello,

I've booted a Digital Unix 4.0D system from cd-rom and I need to access the system's disk drives. I need to run the fixfdmn utility on the root domain so I need to create the root domain in /etc/fdmns.

Could someone tell me how to access my system's disk drives after I've booted from cd-rom?

I have searched all over Google and this forum and found nothing.

Please help.

Thanks,
Adam

Ok,

I've managed to access internal disks when booting from cd-rom, but what I really need to do is access an external disk.

When I'm booted up in multi-user mode, the device name for the disk I need access to is /dev/rzb18c. When I boot from cd-rom, this device is not listed under /dev. I ran the following command to create the device:

/dev/MAKEDEV rzb18

Now there is a rzb18c listed under /dev so I do the following:

mkdir /etc/fdmns/clnc_domain
cd /etc/fdmns/clnc_domain
ln -s /dev/rzb18c

I use the following command to try and mount the disk:

mount -t advfs clnc_domain#clnc /var/mnt

...and I get an error that says something like bad address.

I was able to succesfully mount an internal disk after creating the entries in /etc/fdmns.

Am I missing some steps after the MAKEDEV?
