Boot from cd-rom and access external disk drives
Hello,
I need to run fixfdmn on a root domain. In order to do that, I have to boot from cd-rom and create the entry for the root domain under /etc/fdmns manually. I also have to create the device file using MAKEDEV while booted from cd because the device file for my root disk is not present when booted from cd. Below are the steps I have done:
1. boot from cd and exit to a shell
2. cd /etc/fdmns
3. mkdir root_domain
4. cd root_domain
5. ln -s /dev/rrzb18c
6. /dev/MAKEDEV rzb18
7. mount -t advfs root_domain#root /var/mnt
I get an error on step 7 that says something like bad address. For some reason it doesnt like rrzb18c, but that is the device shown when I'm in multi-user mode.
Do I need to do something else besides the MAKEDEV in order to access the disk drive?
System specs:
Tru64 4.0D
External disk is on a HSZ70

Re: Boot from cd-rom and access external disk drives
I am not aware of this procedure. But, I notice that in step (5) you are using the raw disk (rrzb18c) instead of the block disk (rzb18c). Change the step 5 to:
5) ln -s /dev/rzb18c
and try.
5) ln -s /dev/rzb18c
and try.

Re: Boot from cd-rom and access external disk drives
Hi,
you need a block device as BL said and you can not do a link before you create the device, so exchange step 5 and 6.
greetings,
Michael
ps. BL, see man fixfdmn. There it says, that repairing root_domain requires booting from cdrom.
