Boot Tru64 from bootable tape fails

Hi all,
I have an AlphaServer DS25 running Tru64 V5.1 B. Because Unix freezes while loading, I want to boot it from another media rother that HDD to correct any popssible error. So I create a bootable tape from another machine running Tru64 and when I issue the command:

>>>boot dva0 <-|

the system display the message:
(boot failed from dva0.0.0.1000.0.)

I don't know why it does not boot from the tape. Have I to issue some more parameters?
Anyway, is there any possibility to create a bootable CD? So that I may have just a little kernel and perform mounting of some filesystems?

Thank you.

Hi,

you could boot from the installation disk and abort the installation. You will then have a shell and can mount selected file systems.

greetings,

dva0
Is it really a tape device?

As far i can remember, dva0 is a floppy drive, the take device should be mk* device.

You said "freezes while loading". You can try boot the generic kernel or in single user to troubleshoot the problem.

boot -fi genvmunix

boot -fl s

Por que hacerlo dificil si es posible hacerlo facil? - Why do it the hard way, when you can do it the easy way?

Re: Boot Tru64 from bootable tape fails

I would first try to boot sinfle user mode.
>>>boot -flag 0 (or boot -flag s)
Then I would do
# mount -a
to mount all file systems.
Then I would manually execute scripts in /sbin/rc3.d one by one.
If single user boot is not possible, I would try >>> boot -file genvmunix
Boot tape made on another machine may not boot on your machine.

Thank you for your replies.
In fact, I solved this problem by booting from installation CD and using the shell that was supplied there.

Thank you.
