unable to interrupt boot process

[Malte Neumann]

On one of our workstations (785/C3000) running HPUX 10.20 we are for some reason (we don't know how this happened) no longer able to interrupt the boot process. I.e. there is no 10 sec. delay, it simply boots the primary path.

Is there any setting (in sam?) to change this behaviour?

700 series systems' boot sequence interruption is keyboard-driven. the 785 may enabled "secure mode", it prohibits you from stopping the boot process.
You need to disable "secure mode" first:
1. Remove/disable the hard disk drive.
2. Reboot system.
3. The system will prompt that it cannot find a boot device.
4. You may Press the Esc key.
5. In admin mode, you can disable "secure mode".

Then you may able to stop the boot sequence by pressing the escape key.

A rude solution:
Pull one HD out, power on!
When go into Main Menu, type

co
sec off

Power down and pull the HD in.
Now the 10 sec inte. will be echo!

Hi Malte

I'm not aware of any setting.
Don't know if this helps in anyway but as a work around you could issue the following command as root:
# setboot -b off

This will turn off autoboot and the machine will pause its boot at ISL. Alternatively you can use setboot (setboot -a) to boot from an alternate path if thats want you wanted to do.

Hi,
There is a command called setboot which sets the Boot path. By using setboot u modify the Primary and Alternate boot path of the system to a device which is not your root disk. So when u reboot your system it will not find the root disk on path and fails in the PDC itself. Later you can change the same.

See man setboot.
#setboot -Displays current Boot paths
#setboot -p - to set Primary boot path

#setboot -a - to set Alternate boot path

Disconnect the boot disk temporarily.

Then change the settings
