Hi,

Re: unable to stop at EFI shell of vPar

Im not sure if this is relevent, however I had a similar problem booting OpenVMS blade, i.e. boot would start immediately when the Boot Manager screen appeared.

Problem was EFI variable AutoBoot was set to "ON", and delay was set to "0". So blade immediately went to boot from the first item on the booot options list.

I had to physically remove all of the viable boot options, including the internal boot disk. Reset. The system then tried (and failed) on every option on the list until it came to the "EFI Shell" option.

To check settings,

fsx:> autoboot
Autoboot: ON
Current Timeout is : n seconds
Number of retries is : m

Now either turn off autoboot

fsx:> autoboot off
Autoboot: OFF
Number of retries is : 0

or if you want it ON, set delay, in this case (10) seconds

fsx:> autoboot 10

For full information check

Shell> help set autoboot

Probably not applicable to your problem, but who knows!

Re: unable to stop at EFI shell of vPar

If I understood the question correctly, this is normal.

The EFI shell is a firmware-level feature.
When you're running a vPar system, the EFI shell is used only to start up vpmon. A vPar does not have an EFI shell: only the actual hardware has that.

If you need to access the EFI shell, you must stop *all* vPars on the system, so that the vpmon can be stopped and the entire system rebooted.

Re: unable to stop at EFI shell of vPar

A vPar cannot stop at EFI level, but you can initiate a boot to single user or a different mode from another running vPar with -o options.

Hope this helps!
