Interrupting boot to get to EFI

[KPS]

Hi,

I have an rx8640 IA-64 system running 11.23 that has several vPars within an nPar. We're trying to reboot each vPar to have the ability to interrupt the boot at the EFI Shell to get interactive with that. We see the message to interrupt the boot and we try to, but it seems the boot process just continues on and boots the kernel without giving us the chance to get into the EFI. We checked and turned off Fastboot thinking that was it as it was turned on, but we have tried another boot since and still the same symptoms of not being able to interrupt the boot.

Could anyone tell us what else we need to change or look at on the vPars to allow us to interrupt the boot?

Thanks in advance,

This is not possible!

You only see the EFI output, but you cannot interact - this is normal!

What you are going to do?

If you want to go to single user mode for example, you have to specify the option in the vparboot command.

Thanks Torsten,

What we are trying to do is to test booting off the Alternate Boot Disk. We intended to interrupt the boot and get into the EFI to choose the Alternate Disk.

Would you know of any other ways to handle this on the vPar configs?

From Manual:

To boot winona2 using the alternate path:

winona2# vparboot -p winona2 -B alt

Thanks Torsten, I think we're good to go now.

Thanks,
