Boot alternate from EFI Boot Manager

[BERTRAND_7]

Hi,

We have installed a plateform with HP-UX 11.23 on an rx4640 Integrity Server.

Then, we perform all the steps describe Appendix of document "When Good Disks Go Bad: Dealing with Disk Failures under LVM" to mirror the root volume.
each step was successfully performed.

Then we expect to boot from the mirror disk defined as the alternate path to check the installation.

To do so, we reset the system and interrupt the boot sequence from the EFI Boot Manager menu. Then we select the "HP-UX Alternate Boot" option to start the sytem but it send an error message that it fails with no other information.

Then we select the "EFI Shell [Built-In]" option to perform the same operation from the shell.
After changing to the correct fs (fs1:), we launch the command "hpux" which automatically starts our system with the correct parameters.
After that everything works fine.

We don't understand what information is missing to correctly start from the HP-UX Alternate Boot" option.

Regards.

Doesn't it give any message?? Boot from primary disk and check if root mirror is ok. lifls -l on both disks.

[BERTRAND_7]

I run the lifls -l on both disks and I get the same information.

I just want to remin that we selected through the EFI shell, the system starts up from the alternate disk.

The only problem is that I get the message
"Load of HP-UX Alternate Boot: 0/1/1/0.0.0 failed: Not Found" when i use the "HP-UX Alternate Boot" option from the EFI Boot Manager menu.

Any suggestion ?

hi,

The mirrored drive should be set to the High availability alternative drive.

setboot -h

not just the standard Alternative boot path with 11.23.

If this still doesnt work do the lvlnboot options again seperatly for the lvols.
lvlnboot -r
lvlnboot -s
lvlnboot -d
lvlnboot -b

I ahve seen this happen where just
lvlnboot -R was done and it didnt update properly.

Hi,

As recommended by Andrew, I set the mirrored drive for High Availability alternative drive
setboot -h 0/1/1/0.0.0

When I run setboot to display the result, I get the same information for "HA Alternate bootpath" and "Alternate bootpath".

Once again I reset my sytem, and use the "HP-UX Alternate Boot" option from the EFI Boot Manager menu.
Still fails.

Then I use the "HP-UX HA Alternate Boot" option from the EFI Boot Manager menu and the system starts up correctly.

That's fine. Thanks Andrew.

Just for my knowledge, what is the difference between "HA Alternate Boot" and "Alternate Boot" ?

hi,

its just another option HP/Intel have placed in there from what I know,

this allows you to have the two mirrors as boot paths and still have the cd/dvd as aboot path aswell.

CD/dvd should be set to the alt path so you can just select the cd from EFI to boot without searching for devices or looking through the menus as you did for the mirroed drive.
