Boot HP-UX

[ben dhib]

Hello,
I have a functional HP-UX 11.0 system on HP 9000. What I want to make is to have two different boots during starting up.

My need is the following one:
I have two server who have the same material configuration and the software.

The first server is functional on which I have a software of messaging and connected on the network, A procedure of BACKUP is made every night on this server N°1.

I want to use the second server as a BACKUP of the first one, for this case of breakdown on the first server, I can use it of the second.
What I want to make is to be able to start the second server with two different manners.

Boot 1: starting up without taking into account network parameters, nor the launch of the messaging
Boot 2: d normal starting up

How I can make either create the a second boot

Hello ben!

My recommendation is to have an image mirror of the boot drive in a separate location, if the original vg00 goes down you could always boot from the other disk. You could mirror the vg00 and then split the mirror.
About boot option number one you could interrupt the boot process and then start the system in single user mode.
About the boot option number two just let the system boot up without interrupting the boot sequence.

Regards,

Jaime.

Thanks Jaime,
about your recommandation, i need tohave 2 server beacause i think if the first server is down completely, i can use the second one to replace and allgose well.

about the boot one, are you sure that the signle user mode dont start any application or any other services ? what about the network ?
in the first Mod i want to start the server with a second IP address not the one configured in the second mod.

Best regards

Maybe MC Service Guard to build cluster is the solution for you.

Yes single user mode will start the server with minimal services, if you need more you can mount other filesystem to be able to perform more things, or change to the next run level.

Remember this solutions are not the best, becuase the changes performed in one server never replicate to the backup one, the best thing to use here is Service Guard but it´s an expensive solution.

Jaime.
