Jennifer,

    You are specifying that on a system already registered in cobbler that you want to be able to switch the BIOS setting for boot source?  As Alvin mentioned, at the moment this is not possible, as an alternative you could script it yourself... I am however, curious to understand the reason for your needing this functionality provided that you can tell me.  

    I am not a developer working on cobbler... not yet anyway,  however, since I am a heavy user of cobbler and follow this list very closely I was curious about your post...

    The reason why I am curious is mainly due to the fact that once your server is set to boot from PXE you shouldn't need to have it changed.   Unless you are pre-defining your servers in cobbler and then using it to deploy each one?   

    My set up uses the default system settings to install a base operating system, automatically register the system to cobbler, determine the system type (virtual or physical) , reinstall the correct OS/Profile, and then configure it automatically.  This allows me to get my servers from the factory preset to PXE, press the power button and go.

    I would like to see various functionality like this integrated into the cobbler framework however... of particular interest is turning on and off CPU components i.e. hyperthreading or virtualization at the BIOS level.

Howow would you suggest going about that...

Aside from somehow inserting some manual bit into the python code to do this?  And even then, what and where?

And why doesn't the CLI work for things like this...?

cobbler system edit --name=test123 --netboot-enabled=true

cobbler system reboot --name=test123

Does not produce a netboot.  But ipmitool wiil.

When I do try it that way, I don't even get anything valuable in the logs if it's failing to try to set a netboot.


Seems like this has been solved or documented by someone somewhere.

It was my impression that fence is just to shut a machine down as part of the HA/clustering toolset.
All the other features are just added extras that are not needed as part of the primary function.

The features from man include on,off,reboot,status,diag,list,monitor.

There is no "set to boot from PXE".
I believe that you will need to do this manually.

Just having some woes with making fence_ipmilan work with some Supermicro servers (Don't say use the supermicro IPMI Tool, we're trying to get around that.)

The problem is, using fence_ipmilan, we can initiate a boot (off then on) from the web GUI, or from the CLI via...


# cobbler system reboot --name=test123

task started (id=Power management (reboot), time=Wed Aug  5 09:28:15 2015)

*** TASK COMPLETE ***

So that's great.  My real question comes from the fact that I can't make cobbler set these machines to reboot via the Web GUI to Netboot/PXE.  It just seems to never issue the right command via fence_ipmilan (which actually uses IPMITOOL)

I can do it fine in IPMITOOL:

ipmitool -H 192.168.1.5 -U user  -I lanplus -P password chassis bootdev pxe
ipmitool -H 192.168.1.5 -U user  -I lanplus -P password chassis power reset

And the system reboots into PXE boot mode.

So is there something I have to mangle in /etc/cobbler/fence_ipmilan.template?

Something Else?

All help is appreciated.

Thanks.

JLP
