Where LTM's getting its configuration?

Hi F5'ers,

 

I'm running 10.2.2HF3 in HA.

 

Manually I've changed /config/bigip*.conf, specifically, removed references and configuration of non-Common Partitions.

 

There's a known fault in pre-10.2.3 that prevents "b import" and I guess it applies to "b load", so, I know that won't work. However, my understanding is that "bigstart stop/start" or reboot should reload using /config/bigip*.conf, but it doesn't!! The reloaded configuration still looks like old-configuration (ie. with Partitions), even though "grep -i partition /config/bipip*.conf" shows nothing except Common!!

 

Where is LTM getting its configuration?

 

R's, Alex

    Hi Alex,

     

     

    What error do you get when running 'b load'? That should work to force a reload of the config from file into memory.

     

     

    Else, you can remove the binary config file cache (this requires an outage though):

     

     

    bigstart stop

     

    rm /var/db/mcp.*

     

    bigstart start

    Hi Hoolio, thanks for answer, I was about to post the information you included, kudos to F5 support engineer.

     

     

    > What error do you get when running 'b load'? That should work to force a reload of the config from file into memory.

     

     

    I believe (and F5 support engineer tentatively agreed) that SOL11933: "A VLAN cannot be moved between partitions during a single configuration file import operation" is not limited to just the import but also to "b load" and "b verify load".

     

     

    Just for completeness:

     

    > you can remove the binary config file cache (this requires an outage though)

     

    or (as per sol13030) "touch /service/mcpd/forceload" will also do it.

    Thanks for clarifying what the issue was. I figure a bigstart stop/stop is faster than a reboot :)
