Changing parameters in APIC-EM server

Trying to change some of the parameters regarding the OS running the APIC-EM, like:

• Network interface MTU size
• Adding authenticated NTP

It looks like the configuration is working but after restarting the server the APIC-EM does not start, the cluster IP is not responding and running the "reset_grapevine" is removing all the configuration .Added and restoring the default configs. Is there a way to change this configs without destroying or disrupting the server functionality.

When you say you do reset_grapevine, do you do just "reset_grapevine" or "reset_grapevine clobber"..

The first is an interactive op and you will have to answer the questions asked in order to preserve the APIC-EM DB states and values in it. Clobber will literally clobber it and delete the APIC-EM DB altogether.

Doing "reset_grapevine" and answering "no" to all the questions, the thing is that this procedure resets the /etc/ntp.conf file where added the NTP authentication for example.

1.4 will allow you to do a manual resync too.
