Need help with the config push

Hi All,

 

I have a question about the LTM configuration. I have a pair of F5 LTM's with Sync issues, I wanted to manually ( Load the config from the Active box) sync the config to the standby box , before I fix the sync issue. Here is my plan,

 

  1. save the bipip.conf file on the Active box (tmsh save sys config file var/local/bigip_latest.conf)
  2. Move this file to the standby unit to the location var/local
  3. Take the backup of bigip.conf on the standby unit (tmsh save sys config file var/local/bigip_backup.conf).
  4. Verify the latest config which has been copied from the active box (tmsh load sys config file bigip_latest.conf verify)
  5. Then load the file , tmsh load sys config file var/local/bigip_latest.conf.

I have two questions , 1. Do i need to perform the merge OR just a load tmsh load sys config file var/local/bigip_latest.conf OR tmsh load sys config file var/local/bigip_latest.conf merge

 

  1. Do I also need to move the bigip_sys.config? , If yes , how can I push both the config file.

Thanks, SR

    You are taking bigger steps for a simple sync. In general, when you make a config sync from Active to Standby, you would require to do,

    (Active)(/Common)(tmos) run cm config-sync to-group device-group-failover

    When this is run, the Active configuration gets saved onto the specified device group. In the event the standby configuration has the latest, it would tell you that standby is having the latest config and would requires to do from B to A. But you would know that Standby might have the latest, in this event, either you can do a force overwrite or make a dummpypool in the Active and then give the above command. This indicates the HA pair, that latest configuration changes has happened in the Active LTM.

    Also its not advisable to copy a bigip.conf file of one box and load it on another box. There would be some parameters like bind-pwd which would differ.
