Move Floating IP to /common partition

Hello. I've inherited a pair of HA devices where all self/floating IPs, save one floating IP, have been created in the /common partition. It isn't absolutely necessary, but my OCD keeps eating at me and I have to move this other floating IP back to the /common partition. I am looking for the best method to do this. Since it is a floating IP it is sync'd during config sync. Thus my thought would be to delete the floating IP on the standby, recreate it in the /common partition, and then configsync. What do you think?

 

I think the LTM is going to error on me when I try to delete the floating IP because I have existing virtuals on that network. If that is the case I'll have to modify the bigip.conf file to move the floating IP, then load/save the config on the Standby, and then configsync. Is that correct? If so, I'll have a few seconds where traffic will be queued, right?

 

  • I just tested the move on one of my test VE's running 10.2.3

    edit bigip.conf and move your self ip statement eg:

    self 10.1.1.2 {
    netmask 255.255.255.0
    unit 1
    floating enable
    vlan SOME-VLAN
    allow default
    }
    

    from

    shell write partition MyPartition
    

    to the Common partition, so insert it under

    shell write partition Common
    

    and then load the changes

    tmsh load sys config
    

    make sure you backup before doing this though 😛

  • What version of software are you running?

     

    I have moved objects around partitions in the past by editing the config files. Do you have a dev/test environment where you can trial this first?

      This is version 10.2.2. I have test VEs, but only version 11. Since partitions work differently I don't have a great way to test.

      Thanks Ryan. Good to have some verification. Down to my last pair of v10s which is good, but don't have a test area any longer for that version.
