Can I reconfigure application to use FQDNs of servers instead of IPs?

I've noticed that if I go in to my Application Services > Applications > [My App] > Reconfigure > I am not able to add the servers next to "Pool: Members" by FQDN. It seems it will only accept IP addresses.

 

If I try to edit the pool by going to Local Traffic > Pools > [My Pool] > Members > I am not able to edit the pool in this menu, it says:

 

010715bc:3: The application service (/Common/DNS-Internal-VS.app/DNS-Internal-VS) has strict updates enabled, the object (Pool /Common/DNS-Internal-VS.app/DNS-Internal-Pool) must be updated using an application management interface.

 

Is strict updates something that I can disable? Or do I have to edit the application using the first method and not use FQDNs?

    Sounds like the iApp that you are using is built for addresses and does not support FQDN nodes. What iApp template are you using?
  • I am using the appsvcs_integration_v1.0_001 template provided by a F5 Solutions Architect.
  • Assuming 1. the iApp does not support FQDN 2. you are running a version of BIP-IP that supports FQDN based nodes

     

    Then you can disable strict updates on the iApp (on the properties page of the iAPP). You could then create the new nodes manually and replace the pool members. However, any subsequent updates to the iAPP would overwrite your changes and you would need to perform the same changes again.

     

    If you are running a version of BIG-IP that does not support FQDN nodes (11.6 I believe is the first release to do so), then even manually making the changes with strict updates will not truly be using FQDN. Prior releases allowed you to use an FQDN, but only during the creation process, when it resolves it to an IP and uses the address instead.
