We have an F5 LTM that uses a simple iRule that puts up a maintenance page. It has worked fine for years - until we updated from to BigIP 15.1.5.1 (from 15.1.5.0). Now when we implement the iRule, th...

Do you mean how the maintenance page can be automatically triggered during an outage, or how to deploy the configuration for the maintenance page automatically?

In the first case, you could for example do it using the Fallback Host option in an HTTP profile, which then redirects to a virtual server with something like the above iRule attached to it. In the second case, you are able to do it using iControl.

If you tell me which one you are looking for, happy to give you some further information.

  Thanks Alex!
  If you could guide me in both the scenarios, that would be a great help
  Please note, I'm new to F5 but since I'm part of automation team would like to assist my team to automate these manual steps we follow right now.
  Current process that we follow:
  Just before outage
  From F5 Console, Identify the current iRule configured, make a note
  We update the iRule with outage page related rule.
  Once implementation is over
  Update iRule back with Step2 rules.
  Intended automation
  Automation script should get the LB name as an argument
  Perform above current process steps 2 and 3
  Once implementation is over
  Will rollback the change
  Thanks in advance
