Block traffic to node during specific time period

Hi, Please see if below link could provide some help for writing time-based irule:

link text in the above link use node iso Pool

Alternative approach's (without iRule), which might work:

• use the Priority Group Activation & prefer the nodes (not under maintenance) with high priority group or
• To use the Slow Ramp Time option on Pool only if the node is down atleast once during maintenance window,..

SlowRampTime = maintenance window + buffer time say 5 minutes to let server give some time before taking load..

So the trick here is when the node goes down first during maintenance, it will send traffic after Slow Ramp Time option only..
