HASH PERSISTENCE

It sounds more like you're having troubles with the load balancing within the pool itself than a problem with the iRule.

 

 

Are you receiving any errors in your /var/log/ltm log when passing traffic through the Virtual with the Rule enabled?

 

 

I'd try toying with the load balancing settings in the pool to see if you can get some traffic to route to the other host.

 

 

If you do suspect an error in the iRule after checking out the pool settings and testing things, then I'd start by adding some log lines in your iRule to let you know what's going on at each logical step of the process.

 

 

HTH,
