If an iRule refers to a pool by the full path, /folder/pool name, the virtual server status does not reflect the pool's status.


While traffic can still be served to the pool_member despite the virtual server status, for changes at the virtual server level (for example, route health injection), the system needs a reliable virtual server health status.


This occurs when the iRule uses the full path name for the pool.


Remove the folder path and reference the pool by name only within the iRule.

Fix Information

If an iRule refers to a pool by leaf name (without the full path), the virtual server status now reflects the pool's status.
