Opened: Feb 24, 2025

Severity: 3-Major

Symptoms

Disabling a pool or virtual server that is referenced by a pool member affects how pool <poolname> selects a response, but [active_members <poolname>] still returns a value that ignores these status effects.

Impact

Unable to manage availability by disabling the pool.

Conditions

-- GTM pool -- An iRule that checks the available_members of the pool is greater than zero before selecting the pool -- Disable the pool The pool is still selected for client queries to the wideIP Logs show that the available_members is equal to the number of pool members, even though the pool is disabled.
