A virtual server which is actually down and should show red is reported as up and shows green.
The WebUI cannot be used to reliably assess the status of Wide IP members (virtual servers).
This issue happens when a virtual server is marked down by the system due to inheriting the status of its parent link. Note: This issue only affects Link Controller systems, and not DNS/GTM systems.
Use the tmsh utility in one of the following ways to inspect the status of Wide IP members: # tmsh show gtm pool a members # tmsh show gtm server virtual-servers
