The vs-index field on virtual servers differs on each blade in a chassis.
The recently created virtual server holds different vs_index across blades (typically, the virtual servers differ by one, when compared with the active blade). From that point on, every newly created virtual server carries that inconsistency, so that vs-index is set differently on each blade in a chassis.
This occurs on chassis systems when creating a virtual server on a multi-blade VIPRION and on multi-blade vCMP guests.
Follow the procedure in SOL13030: Forcing the mcpd process to reload the BIG-IP configuration (https://support.f5.com/kb/en-us/solutions/public/13000/000/sol13030.html) to clear the configuration cache and reload configuration after reboot.
The vs-index is now the same on each blade in a chassis on a multi-blade VIPRION and on multi-blade vCMP guests.
