A blade on the active system crashes in a configuration containing a performance layer 4 virtual server with connection mirroring enabled.
When the crash occurs, the blade posts the following assert: 'tmm failed assertion, non-zero ha_unit required for mirrored flow' and crashes. Traffic disrupted while tmm restarts.
The chassis is configured for network mirroring within cluster. There is more than one blade installed in the system or vcmp guest. A virtual server has connection mirroring enabled and is associated with a virtual address that is not assigned a traffic-group (traffic-group is none).
Ensure that mirrored virtual servers are utilizing virtual addresses that are associated with a traffic group.
None
