In some rare circumstances, the High-Speed Bridge (HSB) device might drop off the PCI bus, resulting in the BIG-IP system not being able to pass traffic. However, no high availability (HA) failover condition is triggered, so the BIG-IP system stays active.
No failover to standby unit after this error condition, causing site outage.
HSB drops off the PCI bus. This is caused in response to certain traffic patterns (FPGA issue) that are yet to be determined.
None.
Now the active BIG-IP system fails over to the standby when HSB on the active unit drops off the PCI bus.
