Abstract
A mechanism is provided in a data processing system comprising a processor and a memory, the memory comprising instructions that are executed by the processor to specifically configure the processor to implement an initiator entity in a symmetric split-direction connection. The initiator entity generates a custom keepalive command and sends the custom keepalive command to a target entity via the symmetric split-direction connection. Responsive to the initiator entity determining a number of consecutive acknowledgement commands received in response to custom keepalive commands exceed a first threshold, the initiator entity reports the symmetric split-direction connection as sufficient. Responsive to the initiator entity determining a second number of consecutive keepalive commands sent without receiving an acknowledgement is greater than a second threshold, the initiator entity reports the symmetric split-direction connection as insufficient.
