The Low Impact Path Probing (LIPP) feature can be turned on or off using the vxdmpadm settune command:

# vxdmpadm settune dmp_low_impact_probe=[on|off]

Path probing will be optimized by probing a subset of paths connected to the same HBA and array port. The size of the subset of paths can be controlled by the dmp_probe_threshold tunable. The default value is set to 5.

# vxdmpadm settune dmp_probe_threshold=N
