A number of capabilities were added to AIX 7.2 TL 3 related to improved MPIO detection of failed paths.
AIX MPIO has capabilities to detect transitory transport errors and aggregate those to determine when a path should be failed. These are paths that usable, but experiencing recovered or temporary errors at a rate which causes them to impact system performance. This capability to detect "sick but not dead" paths and mark them as failed is limited to analysis of transport errors. This RFE is related to expanding this capability to include a broader set of device specific errors in the analysis of when a sick path should be marked dead.
I'm also very interested in improving AIX MPIO and I would gladly vote for this, but I can't access the PMR. So please add a brief description to this RfE.
