Description/Recommended actions
– Check for disconnected SAS cables in the bad path. If no cables are disconnected, replace the cable
connecting to the ingress port in the most-upstream enclosure with reported failures. If that does not
resolve the problem, replace other cables in the bad path, one at a time until the problem is resolved.
– If that does not resolve the problem, replace the expansion modules that are in the bad path. Begin
with the most-upstream module that is in an enclosure with reported failures. If that does not resolve
the problem, replace other expansion modules (and the controller module) upstream of the affected
enclosure(s), one at a time until the problem is resolved.
– If that does not resolve the problem, the fault is probably in the enclosure midplane. Replace the
chassis FRU of the most-upstream enclosure with reported failures. If that does not resolve the
problem and there is more than one enclosure with reported failures, replace the chassis FRU of the
other enclosures with reported failures until the problem is resolved.
