Description

When Neptune driver detects an error, it may generate 3 ereport (invalid_state, service_lost and service_restored). Where invalid_state is posted by ddi_fm_ereport_post(), service_lost and service_restored are posted by ddi_fm_service_impact(). After receiveing certain number of ereports, the FMA diagnostics engine generates a new entry in the fault log. However, the fault entry does not always contains the DETAILED information carried ONLY by the inval_state ereport. Instead, often times the "fmdump -eVu uuid" command shows the information from service-lost or service-restored ereports which do not contain the detailed informative about failure). We want the FMA diagnostics engine always record the information from the ddi_fm_ereport_post and never record the infomation from ddi_fm_service_impact. This will make the FMA fault log more useful.
Two "fmdump -eVu uuid" results are shown below, the first one is the one we want (inval_state), the second one is the useless service-restored/service_lost fault report
