Details

The Message ID:
SUN4V-8000-63
indicates a diagnosis has determined that one of the cores in the
multi-thread processor contains a faulty resource. The diagnosis determined
the impact of the fault is localized to a single thread that
is being removed from service. However, the faulty resource is shared
by all four threads in the core. There is the potential
for the other threads sharing this resource to experience an error.
It is recommended that the system administrator contact Sun support and
arrange for the replacement of the affected component.
The physical thread number reported by the fault manager may not be the
same as the logical thread number reported by Solaris. In the example
below, the physical thread number is 8 while the logical thread number
is 4.
