The recommended service action for this event is to schedule replacement of the affected component(s) at the earliest possible convenience. Although the PCI Express link may be functioning, it is not intended nor recommended that the faulted component(s) remain in the system for a prolonged period of time.
SPARC T5-x systems can be affected by several CR's that cause a a failure diagnosis that can be resolved with patches.
Please see the following document:
Solaris 10 and Solaris 11 Fault Management Architecture (FMA) on SPARC T5-2 Systems May Report PCIEX-8000-YJ Major Events (Doc ID 2007819.1)
SPARC T5-2 PCIe fault events triggered by Replay Timeout errors (rto) exceeding threshold (Doc ID 1966605.1)
I/O SERD threshold values are set too low and may result in PCIEX-8000-J5, PCIEX-8000-YJ and PCIEX-8000-KP faults. (Doc ID 1617956.1)
For Fujitsu M10 platforms only, the XSCFU data should be collected and the information from the XSCF "showlogs error" command should be used to determine the resolution, in preference to using the Solaris PCIEX-8000-YJ fault diagnosis and indictment of any suspected faulty parts.
