Solution

"fault.io.pciex.device-interr" is a generic condition indicating the impacted device suffered a hardware event, additional diagnosis is required to identify the underlying cause.

Confirm the type of event which triggered this using fmdump -eVu {UUID};

# fmdump -eVu f0d7693f-1a07-e6fa-f161-d8683685bcda
TIME                           CLASS
Nov 05 2013 06:53:26.105045100 ereport.io.service.lost
nvlist version: 0
        class = ereport.io.service.lost
        ena = 0x83db6011e6700001
        detector = (embedded nvlist)
        nvlist version: 0
                version = 0x0
                scheme = dev
                device-path = /pci@380/pci@1/pci@0/pci@6/SUNW,emlxs@0,1
        (end detector)

        __ttl = 0x1
        __tod = 0x527895e6 0x642dc6c

Nov 05 2013 06:53:26.105009654 ereport.io.device.no_response
nvlist version: 0
        class = ereport.io.device.no_response
        ena = 0x83db600958000001
        detector = (embedded nvlist)
        nvlist version: 0
                version = 0x0
                scheme = dev
                device-path = /pci@380/pci@1/pci@0/pci@6/SUNW,emlxs@0,1
        (end detector)

        __ttl = 0x1
        __tod = 0x527895e6 0x64251f6

This can also be checked using explorer data;

{explorer}/fma/var/fm/fmd # fmdump -eVu f0d7693f-1a07-e6fa-f161-d8683685bcda ./fltlog

A variety of underlying events can trigger a PCIEX-8000-0A, as a result diagnosis is required to confirm root cause and identify corrective action.
