此问题同时影响两个服务器。
如果发生了 SPARC 处理器队列阵列奇偶校验错误，则 Oracle Solaris 会因为无法继续安全运行而出现紧急情况。在极少数情况下，Oracle Solaris 可能会在紧急情况后无法成功重新引导。
要验证是否遇到此问题，请在故障管理 Shell 中运行 fmdump -eV 命令，以确认 error-condition 字段设置为 QRAP 的任何 mreg-uc ereport。例如：
faultmgmtsp> fmdump -eV 2015-10-14/09:11:42 ereport.cpu.generic-sparc.mreg-uc@/SYS/CMIOU15/CM/CMP/SCC7/CORE3 __tod-0 = 0x561e7ead __tod-1 = 0x1cee5cc0 tstate = 0x4400000402 htstate = 0x4 ehdl = 0x1fdc100000000007 tpc = 0x60000f022fac tl = 0x1 tt = 0x29 diagnose = 0x1 error-condition = QRAP reported-by = Hypervisor ps-pesr = 0x600 ps-res-err-qhead = 0x0 ps-res-err-qtail = 0x0 ps-nres-err-qhead = 0x0 ps-nres-err-qtail = 0x0 ps-cpu-mondo-qhead = 0x0 ps-cpu-mondo-qtail = 0x800000000011b340 ps-dev-mondo-qhead = 0x0 ps-dev-mondo-qtail = 0x0
运行 fmadm faulty 命令应该会显示某个核心已被故障管理软件禁用。
