此问题仅影响 SPARC M7-16 服务器。
如果 PDECB 编号 0、1、2 或 3 上的 ECB 触发，则拥有相应 CMIOU 的主机将执行关开机循环。如果在关开机循环过程中主机重新启动，则 DCU0 和 DCU1 上的所有组件都会被排除在外。
要验证是否遇到此问题，请在主机控制台上检查以下消息：
host-name-pd0 console login: 2015-11-03 11:35:17 SP> NOTICE: Fatal error occurred. Collecting diagnostic information. 2015-11-03 11:40:03 SP> NOTICE: Abort boot due to /SYS/CMIOU1. Power Cycle Host 2015-11-03 11:42:38 SP> NOTICE: Exclude all of /SYS/DCU0. Reason: Not enough power supplies 2015-11-03 11:42:38 SP> NOTICE: Exclude all of /SYS/DCU1. Reason: Not enough power supplies
类似地，如果 PDECB 编号 14、15、16 或 17 上的 ECB 触发，则 DCU2 和 DCU3 上的所有组件将被排除在外。
解决方法：无。
恢复：如果发生此问题，则会针对该 PDECB 及其相应 CMIOU 记录一个 fault.chassis.voltage.isolated 类的故障。
启动故障管理 Shell。
-> start /SP/faultmgmt/shell Are you sure you want to start /SP/faultmgmt/shell (y/n)? y faultmgmtsp>

在 Oracle ILOM 中，有些电源将从此主机的电源列表中消失。如下面的示例所示。
-> show /Servers/PDomains/PDomain_0/System/Power/Power_Supplies
/Servers/PDomains/PDomain_0/System/Power/Power_Supplies
Targets:
Power_Supply_6
Power_Supply_7
Power_Supply_8
Power_Supply_9
Power_Supply_10
Power_Supply_11
Power_Supply_12
Power_Supply_13
Power_Supply_14
Power_Supply_15
...
->
在几分钟之后，所有电源应该重新出现在列表中。如下面的示例所示。
-> show /Servers/PDomains/PDomain_0/System/Power/Power_Supplies
/Servers/PDomains/PDomain_0/System/Power/Power_Supplies
Targets:
Power_Supply_0
Power_Supply_1

Power_Supply_9
Power_Supply_10
Power_Supply_11
Power_Supply_12
Power_Supply_13

当电源在 Oracle ILOM 中重新出现时，重新启动主机。之前排除的 DCU 现在应该已包括在内。启动服务调用以解决 PDECB 上的故障。
