求助N7K引擎板的PrimaryBootROM故障的问题

本帖最后由 xy411381121 于 2021-3-15 22:50 编辑
Nexus7000 C7010,版本是6.1(2)
最近在show module检查N7K的时候发现备引擎经常fail

日志显示如下:
2021 Mar 11 12:12:40 N7K_01 %DIAGCLIENT-STANDBY-2-EEM_ACTION_HM_SHUTDOWN: Test has been disabled as a part of default EEM action
2021 Mar 11 12:12:40 N7K_01 %DEVICE_TEST-STANDBY-2-PRIMARY_BOOTROM_FAIL: Module 6 has failed test PrimaryBootROM 20 times on device Primary BootROM due to error (null)
以前也遇到过引擎板fail,但诊断出来是SpineControlBus有问题,而且查看文档发现是个BUG问题,根据官网的CSCuc72466文档修改该引擎test 11的自检时间就好了,但这次我参看CSCuc72466的说明尝试修改该引擎test 6的自检时间后,当时show module,查看是到的module 6是pass,但过几天又会再次变为fail,近3周差不多就出现了3次,今天又发现,即使看到module 6 为pass,但PrimaryBootROM依旧为F。
请问这次这个应该不是BUG问题了吧,是硬件故障吗?

这应该是可忽略的问题。按照Cisco官方的说法是不需要采取任何操作:
Error Message DEVICE_TEST-2-PRIMARY_BOOTROM_FAIL: Module [dec] has failed test
[chars] [dec] times on device Primary BootROM due to error [chars]
Explanation Online diagnostics PrimaryBootROM test has failed
Recommended Action No action is required.
除此之外,也有关于这个的bug说明,问题比较难定位:
GOLD PrimaryBootROM Last failure reason always indicated (null)
CSCuf82089
Description

Symptom:
The PrimaryBootROM and/or SecondaryBootROM diagnostic tests and the reported error is reported and displayed as "DEV_UNDEF and error (null)" which makes Root Cause Analysis (RCA) difficult.
Conditions:
The PrimaryBootROM and/or SecondaryBootROM diagnostic tests fail due to an unknown and undefined error.
Workaround:
None at this time.

Futher:
有两个诊断测试,PrimaryBootRom和SecondaryBootRom,默认情况下启用。 这些测试将验证BIOS的contents 和version,并每30分钟运行一次。 已经确定,每30分钟运行一次这些测试过于激进,因为它可能会触发执行BIOS升级时暴露的缺陷。
这对交换机的正常功能没有影响。 但是,如果触发BIOS的问题的话,在此不一致的BIOS状态下关闭电源后再打开电源/重新加载交换机,则该交换机可能无法启动NX-OS,并且将需要RMA来解决。
