现场设备是: nexus c7010
show module显示如下信息:
SWITCH_A# show module

slot 5、6是引擎,现在slot 6是主引擎,但是为什么Online是fail的呢?会有什么影响吗?

您好!
根据描述以及diagnostic输出,应该是已知bug:
CSCuc72466 Spine Control Bus fail in both active and standby
Symptom:
SpineControlBus diagnostic test failure on active and/or standby supervisor.
Conditions:
This happens when active and standby supervisors run the Spine test at the same time.
Workaround:
Configure the following for the module in question (only one SUP, even if both have the error):
NOTE: Test 11 is for Sup1, Test 10 is for Sup2
N7K(config)# no diagnostic monitor module 5 test 11
N7K(config)# diagnostic clear result module 5 test 11
N7K(config)# diagnostic monitor interval module 5 test 11 hour 0 min 0 second 31
N7K(config)# diagnostic monitor module 5 test 11
N7K(config)# diagnostic start module 5 test 11
This workaround will decrease the possibility of this condition occurring but does not guarantee that the diagnostic failure will never be encountered. For that the customer needs to upgrade to the proper code with this fix.

bug中的workaround,把主备引擎的Spine Control Bus自检项的间隔调开,避免主备引擎的Spine Control Bus 同时自检。但是,这只是降低概率,不能彻底解决。彻底解决,需要升级至bug的修复版本。参见bug链接。
谢谢!

神奇 了,你这个应该是主引擎啊,fail 是不是系统显示错误?可以的话下班时间主备切换一下,再切回来看看!

show module设备能够识别主备引擎,主备引擎的指示灯都是正常的,设备也没有报什么异常日志信息,而且15年年底就出现这个问题也没有影响业务。我在网上查了下,应该是由下面的诊断失败引起的,
#show diagnostic result module all detai
Test results: (. = Pass, F = Fail, I = Incomplete,
U = Untested, A = Abort, E = Error disabled)

11) SpineControlBus E

Error code ------------------> DIAG TEST ERR DISABLE
Total run count -------------> 1287818
Last test execution time ----> Sat Dec 5 06:48:16 2015
First test failure time -----> Mon Sep 22 15:01:43 2014
Last test failure time ------> Sat Dec 5 06:48:16 2015
Last test pass time ---------> Sat Dec 5 06:47:46 2015
Total failure count ---------> 33
Consecutive failure count ---> 1
Last failure reason ---------> Spine control test failed
Next Execution time ---------> Sat Dec 5 06:48:46 2015

XBar 1 2 3

______________________________________________________________________

然后我按照最近一次故障出现的时间查找日志,发现确实有几条信息出现,如下:
2015 Dec 5 06:48:16 SWITCH_A %DIAGCLIENT-2-EEM_ACTION_HM_SHUTDOWN: Test
has been disabled as a part of default EEM action
2015 Dec 5 06:48:16 SWITCH_A %DEVICE_TEST-2-PWR_MGMT_BUS_FAIL: Module 6 has failed test SpineControlBus 20 times on device Power Mgmt Bus on slot 12 due to error Spine control test failed error number 0x00000002
2015 Dec 5 06:48:16 SWITCH_A %MODULE-4-MOD_WARNING: Module 6 (Serial number: JAF1536BFHJ) reported warning due to Spine control test failed in device DEV_UNDEF (device error 0x2)
2015 Dec 5 06:48:16 SWITCH_A %VSHD-5-VSHD_SYSLOG_CONFIG_I: Configured from vty by admin on vsh.28251
但是就出现这一次,从那以后就没再出现这个
关于这个SpineControlBus作用是啥我就不清楚了。
好像是说诊断失败,还跟背板有关,但是具体有什么影响、怎么解决我还是不懂。还请大神指教!
