FAQ-How can we know when active and standby SCCs switching happened

Publication Date:  2012-07-25 Views:  43 Downloads:  0
Issue Description


Engineer wants to know when active and standby SCCs switching happened. How can we find the active&standby switching record in the log files?

Alarm Information


Null


Handling Process


We can know it by analyzing the OCPLOG.txt or HBU.LOG file.

1.In OCPLOG.TXT file, we can find  "ProcMSSwitch MSG_HBU_SMOOTH" record which means the standby SCC board switched to active state, and "NotifyACT2STDBY"  record which means the active SCC board switched to standby state.

Example:

ProcMSSwitch MSG_HBU_SMOOTH 0 0 0 2011-7-12 16:2:16

NotifyACT2STDBY 0 1 2011-7-12 16:39:59

2.In HBU.LOG file, we can find  "HSC SWITCH slave --> master" record which means the standby SCC board switched to active state, and "HSC SWITCH master --> slave"  record which means the active SCC board switched to standby state.

 Example:

NO:921 TIME:2011-7-12 16:2:3 MODID:0x29 INFO:ErrCode:0xffffffff FileName:hsc_msg.cpp Line:650 Info:HSC SWITCH slave --> master

NO:1127 TIME:2011-7-12 16:39:57 MODID:0x29 INFO:ErrCode:0xffffffff FileName:hsc_msg.cpp Line:375 Info:HSC SWITCH master --> slave

 From above records, we can know:

This SCC board was switching to active state at  2011-7-12 16:2:3 and  was switching back to stanby state at 2011-7-12 16:39:57.

Root Cause


Null


Suggestions

When the active scc board switches to standby state, it will resets itself. So we can find a  "Init OCP Log OK" record after "NotifyACT2STDBY" record.(see case:SE0000531254)
OCPLOG.TXT is in the /ofs2/log/ directory of SCC.
HBU.LOG is in the /ofs1/log/ directory of SCC.
It is useful when we do the troubleshooting.
