Publication Date:  2013-01-25 Views:  507 Downloads:  0
Issue Description
There is a new site in Z country, enginner installs the windows server2003 system, then he installs SMC. And he found after he create a new GK, and check every configuration is correct. but GK status is disconnect. Like this:
Alarm Information
Alarm is disconnection in Switch Centre system.
Handling Process
1. Operate system version is server2003 R2 SP2, SMC version is 2011.11 special network version. Version is correct.
2. When checking the log of GKM, a prompt:
     20:52:47  [CIM_MultiGKManageInfoSet.cpp][421 ]  No defined GK in DB!
     20:53:28  [GKMSvr.cpp   ][1322 ]  GKM UI connnected. Serial:17244
     20:56:47  [GKMSvr.cpp   ][1322 ]  GKM UI connnected. Serial:10562”
     So, we can eliminate database issue.
3. We try to reboot the pc, but we found the SwitchCentre and SwitchManager service cannot stop, only after we turn off the gksvr.exe, the service can be stopped and rebooted.

4. When checking servers, we found SNMP Service/SNMP Trap Service are running. Because of SNMP service and SNMP Trap service and GK service are the same, result in GK cannot run.

After we stop SNMP and SNMP Trap, we found GK is online:
Root Cause
1. GK software and operating system are not compatible.
2. GK disconnect with database problem.
3. GK operation port is used by other device in this network.
When we found GK is not online, we can check if the service of SNMP and SNMP Trap are running, if yes, just stop them two.
