datamodelDB of Maintenance Suite mising issue caused by change the NMS server IP and synchronize NMS infomation

Publication Date:  2012-07-25 Views:  72 Downloads:  0
Issue Description
in County N, customer A, we installed a U2000 (V100R003SPC100) server in HP server DL580G5.
To connect the newly installed U2000 server to intranet. after we stop the NMS server, change the server IP directly, and reboot server, restart the NMS process.
the U2000 system monitor and client can not run succesfuly. then the Synchronize NMS Information was run in Maintenance Suite. after that the instance information and components together with server information are missing.

Alarm Information

Handling Process
1, open the sql server manager, the SQL server is running.
2, try to reinstall the components, fail to add any compoents
3, try to uninstall the NMS and reinstall the NMS server. failed to uninstall.
4, ask GTAC for advice.  the recovery solution are as the folow steps. (please check attached DOC for issue and handling datails.)

1,First check the configure file “widnows_net_config.cfg “, make sure the file displays the right 'SystemNic'.
2, After stop the MS services, use backup datamodelDB to recover the instance and components of MS.
3, Start MS services and client, the instances and components are back. right click the server to synchronize network configuration.
4, Restart the Maintenance suite again.
this time the server can be started normally. 
Root Cause
1, maybe the sql server are not run automaticaly
2, maybe Affter the server ip changed, when synchronize of the server can not find any server information, the Maintenance Suite just cleared the components and instance information.

we can use back up data to recover the datamodel database of Maintainence Suite.
