Problem Description
One day an operator's maintenance personnel wanted to modify a set of non-gateway network element OSN3500 equipment to become a gateway network element, in accordance with the method of modifying the network element ip modification, but always unsuccessful, and then query the version of the R3 (5.21.13.47p01), query its nodeid is 129.9.0.1, and want to modify the gateway network element ip address is 129 .9. 11.15, two ip addresses within a network segment so that can not modify the normal network element ip address. 129.9.11.15, the two ip addresses are in a network segment, so it is not possible to modify the ip address of the gateway. The engineers of the partner were allowed to modify the nodeid of the gateway, but after the modification was completed, the soft reset of the main control board reported that the gateway was in the state of security alarms. The alarm disappeared after the full-volume download of the service to the network element on site.
Alarm informationne-install
Processing1, R & D from the return of the data in the modification of the network element nodeid a few days before someone manually delete drdb database operation; resulting in drdb database no data; so when the main control board soft reset up after the report network element is in the state of security alarm.
2, OSN3500 equipment database backup mechanism:
As the OCP data using incremental backup, that is, only the new configuration data will be stored to the DRDB, in the network element cycle backup will be DRDB in the data backup to flash. As the data in FDB0 was also cleared during the clearing operation on 2007-12-26, the network element was automatically reset after modifying the Nodeid 8 days after the incident. After resetting, the network element restored the default configuration, and thus the network element entered the installation state.
3, mdb data is backed up to drdb, and drdb data is periodically backed up to fdb, real-time backup to nvfldb, the process of backing up from mdb to drdb is an incremental backup method.

Root CauseDatabase anomaly.
Recommendations and SummaryThe configuration must be re-downloaded after manually deleting the database, otherwise it will leave the network element in an an state when the master resets up.
