1.4 Restoring the Database and Default Settings
This section contains troubleshooting procedures for node operation errors that require restoration of
software data or the default node setup.
1.4.1 Restore the Node Database
Symptom: One or more node(s) are not functioning properly or have incorrect data.
Table 1-1 on page 1-41 describes the potential cause of the symptom and the solution.
Procedure: Restore the Database
Note When you restore the database, the following parameters are not backed up and restored: node name, IP
address, mask and gateway, and IIOP port. If you change the node name and then restore a backed up
database with a different node name, the circuits map to the new renamed node. Cisco recommends
keeping a record of the old and new node names.
Caution E10/100-4 cards lose traffic for approximately 90 seconds when an ONS 15327 database is restored.
Traffic is lost during the period of spanning-tree reconvergence. The CARLOSS alarm appears and
clears during this period.
Table 1-1 Restore the Node Database
Possible Problem Solution
Incorrect or corrupted
node database.
Perform a Restore the Database procedure. Refer to the “Restore the
Database” procedure on page 1-41.
