1 [Failure phenomenon]

When the Huawei OSN1500 device at a sitewas upgradedfrom V1R9C04 to V1R10C03 , after the activation was completed, the NE_INSTALL alarm was reported on the main control board, and all the cfg commands were not available, and the error messagewas returned.

2 Alarm message

NESTATE_INSTALL

3 Cause Analysis

The database is corrupted, resulting in unsuccessful validation of the network element data, leading to the report of this alarm.

4 [Processing

Answer.

Erase the database, reset the master and download the network management data.
Steps to erase database:
1.Execute the following4commandsone at a time
:sftm-delete-file:82, "ofs1/prevpdt"
:sftm-delete-file:82, "ofs2/prevpdt"
:sftm-delete-file:83, "ofs1/prevpdt"
. sftm-delete-file:83, "ofs2/prevpdt"
2.Soft reset the master
:reset
Wait for the master to come up and then perform the following steps.
Erase the database, reset the master and download the network management data.
Steps to erase database:
1.Use the following commands to stop the automatic and cycle backup of database:
:dbms-set-autobackup:disable
:dbms-set-cyclebackup:disable
2. Use the following commands to delete all database files
:dbms-delete-database:all ,drdb,master
:dbms-delete-database:all,fdb0,master
:dbms-delete-database:all,fdb1,master
Backup cleanup command:
:dbms-delete-database:all,drdb,slave
. dbms-delete-database:all,fdb0,slave
:dbms-delete-database:all,fdb1,slave
3. Use the following to check if the database is cleared.
:dbms-get-list:drdb
:dbms-get-list:fdb0
:dbms-get-list:fdb1

If the clearing is completed, it should return"failed! cmd:0x3005 error:0x9205 NSERR_DBMS_HEAD_CHECK_ERROR"; otherwise, it is necessary to issue a command to clear the database again (forR8and below, if the above clearing command is successfully executed, you can ignore the step3and directly execute thestep4).
4.Soft resetStandby master,soft reset the master after10s.

First use the command:hsc-get-ms-info;to check the status of master and backup.

:cfg-reset-board:slavegsccId,soft (slavegsccIdis the standby masterslotID)
wait 10 seconds
:cfg-reset-board:mastergsccId,soft (mastergsccIdis the standby masterslotID)
5After the master is reset, use the following commands to turn on automatic database backup and cycle backup:
:dbms-set-autobackup:enable
:dbms-set-cyclebackup:enable
6. The network administrator sends down the configurations of the network elements, and checks whether the service is normal.
7.Query the status of the master and backup
:hsc-get-work
:hbu -get-backup-info
:cfg-check-ocphbu .

5 [Suggestions and Summary

For HuaweiOSN1500network elements that are in the installed state and are caused by database corruption, you can use the above steps to wipe out the database, and then reissue the configuration and restore the database again.
