Description of the problem

When the SEP interface board EU08 of the Huawei OSN3500 device is replaced with OU08, the original EU08 single-board logical board cannot be deleted, and the single-board commands reported by the U2000 network management fail to be executed correctly, and the command line query on the site reveals that the name of the logical board in the slot that has been replaced with the single-board of OU08 is displayed as 09 C5, and the check of deleting the single-board using the command line is reported as :failed! cmd. :0x802f error:0x9762 NSERR_BDRSP_CARRY_ERR .

Procedure

From the above two points, you can confirm the operation scheme:

1, soft/hard reset GSCC main control to observe whether the solution, the field operation is invalid.

2, directly clear the OSN3500 network element database to download from the network management to solve the problem.

Root cause

The reason why the Huawei OSN3500 device SEP single board EUO8 interface board cannot be deleted is analyzed:

From the error codes and alarms, you can determine that the SEP single board checking subcard no longer exists, but the logical single board of the SEP single board subcard still exists at the host logical layer, which basically confirms that the host database abnormality is caused.

SEP single board OU08 interface board can not be added, the logical single board shows 09 C5 reason analysis:

From the alarms and abnormal display can determine the single board can be detected normally OU08 single board ID: 09 C5, but the host can not be added, while the display is abnormal, basically confirming that the host database anomaly caused.

Recommendations and Summary

It is recommended that in the case of the query to the logical single board is garbled, more consideration of the problem of the network element database.
