The customer inform me that during some test in him Huawei platform trainaing center and when he make switsh of the GSCC board from working slot 17 to standby slot 18 in OptiX OSN 3500 he check the data base differance using the comand:
He have always error:
failed! cmd:0x300a error:0x9127 NE IS BUSY : HBU
failed! cmd:0x300a error:0x9127 NE IS BUSY : HBU message when we try to compare the data base
When we make switsh from the active to standby main control board in the NGSDH equipement we must wait the batch backup finish before dowing any operation, for this we must use the command the following command to query the active/standby system control data synchronization:
0: Indicates the communication between the active and standby boards are broken, which may be caused by abnormal communication, because the standby board is not in position, or the socket is not established in time.
1: Indicates the active and standby boards are handshaking, which is a temporary status and it cannot be queried through this command; if this status remains for a long time, the handshaking between them fails.
2: Indicates the batch backup is performed, if this status remains for a long time (5 minutes), the batch backup between the active and standby boards fails.
3: The batch backup between the active and standby boards is accomplished successfully. On this basis, the active/standby switchover can be performed.
asck the customer to run the following command to query the backup schedule:
He tel me that the result is:
Backup-Info : 0x00000002
The means that the batch backup is performed, I asck him to run the comand :hbu-get-backup-info; so many time and waitaing to get the result Backup-Info : 0x00000003 in this time the batch backup between the active and the standby GSCC is finish and in this time he can compare all of the database.
The batch backup is performed for this we can't compare all the data base because is in use during the backup.
