Dear Experts,

We have done HANA DB failover and failback. After the failback to primary host, the replication is not working. When we tried to register secondary, we are getting the below error.

Could you please let us know how to resolve this ?

Main Error:

Also,

I would suggest not using underscore in logical or physical hostnames. I see that in your command you have used name=PD1_secondary

Dear Siddhesh,

we were able to enable primary with name=PD1_primary. System replication was fine until the failover/failback with underscore before. If we change now the name, do we need to change any other settings accordingly ?

Thanks.

I am also assuming you stopped the secondary instance before trying to re-register it as secondary ?

Hi Siddhesh,

Yes, We have stopped secondary and tried to register but no luck.

Thanks,

Hello Pradeep,

Can you execute the command

hdbnsutil -sr_register --name=PD1_secondary --mode=sync --remoteHost=<primary_host> --remoteInstance=00 --force_full_replica

Replace the keywords as neccessary and post the output.

Regards,

Siddhesh

Hello Pradeep,

Also pay attention the parameter public_hostname_resolution in section  system_replication_hostname_resolution of global.ini

Dear Siddhesh,

Thanks for the link. It looks everything fine in the nameserver.ini file as well as host file. anything we need to check apart from this?

Thanks,

Pradeep

Hello Pradeep,

Not sure what seems to be the issue in the case. You may want to consider unregistering the secondary host/instance and re-registering it using hdblcm, but check documentation around it.

Regards,

Siddhesh
