snapmirror replication transfer failed to complete

Snapmirror failed to update while giving the error replication transfer failed to complete.

I have checked everything on both source and destination.It is s VSM relationship and space,hosts entry,ontap version,snapmirror.conf entry,host access are not the issues.

 

I am not able to telnet filer to filer on 10566 to check port status.

 

Any ideas?

 

Data ONTAP Release 8.1.2P4 7-Mode --------Destination

Hi @Santosh_Pandey

 

Can you please check snapmirror.allow file .. both snapmirror source and entries should be there on that file. Please ask your network team to check the ports between 10565-10569.

 

Also please paste the below commands output.

 

snapmirror status -l <destination volume name>

Transfer was going on previously.Don't know if ports are not open and why.

Anyway to do filer to filer telnet?

we are using snapmirror.access host option so no allow file configured.

Thanks in advance

Please look in to the logs using below command, we can trace the root cause for this snapmirror transfer failure.

Re: snapmirror replication transfer failed to complete

Did not find anything specific in logs.

Any other ideas?

Hi @Santosh_Pandey

 

Are they pingable to each other?....... Some times it might be the issue with WAN also. Please reachout to your network team.

Hi,

 

The destination filer was not reachable from the source .Added entry in the hosts file.

Still unable to do snapmirror update

This issue is only for some volumes but for other volumes snapmirror is working fine.

This is for the same filer.How can this be possible if ports are not open

Re: snapmirror replication transfer failed to complete

Hi @Santosh_Pandey

 

From your snapmirror destinations out put, i am seeing two same destinations for same volume. Please look at the below output.

This might be the problem. Some one tried to create a one more snapmirror relationship for the same source and destination. Please use the below command to check which is the actual transfer.

 

snapmirror destinations -s <volume name>
