NetApp snapmirror resource not getting online with VCS integration

Dear All,

I would like to have some help to identify following error while onlining a NetApp SnapMirror agent that was intergrated with VCS.

The filer name and its credential s were given properly and even i can able to ssh it from the servers but for some reason the resource is not getting online and shows following error in the engine.log

2014/09/30 15:02:44 VCS WARNING V-16-20059-1002 (node)NetAppSnapMirror:testSM:online:Encountered errors while decrypting password!
2014/09/30 15:02:44 VCS ERROR V-16-20059-1000 (node11) NetAppSnapMirror:testSM:online:ONTAPI 'system-get-version' failed on filer node1.sys  Error : in Zapi::invoke, cannot connect to socket

Actually i am doing global Clustering configuration where i have two node cluster and a filer at primary site, In dr i have a single node cluster and a filer. the replication is async.

Any support highly appreacited.

Thanks.

Uvi.

 

  • uvahpux:

    Check the netappsnapmirror agent log.

     

    Normally, on graceful switch, after the application is shutdown and volumes unmounted, the snapmirror agent reverses the roles of the snapmirror pair.   From the netapp console, you will see the status as "snapmirror" but the source/destination will be reversed.

    If, however, the filers are not talking to each other properly, then the remote site will assume that the primarly is down, so, it forcefully breaks the relationship.  We call this "take over".    If you were to failback, then you would not see any updates at the primary.

    Check the status from netapp console.  Most likely you will see the status as "broken" for that pair.   To fix, right-click on the pair and perform a resync.  Make sure you select the correct direction :)

     

    I am working with another customer who is having a similar issue.   You mention that NetApp support fixed a communications problem.  Can you give some details on what they found and what they did to fix it?

     

    I will update this post if I fix my own problem.

     

    Cheers

  • Hi Clifford,

    The snapmirror configuration file at DR filer is similar to following ( fas1:vol1 fas2:vol2 ) so in this case the replication is working properly after the resync from console.  However after the switch over to DR site the snapmirror resource did not come and but onlineing the service group from DR site is working. So i am assuming that the replications is not happening from DR to Primary and i need to put some entrty similiar to following to Primary filer snapmirror.conf ( fas2:vol2 fas1:vol1 ) in order to relplicate the changes being written at DR site.
