We have snapmirror running over SM-Sql in our setup.While giving a manual update from a snapdrive, snapmirror transfer initiated and gets aborted after few mins. We have two volumes in a snapmirror relation,one gets completed (small size) an another volume(200GB size) is in idle with a lag of more time .I hope there won't be any problem in Connectivity side ,since it is starting and aborting after some times. Also, i have verified the Snapmirror and EMS logs it simply showing as transfer failed and aborted.What would be next troubleshoot step for this issue .

Snapmirror is on.

I'm assuming that this used to work correctly?
One thing that comes to mind is making sure that the destination volume is large enough. If over time, you grow the source volume manually or with AutoGrow, the destination volume does not automatically grow to match.
On destination volumes, I usually thin provision them and make them significantly larger than my source volumes.

Sometime ago I faced an issue with snapmirror between sites where my replication started and after sometime it stopped with restart checkpoint.
In my case, it was a problem with the connectivity between sites. They had a link with SDH technology. After change the link, for other technology than SDH, the snapmirror worked fine.
Here is my 2 cents.
NetApp - Enjoy it!

We have another volume in relationship was in between the same site but it is very smaller one(15 GB ) compared to this volume (200 GB). The smaller one was running smoothly without any issue.

Above the SDH link, our support guys found out a pattern of files which replicated through this link, the replication hangs.
The same pattern of files replicated to other link than SDH worked fine.

Currently the volume is in progress ,it's an 100MB pt-pt link it would be slow
We have done a compression,because we able to see there are more no of packet drops in the packet trace.
