I am trying to copy from a 8040 cluster running 9.1P20 to a ONTAP select cluster running in Azure at 9.12.1 and having issues getting NDMP to talk across the 2 clusters. I have Vserver scoped NDMP enabled on both controllers and am getting the following message:
Ndmpcopy: Starting copy [ 0 ] ...
Ndmpcopy: Socket bind or connect for IP x.x.x.x failed
Ndmpcopy: Ensure that node management or cluster management or intercluster IP of family type inet is present on the source filer
Ndmpcopy: Issue 'ndmpd on' on the destination filer to enable NDMP request then retry the connection
Ndmpcopy: Done
and this is the command line:
ndmpcopy -sa ndmpuser:xxxxxxx -da ndmpuser:xxx datalif2:/srcsvmname/vol/vol1/ftp_p datalif2:/dstsvmname/ftp_p

NDMP is showing enabled on both clusters. I have debug enabled on the controllers and I am getting no detail. I have a feeling this is a network issue, but since i am running at the node level, I am not sure how to troubleshoot connectivity other than ping that does work.

Make sure that each Netapp can ping everyplace. Verify that the svm on the destination has NDMP as an allowed protocol. Make sure the service policy on the destination allows for NDMP

~~do you have a lif with the correct service-policy?~~ okay, TMAC was quicker 🙂

Also I think you have to use the "vserver ndmp generate-password -vserver <srcsvmname> -user ndmpuser" and use the password from this command...

yep worked with support and for some reason we could not get the vserver to talk, they said the config looked right, but when we used the cluster SVM and the cluster interconnect IP's, it worked. I did see a bug about vserver connectivity with 9.1. I know we should not be using 9.1 but that is why we are copying everything off... Thanks all.

Actually come to think of it, I thought NDMP is supposed to work on intercluster lifs. Not regular data lifs

I guess it depends on the service-policy of the LIF...

Pretty sure at least NDMP requires communication using intercluster lifs. Not fully sure about ndmpcopy

according to the vserver properties of NDMP, it said Intercluster or data lifs in that order, but it would not work over the data lifs?? I would agree I thought the same thing, but I think that may have only been the case for node scoped NDMP. I am setting up 2 clusters in my lab now, to play with this. Much easier to play with when I control the network / firewalls.
