This is really bugging me (it looks untidy 🙂 ) and is only affecting 2 relationships out of 15 we have so far altered.
We are migrating data from one aggr to another on the source, we have changed the snapmirror source on the destination filer but we can't get rid of the old snapmirror relationship from showing still on the source, as below..
Usually it is a snapshot or Conf file entry. You show no snaps. after removing the Conf file entry and snapmirror on it is still there? In that case it likely is a registry issue. I had one and support talks you through removing the entry. It sounds like that issue. It has a kb or Burt for it and a reboot to manually remove the registry entries
Have you done a snapmirror release (snapmirror release vol_esx03 PANNADR01:vol_esx03DR) on the source? I've found that, even though it generates errors saying the relationship doesn't exist or something similar, it does clean things up.
Yep I tried every snapmirror command under the sun, no difference. NetApp came back that it needed a registry hack and a reboot. They were going to escalate it to the next level and I am still waiting for them to come back to me 5 days later.
I had already offlined the luns and volumes but it would appear when I got around to destroying the volumes the relationships disappeared which is good.
