Hi Sahana,
Yes, those loopback IPs caused the SVM DR snapmirror failure.
So I have questions about the dns hosts file, if you think it is irrevalent to this SVM DR topic, then I will either post to another topic or open a case with NetApp support.
1. The host files entries sometime are necessery at the Unix but How critical is the host file entries for the C-DOT vserver?
2. All our vservers host file contain this loopback IPs. Maybe during the 7-mode transition we added them to the host file but I am not sure about this. Anyway, if I delete the 127.0.0.1 IP from the host file, how this will affect the NFS access?
3. is there any workaround without update the host file entries?
Thanks,
Chi
