Hi MV,
welcome to communities.
Can you please post a screenshot of the exact error (to help you better)
if i understood..while connecting to SVM it is throwing an error - unable to list vservers?
i would check for the below things...
1.pinging the management lif ipaddress should pass.
2.Is the firewall ports enabled? (or firewall stopped)
3.is nslookup for the svm management lif ip pointing to SVM name.
thanks
SR
