Issue

  • After performing DR cutover, SVM is unable to connect to the DNS server
    • This might affect CIFS or NFS access

Example:

::*> dns check -vserver svm1 -name-server x.x.x.x

Vserver: svm1
Name Server: x.x.x.x

Status Details: Network is unreachable.

 

  • The service-policy applied to the SVM's LIF does not have the DNS management client services added
