No access to CIFS shares following SVM-DR or MetroCluster switchover due to missing services in lif service-policy
Applies to
- ONTAP 9.11.1
- SVM-DR
- MetroCluster
- CIFS
Issue
- After SVM-DR migration cutover, the CIFS shares may not be accessible
- The SVM is unable to connect to name services (DNS, Active Directory, LDAP)
Example:
::*> vserver services access-check authentication show-creds -node <node-name> -vserver <svm-name> -uid <uid> Vserver: <svm-name> (internal ID: <id>) Error: Get user credentials procedure failed .. unreachable [ 9] Failed to connect to 10.10.10.100 for DNS: Network is unreachable ** [ 9] FAILURE: Unable to contact DNS to discover domain ** controllers. [ 9] Unable to make a connection (LDAP (NIS & Name Mapping):), Result: RESULT_ERROR_DNS_CANT_REACH_SERVER
- DNS is required to discover the AD domain services.
dns checkreturnsNetwork is unreachable
Example:
::*> dns check -vserver svm1 -name-server x.x.x.x
Vserver: svm1
Name Server: x.x.x.x
Name Server Status: down
Status Details: Network is unreachable.
- The service-policy applied to the SVM's LIF does not have the necessary management client services added
Example:
nas-cm911::> network interface show -vserver svm1 -lif lif1 -fields services
vserver lif services
