Cluster not responding to SSH or System Manager due to DNS server outage
Applies to
- Cloud Volumes ONTAP
- ONTAP 9
Issue
- When attempting to access a Cloud Volumes ONTAP cluster deployed in Microsoft Azure, the cluster management LIF (cluster_mgmt) is inaccessible via SSH or System Manager.
- CIFS shares are unavailable to all users.
- The affected SVM is configured with only one DNS server, which is not reachable due to internal maintenance, resulting in loss of network connectivity to management and CIFS LIFs.
