Issue

From ONTAP EMS:
[Cluster-01: OscHighPriThreadPool: objstore.host.unresolvable:error]: Object-store server host name "rootxxxxxxxxxx.blob.core.windows.net" cannot be resolved to an IP address on node

From Cloud Manager server.log:
Failed getting device data for Cluster01. com.netapp.oncloud.simplicator.client.common.SimplicatorBadRequestException: rootxxxxxxxxxx.blob.core.windows.net: Name or service not known

Cause

When Azure Private Link is enabled a Private IP address for the storage account is configured. This causes CVO to try to resolve the Private IP in the internal DNS instead of the Public IP address it was previously resolving. 

 

Solution

Add a custom DNS entry for the new Private IP. 

 

Additional Information

  • Cloud Manager automatically creates an entry to Azure DNS on admin vServer on deployment of Single Node or HA Azure CVO which resolves the storage account to object store.
  • Add below entry if user accidentally deletes and does not plan to use private DNS as above.


::*> vserver services dns create -vserver svm1 -domains 21uckumchndedbu1u3ln20tv4e.zx.internal.cloudapp.net-name-servers 168.63.129.16
