Issue

The creation of the Protection of the NSM MySQL database hosted on the VMDK disk of the SC host partially fails.

The SnapCenter Backup of NSM using SCW then fails.

The following errors show in the CreateProtection job log :
System.Data.Entity.Infrastructure.DbUpdateException: An error occurred while updating the entries. See the inner exception for details. ---> System.Data.Entity.Core.UpdateException: An error occurred while updating the entries. See the inner exception for details. --->

The  nsm backup job log reports the following errors in SCW_Job_Id.log and SMCore_JobId.log:
