In addition to the above title, on our management servers (x2 Win 2012 R2 - SCOM 2012 R2), I am seeing the event ID 31551 stating:
Failed to store data in the Data Warehouse. The operation will be retired. Exception 'SqlException':Login failed for user 'xx'.
One or more workflows were affected by this.
Workflow name: Microsoft.SystemCenter.DataWarehouse.CollectEntityHealthStateChange
Instance name: management server
Instance ID: {xxxxxxxxxxxxxxxxx}
Management Group: XXXX
I've logged onto Data Warehouse server using the account referenced in the error message, loaded SQL Management Studio (2012 Std), and logged in and am able to see, view tables within the OperationsManagerDW database. So I'm trying to establish what's going on! If I can access the DW DB using the account, why am I getting these errors?
