1816 The EBS tag is changed by user while managed.
Explanation
This error can occur if an attempt is made to change the Elastic Block Store (EBS) IBM-SV-cluster-id tag. The IBM-SV-cluster-id tag indicates that the storage is already managed by the system.
User response
Use the Amazon Web Services (AWS) console to revert the changes that were made to the EBS tag. EBS tags are key-value pairs. The key of the EBS tag must be IBM-SV-cluster-id. The value of the EBS tag must be the bitwise AND of the clustered system ID and the 0xFFFFFFFFF00FFFFF mask.
