Resolution

Try to bring the objects back to the healthy state, If it is stale validate and delete the object with the help of the Broadcom Support. for more information see KB below

Additional Information

This is as per the design to keep all production data available during any maintenance activity hence the host cannot enter Maintenance Mode if all objects are not healthy.
