841 Supported hardware change detected.

  Explanation
A change was detected in the node or node canister hardware configuration. The
    new configuration is supported by the node software or the node canister machine code. The new
    configuration does not become active until it is activated. 
A node or
    node canister configuration is remembered only while it is active in a system. This node or node
    canister error is therefore resolved by using the management GUI.

  User response
Use the management GUI to
    run the suggested actions for the associated service error code. Use the directed maintenance to
    accept or reject the new configuration.

   The following note does not apply to IBM Storage Virtualize for Public Cloud or FlashSystem 900.
