*1 : 

All of the host interfaces on the CM that will have maintenance performed go offline. When a multipath configuration is used, switch to the host paths of the CM that will not have maintenance performed to continue operation.
*2 : 

When hot expanded, each CM must be pulled out to expand. Therefore, all host interfaces on the CM to be expanded will temporarily go offline.
*3 : 

Bootup and Utility Device.
*4 : 

An I/O suspension may be required depending on the firmware changes.
*5 : 

Mid Plane. This is a board that is located between the front and rear (controller (CM) or I/O module (IOM) side) of the ETERNUS DX.
*6 : 

Operation can be continued during a failure. The status of the ETERNUS DX can be monitored via ETERNUS Web GUI or ETERNUS CLI.
