*1

Mid Plane. A board that is located between the front and rear (SVC or FRT, CM or IOM side) of the ETERNUS DX.

*2

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.

*3

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.

*4

Bootup and Utility Device.

*5

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

*6

Can be replaced for configurations with two CEs.

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

*7

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