*1 : Mid Plane. This is a board that is located between the front (drive side) and rear (controller
(CM) or I/O module (IOM) side) of the ETERNUS DX.
*2: All of the host interfaces on the CM that will have maintenance or expansion 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: System volumes must be created if Unified License is installed.
*4: Depending on the changes in the firmware, this function may require I/Os to be temporarily
stopped.
*5: Operation can be continued during a failure. The status of the ETERNUS DX can be monitored
via ETERNUS Web GUI or ETERNUS CLI.
*6: Hot expansion can only be performed when it is expanded together with a CM in a single-con-
troller configuration.
*7 : FEMs are installed in high-density drive enclosures.
