*1: Mid Plane. This is a board that is located between the front (drive side) and rear (controller (CM) side) of
the ETERNUS AF.
*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 per-
formed to continue operation.
*3: Depending on the changes in the firmware, this function may require I/Os to be temporarily stopped.
*4: Operation can be continued during a failure. The status of the ETERNUS AF can be monitored via ETERNUS
Web GUI or ETERNUS CLI.
