*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 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 performed 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.
