Maintenance/Expansion

Hot Swap/Hot Expansion

"Hot swap" allows components to be replaced, or allows the firmware to be updated while the system is running.
"Hot expansion" allows components to be added while the system is running.

Hot Swap/Hot Expansion (ETERNUS AF250 S2)

The table below shows whether hot swap or hot expansion for components of the ETERNUS AF250 S2 is possible.

¡: Allowed / ´: Not allowed (cold swap is possible) / —: Not applicable
*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.
