*1:
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.
*2:
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.
