| Description | Indicates whether redundant units may communicate
synchronization messages with each other. If communication is
not permitted, this object is set to 'true'. If communication
is permitted, this object is set to 'false'.
If the value of this object is 'true', the redundant system is
considered to be in a maintenance mode of operation. If the
value of this object is 'false', the redundant system is
considered to be in a normal (non-maintenance) mode of
operation.
In maintenance mode (true), the active unit will not
communicate with the standby unit. The standby unit
progression will not occur. When maintenance mode is disabled
(false), the standby unit is reset to recover.
Maintenance mode (true) is useful for maintenance-type
operations. |
