Description
Choose to enable or temporarily disable
the disaster recover feature. Choose Yes
(default) to enable disaster recovery.
Choose No to set the disaster recovery into
maintenance mode. It will automatically
set the Disaster Recovery back to Yes after
five minutes. This prevents the user from
accidentally disabling disaster recovery
permanently. To disable disaster recovery,
remove all the disaster recovery
configurations (Backup Channel and
Backup Transport settings).
The maintenance mode allows you to
perform any maintenance operations (such
as IP setup), without the unit declaring
disaster and initiating a disaster recovery
search path.
Note: Although the default is set to Yes,
the disaster recovery is not operational
until the search path is configured.
Parameters
Yes or No
