The following prompt appears:
Are you sure? [Yes|No]:
Confirm your desire to perform a system restart by entering yes.
The system, when restarted, enables session recovery and creates all mirrored "standby-mode" tasks, performs packet
processing card reservations, and other operations automatically.
Step 5
After the system has been restarted, you should verify the preparedness of the system to support this feature as described
in Viewing Session Recovery Status, on page 328
More advanced users may opt to simply insert the require session recovery command syntax into an existing configuration
file using a text editor or other means, and then applying the configuration file manually. Exercise caution when doing
this to ensure that this command is placed among the first few lines of any existing configuration file; it must appear
before the creation of any non-local context.
Disabling the Session Recovery Feature
To disable the session recovery feature on a system, enter the no require session recovery command from
the Global Configuration mode prompt.
If this command is issued on an in-service system, then the system must be restarted by issuing the reload
command.
Important
Viewing Session Recovery Status
To determine if the system is capable of performing session recovery, when enabled, enter the show session
recovery status verbose command from the Exec mode prompt.
