You can disable high availability (stateful SRP switchover) by launching Redundancy
Configuration mode and issuing the mode file-system-synchronization command or
specifying the no mode command.
In the file-system-synchronization mode, the router synchronizes the files and data such
as configuration files and releases that are stored in NVS (nonvolatile storage) between
the primary and standby SRP modules. This is the default behavior mode for E Series
routers that contain redundant SRPs.
Because this mode uses file synchronization instead of transaction-based mirroring,
when the active SRP module switches to the standby SRP, the router cold-starts.

mode
The switch route processor (SRP) module can operate in one of the two redundancy
modes—file system synchronization and high availability. When you disable high
availability, the router uses file system synchronization mode which is the default behavior
mode for E Series routers that use redundant SRPs. The router synchronizes the contents
of the NVS (nonvolatile storage) in the primary and standby SRP modules.
To disable high availability support:
From Global Configuration mode, launch Redundancy Configuration mode.
1.
host1(config)#redundancy
In Redundancy Configuration mode, you can disable high availability by doing one of
2.
the following:
Specify file system synchronization mode as the redundancy mode.
host1(config-redundancy)#mode file-system-synchronization
Specify the no version to disable high availability.
host1(config-redundancy)#no mode
