This command forces the backup unit to take over as the management unit and perform a warm restart of the stack. On a warm restart, the backup unit becomes the management unit without clearing its hardware tables (on a cold restart, hardware tables are cleared). Applications apply checkpointed data from the former management unit. The original management unit reboots.
If the system is not ready for a warm restart, for example because no backup unit has been elected or one or more members of the stack do not support nonstop forwarding, the command fails with a warning message.
The movemanagement command (see movemanagement) also transfers control from the current management unit; however, the hardware is cleared and all units reinitialize.
