Usage
Information
Enabling this command keeps the failed RPM in the failed state. If there are two RPMs in the system,
enabling this command prevents the failed RPM from becoming a working Standby RPM. If there is only
one RPM in the system, the failed RPM does not recover and affects the system.
redundancy force-failover
Force the secondary stack unit to become the primary stack unit. You can also use this command to upgrade the software on
one stack unit from the other when the other has been loaded with the upgraded software.
Syntax
redundancy force-failover stack-unit
