Information
This command can be used to provide a hitless or warm upgrade. A hitless upgrade means
that a software upgrade does not require a reboot of the line cards. A warm upgrade means
that a software upgrade requires a reset of the line cards and SFMs. A warm upgrade is
possible for major releases and lower, while a hitless upgrade can only support patch releases.
You load the software upgrade on one RPM and then issue this command with the
rpm
keyword to move the software to the other RPM. The system senses the condition and
provides a series of prompts appropriate to that context, as shown in the following example:
Example
FTOS#redundancy force-failover rpm
Peer RPM's SW version is different but HA compatible.
Failover can be done by warm or hitless upgrade.
All linecards will be reset during warm upgrade.
Specify hitless upgrade or warm upgrade [confirm hitless/warm]:hitless
Proceed with warm upgrade [confirm yes/no]:
