request system software abort in-service-upgrade (ICU)



Use this command to terminate an in-band cluster upgrade (ICU).

This command must be issued from a router session other than the one on which you issued the request system in-service-upgrade command that launched the ICU. If an ICU is in progress, this command terminates it. If the node is being upgraded, this command will cancel the upgrade. This command is also helpful in recovering the node in case of a failed ICU.

We recommend that you use the command only when there is an issue with the ongoing session of ISSU. You may need to manually intervene to bring the system to sane state if after issuing the command the system does not recover from the terminate.


This command has no options.
