issu abort

This is a command that an operator uses to manually stop the currently running upgrade.

The upgrade terminates after the current unit, the one that is going through the upgrade, rejoins the stack.

If a manual abort is done or ISSU detects an abort condition (with ISSU started with no on-error option), the stack is left as it is and a manual recovery is required. You must reload the primary or secondary image to bring the stack back to working condition after issuing the issu abort command.
