Usage Guidelines
You can use the issu abortversion command at any time to stop the ISSU process. To complete the
process enter the issu commitversion command. Before any action is taken, a check ensures that both
supervisor engines are either in the run version (RV) or load version (LV) state.
When the issu abortversion command is entered before the issu runversion command, the standby
supervisor engine is reset and reloaded with the old image. When the issu abortversion command is
entered after the issu runversion command, a change takes place and the new standby supervisor engine
is reset and reloaded with the old image.
Examples This example shows how you can reset and reload the standby supervisor engine:
