R211x-HP Flexfabric 11900 Fundamentals Command Reference

198
you can roll back the software configuration to a rollback point to cancel all software image
upgrade-related operations performed after the rollback point. You can also roll back the software
configuration to the original software configuration (the software configuration before you performed the
ISSU).
For an incremental upgrade, up to 50 rollback points are supported. After the limit is reached, the oldest
rollback points are deleted to make room for newly created rollback points.
For ISSU upgrades and reboot upgrades, the system does not record and maintain any rollback point,
and you can roll back the software configuration only to the original software configuration.
Patch images do not support rollback.
Examples
# Roll back the software configuration to rollback point 1.
