Command History
Usage Guidelines The issu abortversion command allows the user to stop the ISSU process at any time before the user
commits to completing the process by issuing the issu commitversion command. Before any action is
taken, a check is performed to ensure that both RPs are either in the run version (RV) or load version
(LV) state.
When the issu abortversion command is issued before the issu runversion command, the standby RP
is reset and reloaded. When the issu abortversion command is issued after the issu runversion
command, the network switches to the former Cisco IOS software version.
Examples In the following example, the issu abortversion command resets and reloads the standby RP:
Router# issu abortversion a stby-disk0:c10k2-p11-mz.2.20040830
