Usage guidelines
This command is available in standalone mode.
When the standby MPU starts up, this command disables the system to examine the standby MPU's
startup software images for version inconsistency with the active MPU's current software images. The
standby MPU can start up with a different software version than the active MPU.
Even though you can use this command for upgrading software, HP recommends the ISSU method for
software upgrade. The startup software version check function might fail to work because the software
versions of the MPUs are incompatible.
To avoid anomalies, do not disable startup software version check for the standby MPU unless for
software upgrade.
To make sure the standby MPU always runs the same software images as the active MPU, configure both
the version auto-update enable command and the undo version check ignore command.
Examples
