Installing and Managing HP-UX Virtual Partitions (includes A.04.01)

Monitor and Shell Commands
Modes: Switching between nPars and vPars Modes (Integrity only)

On an Integrity system which has vPars software installed but does not have the correct
firmware version installed, you will see the following behavior depending upon the mode of
operation:
If the current mode is nPars, booting vmunix works as expected. Booting vpmon exits
with an unsupported environment message.
If the current mode is changed to vPars using vparenv or vparconfig, the hpux loader
does not allow boot of either the vpmon or vmunix. In this case, you should use
vparconfig to change mode back to nPars and reboot the system. You should then
install the required firmware. See the HP-UX Virtual Partition Ordering and
Configuration Guide for information on the required firmware.
