While in the vPars environment or in vPars mode, the total number of CPUs assigned to the virtual partitions
cannot exceed the current Intended Active number. This is true regardless of whether the virtual partitions
are up or down. If you encounter this situation, you may need to increase the Intended Active using
icod_modify -a to activate and assign CPUs to your virtual partition.
While in standalone or nPars mode, if the total number of CPUs assigned to the virtual partitions exceeds the
current Intended Active number for the nPartition, iCAP allows this in the vPars database but will display a
warning. If you attempt to boot this vPars database without increasing the Intended Active number using
the iCAP commands, the iCAP software will disallow this and shut down any virtual partitions attempting to
boot. You must reboot to standalone (PA-RISC) or nPars mode (Integrity), fix the situation so that the total
number of assigned CPUs is less than or equal to the Intended Active number, and then reboot the Monitor.
When assigning to an alternate and inactive vPars database, vPars and iCAP will allow the assignments, but
as in the above situation, if you attempt to boot this vPars database without increasing the Intended Active
number using the iCAP commands, the iCAP software will not allow this and will shut down any virtual
partitions attempting to boot. You must reboot to standalone (PA-RISC) or nPars mode (Integrity), fix the
situation so that the total number of assigned CPUs is less than or equal to the Intended Active number, and
then reboot the Monitor.
