Intended Active Boundary

Using the iCAP software, the Intended Active number represents the number of licensed CPUs that could be

activated within an nPartition. To view the current Intended Active number, you can use the iCAP command

icod_stat. To change the Intended Active number, you can use the iCAP command icod_modify.

While in the vPars environment (PA) or vPars mode (Integrity), the total number of CPUs assigned to the

virtual partitions cannot exceed Intended Active. This is true regardless of whether the virtual partitions are

up or down. If you encounter this situation, you may need to increase Intended Active using icod_modify -a

to activate and assign CPUs to your nPartition.

While in standalone (PA) or nPars (Integrity) mode, when 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 displays a warning that the virtual partitions in the vPars database will not boot. If you attempt

to boot the vPars Monitor using this vPars database without increasing Intended Active 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) 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.
