HP-UX Virtual Partitions 6.0 Release Notes

IMPORTANT: If the system is brought down due to a faulty CPU core and the cores are
deconfigured, the vPars might not boot during the subsequent boot of the VSP. This is possible if
the sum of the remaining cores is less than the sum of the cores allocated to the VSP and vPars as
displayed from the vparhwmgmt command. You can clear this condition by removing the cores
from the vPars or VSP to meet the configuration requirements.
