CAUTION Not allowing enough memory for the other partitions will cause the other partitions to not boot.
You can boot the partition by freeing up enough memory for the partition to boot, such as by
shutting down an active partition.
If there are no memory ranges available to the partition below 2 GB, the partition will not boot.
If you use the defaults of the dynamic tunables, you will not run into the 2 GB limit. However, if you have
adjusted the dynamic tunables, it is possible to run beyond the 2 GB boundary. For more information on
adjusting the kernel size with dynamic tunables, see the white paper Dynamically Tunable Kernel
Parameters at http://docs.hp.com.
