HP-UX Virtual Partitions Administrator's Guide (includes A.03.05 and A.04.05)

NOTE: Assigning ILM or CLM memory by size only reserves the amount of physical memory
the virtual partition gets. The exact physical ranges of memory the virtual partition gets is decided
by the Monitor when the virtual partition boots. The Monitor will attempt to pick the memory
ranges such that the sum of the ranges add up to the amount of ILM and CLM reserved for the
partition. However, due to memory fragmentation, which occurs due to memory already taken
by the Monitor, firmware, or bad pages, the sum of the ranges picked by the Monitor may be
slightly less than or more than the specified amount reserved for the partition.
