HP-UX Virtual Partitions Administrator Guide (includes A.05.08) (5900-1312, March 2011)

There are no minimum requirements of vPars for float memory assigned to a virtual
partition.
NOTE: Memory is bound to a virtual partition when the virtual partition is booted, when memory
is added online, and when assigned using an explicit user-specified range. Memory acquires the
base or float attribute only when it is bound to a virtual partition. The available memory ranges
within the vPars Monitor that are not bound to any virtual partition do not have any base or float
attribute.
Memory ranges assigned by the vPars Monitor, both ILM and CLM, cannot be deleted online. Only
user-assigned ranges of float memory can be deleted online.
The table below summarizes what you can do with each type of memory.

Syntax for Assigning (Adding) and Deleting Base and Float Memory
The resulting syntax to specify memory as either float or base is:
ILM/size: -a|d mem::size[:b[ase]|f[loat]]
CLM: -a|d cell:cell_ID:mem::size[:b[ase]|f[loat]]
Address: -a|d mem:::base:range[:b[ase]|f[loat]]
