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

The syntax to assign, delete, or modify an amount of CLM is:
-a|d|m cell:cell_ID:mem::size[:base|float]
where:
a
add
d
delete
m
modify
cell_ID
the cell number
size
the quantity of memory in MBs
base
add/delete as base memory
float
add/delete as float memory
Example
• To add 1024 MB of memory as float from cell 6 to the existing partition keira2:
keira1# vparmodify -p keira2 -a cell:6:mem::1024:float
• You can set both ILM and CLM memory on the same partition. To assign 1024 MB of available
CLM and 1024 MB of available ILM as base memory to keira2:
keira1# vparmodify -p keira2 -a cell:6:mem::1024 -a mem::1024
• To see how much of the ILM memory is currently float memory, use vparstatus -v as
shown in the example below.
# vparstatus -p winona4 -v

CLM, user-assigned [CellID Base /Range]: 0 0x700b0000000/256 (Floating)
(bytes) (MB) 0 0x700c0000000/256
CLM, monitor-assigned [CellID Base /Range]: 0 0x70080000000/512
(bytes) (MB) 0 0x700a0000000/256 (Floating)
CLM (CellID MB): 0 1280 (Floating 512)
CLM Granularity (MB): 256
NOTE: When assigning ILM or CLM memory to a down partition, the 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. If this occurs, the vPar Monitor adjusts the specified amount in the database to
the sum of the ranges that it picked.
