Memory: Assigning by Size (CLM)

Before assigning CLM, see the section on conﬁguring CLM: “Conﬁguring CLM for an nPartition” on page 310.

Once CLM is conﬁgured, you can assign an amount of CLM to a virtual partition,

The syntax to assign an amount of CLM is:

-a|d cell:

cell_ID

:mem::

size

where:

a is adding

d is deleting

cell_ID

is the cell number

size

is the quantity of memory in MBs

Example

• To add 1024 MB of memory from cell 6 (at least 1024 MB must already be conﬁgured as CLM) to the

existing partition keira2:

keira1# vparmodify -p keira2 -a cell:6:mem::1024

• 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 to keira2:

keira1# vparmodify -p keira2 -a cell:6:mem::1024 -a mem::1024

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.
