Memory: Assigning (Adding) Or Deleting by Size (CLM)

Before assigning CLM, see the section on configuring CLM: “Configuring CLM for an nPartition”. Once CLM is configured, you can assign an amount of CLM to a virtual partition.

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 vPars Monitor when the virtual partition boots. The vPars 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 vPars Monitor, firmware, or bad pages, the sum of the ranges picked by the vPars 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. See also “Memory: Notes on vPars Syntax, Rules, and Output” and “Memory, CPU: Canceling Pending Operations”.
