• Memory

-a mem::size[:base|

floating] speciﬁes that at least size MB of base or ﬂoating ILM must

be available in the monitor. If size is not an integral multiple of the ILM granularity, it is ﬁrst

rounded up to the next granule boundary before testing for availability. By deﬁnition, this

memory is of type ILM.

-a cell:cell_id:mem::size[

:base|floating] speciﬁes that at least size MB of base or ﬂoat-

ing memory on cell cell_id must be available in the monitor. If size is not an integral multiple of

the CLM granularity, it is ﬁrst rounded up to the next granule boundary before testing for availa-

bility. By deﬁnition, this memory is of type CLM.

-m mem::size[:base|

floating] speciﬁes that the total base or ﬂoating memory in the target

vPar be set to size MB. This operation may result in assignment or deletion of base or ﬂoating

memory. Deletion of base memory can be done only when the target vPar is Down. The

-m option

is internally mapped to either a

-a

or -d option. The difference in the current memory size and

the speciﬁed memory size is rounded up before the addition or deletion. This may sometimes

result in the new memory to be more than the speciﬁed value if

-m is internally mapped to -a or

less than the speciﬁed value if

-m is internally mapped to -d. Here are a few examples to illus-

trate the above.

Example 1:

Suppose the current memory value of the target vPar is 1024MB and the speciﬁed new memory

value using -m is 1000MB. Also assume that the ILM granule size is set to 256MB. Since the new

speciﬁed value is less than the current value, the operation will be determined to be a "deletion".

Current value - Speciﬁed value == Value to be deleted.

1024 - 1000 == 24.

24MB is not granule aligned; hence, round up 24MB to the next granule 256MB.

So the command deletes 256MB from the current value resulting in 768MB which is less than

what the user asked for.

Example 2:

Suppose the current memory value of the target vPar is 1024MB and the speciﬁed new memory

value using -m is 1025MB. Also assume that the ILM granule size is set to 256MB. Since the new

speciﬁed value is greater than the current value, the operation will be determined to be an "addi-

tion".

Speciﬁed value - Current value == Value to be added.

1025 - 1024 == 1.

1MB is not granule aligned; hence round up 1MB to the next granule 256MB.

So the command adds 256MB to the current value resulting in 1280MB which is more than what

the user asked for.

-m cell:cell_id:mem::size[:base|floating] speciﬁes that the total base or ﬂoating CLM

from cell cell_id in the target vPar be set to size MB. This operation may result in assignment or

deletion of base or ﬂoating CLM. Deletion of base memory can be done only when the target vPar

is Down. The -m option is internally mapped to either a -a or -d option. The difference in the

current memory size and the speciﬁed memory size is rounded up before the addition or deletion.

This may sometimes result in the new memory to be more than the speciﬁed value if -m is inter-

nally mapped to -a or less than the speciﬁed value if -m is internally mapped to -d. Refer to the

examples above.

5) Explicit address ranges are assigned to both the CLM and ILM memory types. When you use the

mem:::base:range[:base|floating]

option to specify an explicit memory range, that range must not only be available for assignment,

but must reside entirely within one memory type. In addition, if the target vPar is Down the total

amount of memory speciﬁed in explicit memory ranges must be less than or equal to the total

memory of that type assigned to the vPar using the

cell:cell_id:mem::size[:base|floating]
