1 0
2 4
[Available CPUs]: 5

[Available I/O devices (path)]: 0.8.1
2.0.8
2.0.9

[Available ILM (Base /Range)]: 0x3000000/80
(bytes) (MB) 0x48000000/896
0x36c8000000/37248
[Available ILM (MB)]: 38224

[Available CLM (CellID Base /Range)]:

It already tells you that you have 38GB free RAM.
Available ILM (MB)]: 38224

Hi Turgay,

Thanks for making me understand.
I need to increase memory by 8Gb. I need to give following command from another vpar.

#vparmodify -p abcd -a mem::8192

Can you please confirm the command

Shalom,

Command looks good if you are adding 8 gb of ram to vpar abcd

As Steven say your command is ok.

If you have hp-ux 11.31 you can also add floating RAM, that you can add/remove RAM without shutting down the OS:
vparmodify -p -p abcd -a mem::8192:float

Hi Renu,

Few examples for your reference to add the memory.

Syntax
The basic syntax for adding or decreasing ILM resources assigned to a virtual partition is
-[a|d] mem::size
where
a is adding
d is decreasing
size is the quantity of ILM in MBs
Examples
To create the virtual partition winona1 with 1024 MB of ILM:
winona1# vparcreate -p winona2 -a mem::1024

To add 1024 MB of ILM to an existing partition winona2:
winona1# vparmodify -p winona2 -a mem::1024

To decrease the amount of ILM assigned to partition winona2 by 1024 MB:
winona1# vparmodify -p winona2 -d mem::1024

If your on vPars A.5.x.x -- meaning HP-UX 11.31 then you should be able to dynamically add memory (no downtime). Turgay illustrated this in the syntax he posted.

If your on 11.11/11.23, then you need to have your target vPar shut down to add memory.
