Sajjad Premier — Tue, 11 Jan 2011 09:24:51 GMT

Dear,

There are two vpars (Web1, MQ2) in npar3 in Cell5 of SD32. We have physically installed 8GB memory in Cell5.

Now, we want to add new 8GB memory in one vpar (Web1). Our vpar version is:

A.04.03.03 HP-UX Virtual Partitions

We need to know step by step procedure to add additional 8GB memory in vpar (Web1).

Thanks & Kind Regards,

For static memory do

# vparmodify -p vpar-name -a mem::value_to_add

e.g.

# vparmodify -p Web1 -a mem::8192

Dynamic Memory allocation is not possible
for A.04.03.03

you can add memory as suggested by Torsen !!

# vparmodify -p vpar-name -a mem::8096

Dear,

Thanks for your response.

I have checked the physicall installed memory (8GB) by running command
vparstatus -A and showing ILM available 7741.

Please advise how much memory we can add like all memory 7741 or something less.

Secondly, our OS version is HPUX 11.23. So, is there anything to shutdown. I mean shutdown vpar or not. Please advise.

Screen shot is attached for your reference.

Thanks & Kind Regards,

Shutdown the vPar, add as much memory as you have, start the vpar. After adding, check with vparstatus command.

What is MQ?

Shutdown web1, remove 2GB, start web1.

# vparmodify -p Web1 -d mem::2048

(from another running vPar)

Once you removed 2GB memory from Web1 and Web1 is running again, shutdown MQ and add the memory

Web1# vparmodify -p MQ -a mem::2048

This is your step-by-step procedure
