Hi
I have a couple of guests that I need to add memory to without recycling the
guests. What are the steps and commands to accomplish this?
Thanks,
Terry

It is not possible to change the memory allocated to a guest without
logging off and logging on again.

Terry,
Do you have STANDBY memory defined in the virtual machines?
There is a section, 26.2 Set up memory hotplugging in The Virtualization
Cookbook for IBM z/VM 6.3, RHEL 6.4, and SLES 11 SP3 on the Web at
http://www.redbooks.ibm.com/abstracts/sg248147.html
Hope it helps.

One way is to have standby memory defined.
For example, if you have user LINUX and want to have 512MB with the chance to
go up to 2G, then you add the 2G as max memory on the USER directory statement:
USER LINUX PASWD 512M 2048M G 64
Then add the following statement to the user directory to
Ok, thanks for the information. I will plan the memory on the guests
accordingly.

Thanks Mike. I will take a look. One question I assume that if you allocate the
Standby memory in the guest Directory that it won't count against the memory
footprint until some of that standby is used is that correct?

Terry,
Yes, I believe (but have never proven it).

Terry,
You are right. Standby memory will not be allocated until you put it online
on Linux. Here we use to have all machines with a couple GB of standby
memory (and a couple processors too), so we can change it quickly when
needed.
We have SLES11 here, and we can put memory online AND offline
My apologies for being wrong about this.

If you didn't plan for it in advance, you can't do it. See
I'm not sure what Terry means by won't count against the memory footprint.
Standby and reserved storage is included in the calculations to determine
whether a live guest relocation will put the target member at risk for running
out of page space. See the help files for messages HCP1811I and
