Install the memory and power up the 520 with partition standby; i.e. IPL the hardware but don't IPL the LPARs you want to change.
Update the LPAR profiles & activate/IPL the new profiles for the changes to take hold.

Subject: Memory upgrade on 520 with LPAR
I am adding some memory to a 520 (adding 8GB) and after Shannon's post
last week, I think the actual physical replacement of the existing 2GB
will be the easy part. What I want to do is add 6GB to the production
LPAR and 2GB to the Linux partition.
I know how to change the allocations using the HMC by going into the
partition profile but when do I do this? After I install the DIMM?
After the system IPL's? Seems to me that the HMC won't see the
additional 8GB until I power the 520 on and IPL. So do I IPL and then
change the partition profile?
Just need a pointer or two. Or, if you can point me in the right
direction in a manual somewhere I'd appreciate it. The System builder
has great diagrams, I just need to know the proper procedure to get the
HMC to see the new memory so I can allocate it to the partitions.
Thanks
