No, until they need the memory, you can give it to other LPARs.
We haven't reconfigured the storage element offline in an active lpar for a
long time, but years ago we had a need once and it did not work, because
that was a CICS allocated storage and stopping it was the same as IPL.
Alternatively you can add memory concurrently before activating the new
LPARs.
I don't believe there are many fans of it here.
In fact, if you predict new LPARs active, you should also plan the resources: IFLs *and memory*. You cannot reassign existing memory unless you have too much of it. I have too much (purchase granularity), so I can afford to have inactive LPARs with some memory assigned.
Memory is quite cheap, especially when compared to CPU resources.
