Hi Charles,
Changing the image profile requires a deactivation and reactivation of
the LPAR, so if the LPAR isn't already defined to allow dynamic storage
reconfiguration, you will need one IPL to get to the new state where it
is. The manual for this is the PR/SM Planning Guide, which has a good
discussion of the basics.
As Dave says, if the profile already has the storage available, CF STOR
will work dynamically.
When storage was more expensive, we had some Reserved storage as well as
the Initial to allow for CF STOR(E=1) to move it from one test LPAR to
another (overnight). Now we just have a single much larger Initial
setting and avoid the movement of storage between LPARs (i.e. CF STOR
OFFLINE in the donor and ONLINE in the recipient), which was sometimes
delayed by tasks holding storage intended to be reallocated.
best regards,
Peter

No. Might have to add it to the image profile on the HMC, and if already
there, then a CONFIG command on the console.

Subject: Does adding real storage require an IPL?

Today is real storage day. Sorry for the elementary questions.
The folks that own the box as a whole have added memory to our LPAR. Do we need
to IPL to pick that up in z/OS, or is there a command or similar process? I
thought I heard at a SHARE presentation that it could be done dynamically, but
the box owners are telling us an IPL is required.
PR/SM, not VM, if that matters.
Thanks much!
