Hi,
We just went to LPAR mode from basic mode. We have a 2066-002 (z800)
that is about 350 MIPS. We currently only have a single LPAR, but we
wish to CAP the LPAR at 200 MIPS. (for ISV charging purposes)
Is this easy to do? How? Can it be done without a POR or IPL?
Thanks for any help!
Yes, it is feasible, it is easy, it can be done dynamically.
Logon to HMC as SYSPROG, choose task list "CPC Operational
Customization". Then drag icon "Change LPAR Controls" and drop it on
your CPC icon. Then provide the numbers and check the "initial capping"
checkbox. Click "Save and Change".
Ooops! The only thing I forgot is you have *ONE* LPAR. Any number you
provide to the LPAR will give 100%... Well...
Maybe you have to add another LPAR. AFAIK it can be done dynamically,
but not on z/800.
BTW: Depending on your licence terms & conditions maybe it would be
better to use "soft capping" instead of "hard capping" described above.
In short, soft capping takes care about 4 hour rolling average, so
temporary peaks are allowed.
