Is it possible to freeze the operations of  any LPAR ?


I have 4 LPARs configured in my OS/390 system with production uncapped and
other capped sometimes when there is heavy CPU requirement for Prod LPAR I
have to bring down other 3 lpars so tht all MIPS will be used by Production
alone but bringing down other lpars is time consuming.

I wanted to Freeze the operations of other 3 LPARs using HMC so tht CPU will
be free for production usage and once production requirement is over I can
restored other LPAR operations.

Is it possible without changing dynamically MIPS allocations ?

You just wanted to dynamically change MIPS allocation. <g>
If you don't want these 3 LPARs to be available, just shut down the OSes and Deactivate the LPARs using HMC. If you want to lower their priority, the LPARs still have to be active, use Change LPAR Controls.
