DCI Policy Overwrite console command not changing MSU values

• Dynamic Capacity Intelligence

Issue/Introduction

Trying to use the Dynamic Capacity Intelligence (DCI) Policy Overwrite console command, to change MIN/MAX MSU values for ABCD LPAR on A123 CPC:

F CONTROLR,POLICY,O,A123,SYS,ABCD,98,100,10

The command is accepted, per DCI1220I message, by the DCI Controller region (CONTROLR is the jobname), but the MSU values are not changed (no DCI1131I messages in DCILOG):

20230626 030902  DCI1220I: POLICY ACTION REQUEST RECEIVED: O,A123,SYS,ABCD,98,100,10  
20230626 031005  DCI1350I: POLICY AND CAPACITY CHECK CYCLE STARTED                        

The same Overwrite command, when issued from the "Status" panel of the DCI ISPF interface:

o_   ..ABCD/ABCDLPAR/A123

works fine:

20230625 151648  DCI1131I: OVERWRITE REQUEST FROM USER xxxxxx FOR:           
20230625 151648  DCI1131I:  CPC=A123 TYP=SYS ID=ABCDLPAR                     
20230625 151648  DCI1131I:  MIN MSU: 98 MAX MSU: 100 UNTIL 25/06/23 15:25    

Environment

Release : 2.0

Product: Dynamic Capacity Intelligence (DCI)

Cause

ABCD is not the LPAR name but the SYS ID (SMF ID) of that LPAR. The LPAR name is ABCDLPAR.

Resolution

As the Policy Overwrite console command requires using the LPAR ID, the correct command is the following:

F CONTROLR,POLICY,O,A123,SYS,ABCDLPAR,98,100,10
