Use the DEACTIVATE DEFINEDCAPACITY
command to manually decrease the Defined Capacity for an LPAR.
You can identify the LPAR either by the name of the LPAR and the name
of the CPC on which the LPAR is active, or by the name of the z/OS
system and sysplex running in the LPAR. In the second case, the z/OS
system needs to be defined in the active domain configuration. In
every case the respective CPC has to be defined in the active domain
configuration.
Note:
The number that is supplied
as the MSU parameter is the total limit to which the Defined Capacity
should be decreased, not the number of MSU by which you want to decrease
the limit.
Before performing the activation,
the Provisioning Manager checks for the following conditions:
that the specified LPAR is uniquely identified,
that at the HMC Defined Capacity is turned on for the LPAR,
that the target limit is a decrease, meaning that the new Defined
Capacity is lower than the current Defined Capacity.
The name of the sysplex to
which the specified system belongs.
SYS=name
The name of the system for
which LPAR you want to decrease the Defined Capacity. The specified
system must be currently observed.
CPC=name
The name of the CPC on which
to find the specified LPAR.
LPAR=name
The name of an LPAR for
which you want to decrease the Defined Capacity.
MSU=limit
The new Defined Capacity for the specified LPAR. The limit is
specified in MSU. The new value must be lower than the current Defined
Capacity and Defined Capacity must be turned on for the LPAR at the
HMC. A value between 1 and 100000 MSU can be specified.
Example
To decrease the Defined Capacity for system SYS1 in sysplex PLEX2
to 500 MSU, issue the following command:
