Table 3-5 shows all LPAR modes, required characterized PUs, operating systems, and the PU
characterizations that can be configured to an LPAR image. The available combinations of
dedicated (DED) and shared (SHR) processors are also shown. For all combinations, an
LPAR also can have reserved processors that are defined, allowing nondisruptive LPAR
upgrades.

Dynamically adding or deleting a logical partition name
Dynamically adding or deleting an LPAR name is the ability to add or delete LPARs and their
associated I/O resources to or from the configuration without a POR.
The extra channel subsystem and multiple image facility (MIF) image ID pairs (CSSID/MIFID)
can be later assigned to an LPAR for use (or later removed). This process can be done
through dynamic I/O commands by using HCD. At the same time, required channels must be
defined for the new LPAR.
Partition profile: Cryptographic coprocessors are not tied to partition numbers or MIF IDs.
They are set up with Adjunct Processor (AP) numbers and domain indexes. These are
assigned to a partition profile of a given name. The client assigns these AP numbers and
domains to the partitions and continues to have the responsibility to clear them out when
their profiles change.
Adding logical processors to a logical partition
Logical processors can be concurrently added to an LPAR by defining them as reserved in
the image profile and later configuring them online to the operating system by using the
appropriate console commands. Logical processors can also be concurrently added to a
logical partition dynamically by using the Support Element "Logical Processor Add" function
under the "CPC Operational Customization" task. This SE function allows the initial and
reserved processor values to be dynamically changed. The operating system must support
