Multiple Dedicated PR/SM Partitions
Configurations in which all PR/SM partitions use dedicated CPs, where there is
more than one dedicated partition, also support concurrent CP upgrade. CPs are
added to the configuration, without disruption to any of the partitions, and can be
brought online to a dedicated partition without an interruption. In the following
example, all ICFs in the configuration are dedicated. The partition (ICF 1) is defined
for the ability to be upgraded dynamically. To prepare for this ability, simply define
ICF 1 as a 2-way dedicated partition with one initial and one reserved logical CP
(see Figure 3-20 on page 3-63 for a similar example). At the time of the concurrent
CP upgrade, the CF operator command can be used in the ICF 1 dedicated
partition to configure a second ICF CP online to the dedicated partition without
interruption to any logical partition. Note the same type of procedure can be
accomplished with logical partitions using dedicated general purpose CPs.
Shared Internal Coupling Facility
Concurrent upgrade can be used to add a PU to a shared pool of PUs supporting
existing Internal Coupling Facilities. In the following example, Partition 1 is defined
for the ability to be upgraded dynamically. To prepare for this ability, simply define
Partition 1 as a 7-way shared partition with six initial and one reserved logical CPs
(see Figure 3-20 on page 3-63 for a similar example). At the time of the concurrent
CP upgrade, the CF operator command can be used in Partition 1 shared partition
to configure a seventh ICF CP online to the shared partition without interruption to
any logical partition. Note that Partition 2 in this case could have also been defined
as a 7-way shared ICF partition with one ICF configured offline. This would allow
Partition 2 to grow concurrently without an outage as well.
