Figure 8-13 Shared logical partitions and zAAP upgrade example
This two-book server configuration has nine CPs and seven spare PUs. The concurrent
hardware upgrade adds three zAAP processors, using three available spare PUs on the
installed books. There are two activated logical partitions, both running z/OS V1.6 or higher:
LP1 has eight shared (SHR) logical CPs, two reserved CPs and four reserved zAAPs
defined.
LP2 has two shared (SHR) logical CPs, one reserved CP and three reserved zAAPs
defined.
The z/OS logical partition LP1, which has four reserved zAAPs defined, can configure online
all of the three zAAP processors added, remaining with one reserved zAAPs and two
reserved CPs for future image upgrades.
The z/OS logical partition LP2, which has three reserved zAAPs defined, is configuring two
zAAPs online. After this logical partition upgrade, LP2 remains with one reserved CP and one
reserved zAAP for future upgrades.
Dedicated, shared partitions and IFL upgrade
Figure 8-14 on page 214 is an example of a nondisruptive upgrade, adding two Integrated
Facility for Linux (IFL) processors to a 2084-B16, software model 309 server.
