Chapter 8. Capacity upgrades 215
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, with one reserved zAAPs and two reserved CPs
remaining 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 has one reserved CP and one reserved
zAAP remaining for future upgrades.
