configuring one more CP online, with one reserved CP for a future image upgrade. LP1 now
has four dedicated CPs, enabled by doing a nondisruptive upgrade.
From the eleven physical CPs available, seven CPs are left to be shared by LP2 and LP3
shared logical CPs.
LP2 has six logical CPs and two reserved CPs defined, but only one more can be
configured online, as the current configuration has only seven CPs to be shared. After the
LP2 logical upgrade, one reserved CP remains offline.
LP3 has the same configuration as LP2, and in this example, it is not being changed.
However, it could have one more reserved CP configured online.
LP1 and LP2 remain with one reserved CP each, but they cannot be configured online in
the current configuration. However, if LP1 configures one dedicated CP
offline , then LP2
can activate its last reserved CP.

Figure 8-13 is an example of a nondisruptive upgrade, adding three zSeries Application
Assist Processors (zAAPs) to a 2084-B16 software model 309 server.
