Chapter 8. Capacity upgrades 211
Draft Document for Review April 7, 2004 6:15 pm 6947ch08.fm
Partition LP1 has two reserved CPs defined and, if the operating system running on it has the
capability of configuring processors online, this partition can be nondisruptively upgraded to
nine CPs, as shown in this example.
Partition LP2 has no reserved CPs, so it cannot be nondisruptively upgraded. If any upgrade
for this partition is required, it will require deactivation to configure more CPs.
Dedicated and shared logical partitions upgrade
Figure 8-12 shows a 2084-B16, software model 309 server. This two-book server
configuration has nine CPs and seven spare PUs.
Figure 8-12 Dedicated and shared logical partitions upgrade example
This 2084-B16, software model 309 (with no ICFs or IFLs) can be concurrently upgraded to
the software model 316 via LIC-CC, with no model upgrade.
There are three activated logical partitions: LP1 has three dedicated (DED) logical CPs and
two reserved CPs defined, LP2 has six shared (SHR) logical CPs and two reserved CPs
defined, and LP3 also has six shared (SHR) logical CPs and two reserved CPS defined.
This example shows an upgrade to the 2084-B16, software model 311, by adding
concurrently two more CPs to the physical configuration. Two available spare PUs are used
by LIC-CC for this upgrade. The physical upgrade ends here.
