258 Logical Partitions on System i5
In the second scenario, the current system has three OS400 LPARs (P0, P1and P2) and
consists of the 825 system unit, a 5094 tower with a 5088, a 5074. The essential resources
for the Primary partition are located in the 825 system unit (includes load source, disk and
console IOAs). All of the resources for Secondary Partitions P1 are in the 5074 tower and all
of the resources for P2 are in the 5094. The 5088 contains some switchable resources and
other Primary partition resources. There is production work done in the Primary partition of
the 825 which requires this partition to be migrated to the 570. Figure 9-2 is a general
illustration of the current and proposed systems.
Figure 9-2 Second scenario 825 to 570 upgrade
Tips: There are new DVD features for 520 and 570. Previous DVD features do not
physically fit in the system unit slots. The 520 has two DVD slots, but only one can be used
for OS400. There is no longer a Console IOA placement requirement in the System i5
system unit with the exception of Ops and LAN Console. The system unit can only hold
one logical partition.
