Environment Variables that Create Logical Partitions 3-9
Two-partition-systems may have two or three I/O modules.
Figure 3–5 gives two examples of three-I/O-module, two-partition systems. The
first shows partition 0 with one I/O module in slot 8, and partition 1 with two
modules in slots 6 and 7. The console commands are:
create –nv lp_io_mask0 100
create –nv lp_io_mask1 c0
The bottom of Figure 3–5 shows a two-partition system with the I/O modules in
slots 8 and 6 assigned to partition 0, and the I/O module in slot 7 assigned to
partition 1. The console commands used to create such partitioning are:
create –nv lp_io_mask0 140
create –nv lp_io_mask1 80
