Detailed Instructions for lp_io_mask

The lp_io_mask environment variable is set to a hexadecimal mask in

which the bit position of a 1 indicates the slot in which the I/O module

resides.

A three-partition system requires three I/O modules (either one KFTIA plus two

KFTHA modules, or three KFTHA modules), one module for each partition.

Figure 3–4 shows the bit locations for assigning the I/O module in slot 8 to par-

tition 0, the I/O module in slot 7 to partition 1, and the I/O module in slot 6 to

partition 2. The console commands issued to create such partitioning are:

create –nv lp_io_mask0 100

create –nv lp_io_mask1 80

create –nv lp_io_mask2 40
