Table 7–5 SRM Environment Variables for Soft Partitions

Environment Variable Definition

The number of soft partitions to create. Possible

values are:

Default. All IOPs, CPUs, and memory are

assigned to one soft partition. No shared

memory is defined.

lp_count n

1 One soft partition is created (partition 0).

You need to use the other environment

variables to define the partition.

2-8 From two to eight soft partitions can be

defined. You need to use the other

environment variables to define the

partitions.

lp_io_mask* x For the *, supply the partition number (0 – 7). The

value x gives a binary mask indicating which QBBs

(containing I/O risers) are included in the partition.

lp_cpu_mask* x

For the *, supply the partition number. The value x

gives a binary mask indicating which CPUs are

part of the partition.

lp_mem_size* n For the *, you supply the number of the partition.

The value n can be a size or list of sizes on a 64 MB

boundary.

lp_shared_mem_size n Size of memory shared by all partitions or a list of

sizes on an 8 MB boundary.

lp_error_target

The number of the soft partition that is to receive

error interrupts. The primary CPU of this soft

partition will receive the interrupts. If lp_count is

0, lp_error_target is ignored.
