Table 7–5 SRM Environment Variables for Soft Partitions

Environment Variable

lp_count n

lp_io_mask* x

lp_cpu_mask* x

lp_mem_size* n

lp_shared_mem_size n

lp_error_target

Definition

The number of soft partitions to create. Possible values are:

0Default. All IOPs, CPUs, and memory are assigned to one soft partition. No shared memory is defined.

1One 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.

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.

For the *, supply the partition number. The value x gives a binary mask indicating which CPUs are part of the partition.

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.

Size of memory shared by all partitions or a list of sizes on an 8 MB boundary.

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.
