Table 7–5 SRM Environment Variables for Soft Partitions
Environment Variable Definition
The number of soft partitions to create. Possible
values are:
0
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.
