7.7 Hard Partitioning

Hard partitioning allows you to run multiple operating systems on one

hardware system. Table 7–6 lists the SCM environment variables used

to create hard partitions. After entering the SCM commands, set the

control panel switch to Off and then to On to create the hard partitions.

Table 7–6 SCM Environment Variables for Hard Partitions

Environment Variable Definition

hp_count

A value from 0 to n indicating the number of hard

partitions to be configured. Partitions are numbered

from 0 to n–1. If this value equals 0 or 1, partitioning

is disabled and the system remains in standard SMP

mode.

hp_qbb_maskx

A bitmask of QBBs to be included in hard partition x.

In Example 7–7, a GS160 system is hard partitioned into 2 partitions with:

•

QBB 0 and QBB 1 in partition 0, and,

•

QBB 2 and QBB 3 in partition 1

Example 7–7 Defining Hard Partitions

SCM_E0> set hp_count 2

SCM_E0> set hp_qbb_mask0 3

SCM_E0> set hp_qbb_mask1 c
