Environment Variables that Create Logical Partitions 3-7
Two-Partition System (GS60E or GS140)
A two-partition system has more possibilities for CPU allocation. For GS140
systems, from two to five slots may be occupied by CPU modules in TLSB slots
0 – 4. For GS60E systems, two to three slots may be occupied by CPU modules
in TLSB slots 0 – 2. Again, the CPUs in slot 0 must be assigned to partition 0.
Other than that, there are no restrictions.
The top portion of Figure 3–3 shows an allocation for a GS60E system with
three CPU modules in slots 0, 1, and 2. The CPUs in slot 0 are included in par-
tition 0, and the CPUs in slots 1 and 2 are included in partition 1. The console
commands used to create the appropriate masks are:
P00>>> create –nv lp_cpu_mask0 3
P00>>> create –nv lp_cpu_mask1 3c
The bottom portion of Figure 3–3 shows an allocation for a GS140 system with
five CPU modules in slots 0, 1, 2, 3, and 4. The CPUs in slots 0, 1, and 3 are
included in partition 0, and the CPUs in slots 2 and 4 are included in partition
1. You would use the following console commands to create such an allocation:
P00>>> create –nv lp_cpu_mask0 cf
P00>>> create –nv lp_cpu_mask1 330
NOTE: Once the desired environment variables have been created with
create –nv, you can change their values with the set command.
