iCAP Use Cases
Core migration between partitions in a complex
Active cores can be redistributed across any or all partitions of the complex if those partitions
contain inactive cores.
Consider a complex with 2 nPartitions, nPar1 and nPar2. Table 4 displays the Initial Configuration
of the complex:
Table 4 Use Case 1 — Initial Configuration
Total Active CoresTotal CoresPartition
1216nPar1
28nPar2
Core migration from nPar1 to nPar2 can be done as follows:
In nPar1:
# icapmodify –d 2
10 cores are intended to be active and are currently active.
In nPar2:
# icapmodify –a 2
4 cores are intended to be active and are currently active.
IMPORTANT: To remain in compliance, you must perform the deactivation operation first.
Core migration between the partitions is now complete.
Configuration of Complex after core migration:

1016nPar3
48nPar4
IMPORTANT: The total number of active cores in the complex must not change at the end of this
operation.
Core migration across complexes (GiCAP)
Consider two complexes, complex1 and complex2 each with 2 partitions. The partitions nPar1
and nPar2 are contained in complex1; nPar3 and nPar4 are contained in complex2.
Table 6 contains initial configuration of Complex1.
