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 8-1displays the Initial Configuration of the complex:

Table 8-1 Use Case 1 — Initial Configuration

Partition	Total Cores	Total Active Cores
nPar1	16	12
nPar2	8	2

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:
