HP Instant Capacity (iCAP) manual 134

Table 8-2 Use Case 1 — Configuration of Complex After Core Migration

Partition	Total Cores	Total Active Cores
nPar3	16	10
nPar4	8	4

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 8-3contains initial configuration of Complex1.

Table 8-3 Use Case 2 — Initial Configuration

Partition	Total Cores	Total Active Cores
nPar1	16	12
nPar2	16	10

Table 8-4contains Initial configuration of Complex2.

Table 8-4 Use Case 2 — Initial Configuration

Partition	Total Cores	Total Active Cores
nPar3	16	10
nPar4	8	8

Core migration from complex2 to complex1 may be done as follows:

Choose a partition(s) in complex2 where you would like to reduce the active core count. In this use case, we have chosen nPar4.

In nPar4:

# icapmodify –d 3

5 cores are intended to be active and are currently active.

The usage rights obtained from complex2 can be distributed among the partition(s) of complex1. In this use case, we distribute it among nPar1 and nPar2.

In nPar1:

# icapmodify –a 2

14 cores are intended to be active and are currently active.

In nPar2:

# icapmodify –a 1

11 cores are intended to be active and are currently active.

Core migration between the complexes is complete.

IMPORTANT: To remain in compliance, you must perform the deactivation operation first.

nPar2	16	11
