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 8-1 displays the Initial
Configuration of the complex:
Table 8-1 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.
