internal I/O. The inactive iCAP CPU cannot be connected to an external I/O

Building Block Drawer.

2. GS1280: Neither CPU on the iCAP Dual CPU Building Block Module can be

connected to an external I/O Building Block Drawer.

You can enable one additional CPU at a time by using the DCL command

START/CPU. Format:

$ START/CPU [cpu-id]

If you do not specify a CPU ID in the command, the first inactive CPU that is

found (starting the search at CPU ID 0) will be started. On NUMA systems, it is

wise to select a specific CPU after considering the NUMA hardware

characteristics.

When a START/CPU command causes the number of active CPUs to exceed the

number of licenses you own for the system, this requires you pay for full use of

the CPU. You should contact Hewlett Packard to complete the purchase.

The following example shows the information that is displayed when a CPU is

activated.

$ START/CPU 4

%SYSTEM-I-CPUSELECTED, a selected CPU is attempting the

requested transition

$ SHOW CPU

ALPHA, an AlphaServer GS160 6/731

Multiprocessing is ENABLED. Streamlined synchronization image loaded.

Minimum multiprocessing revision levels: CPU = 1

PRIMARY CPU = 00

CPU sets:

Active 00 01 04

Configure 00 01 04 05

Potential 00 01 04 05

Autostart 00 01 04 05

Failover None

By comparing this display with the previous one, you can see that CPU 04 is

now active. Within 15 minutes the SYSTEM account will receive a mail

message notification of an iCAP event, which tells what action to take.

The following example shows a partial display of a iCAP event mail message:
