processors in the specified nodes. To fine tune the configuration, you can stipulate the hex mask in each <affinity specification> and specify the processors for each device.

Checking the log for errors

If you enter a configuration that is not valid, the settings will be disabled and an error will be display in the system logs.

Example:

fio-config -p FIO_AFFINITY 5,g0,0xf;6,0xf

In this example, the affinity for device fct6 is set incorrectly, because there is no group or node number before the mask. The following errors appear in the system log:

2011-09-09T12:22:15.176086800Z - ERROR - FusionEventDriver - FIO_AFFINITY: Invalid group or node number

2011-09-09T12:22:15.176086800Z - ERROR - FusionEventDriver - Invalid FIO_AFFINITY parameter syntax at character 13: "5,g0,0xf;6,0x". Manual affinity settings are disabled!
