Enable Dynamic Fan Speed Control

Enable SMW automatic fan speed control and view a fan speed table.

Dynamic fan speed has not enabled at the system level or on a specified row within the system.

Edit the system-level (hss.ini) file or a row-level (hss_rN.ini) file in the /opt/tftpboot/ccrd directory to set the fan_auto_speed_enable variable to 1.

Setting fan speeds dynamically on systems with mixed blower types within the same row is not supported. On systems with both STD and HP blowers in separate rows, fan speed settings must be done via row-specific ini files.
```
fan_auto_speed_enable=1
```
If the system is running, reload the ini file or files.
```
crayadm@smw> xtccr load_ini
```
The cooling software on each blade will automatically generate fan speed tables based on the CPUs and/or GPUs that are on the blade. To view the current fan speed table run the following command on the SMW:
```
crayadm@smw> xtdaemonconfig --daemon ccrd|grep _table
c0-0c0s7: fan_auto_speed_table_cpu=-:92:2750|91:87:2600|86:82:2450|81:77:2300|76:72:2150|71:-:*2000
c0-0c0s7: fan_auto_speed_table_gpu=-:80:2750|79:75:2600|74:70:2450|69:65:2300|64:60:2150|59:-:*2000
```
The above fan speed tables were generated for both the CPUs and the GPUs on blade c0-0c0s7. Each set of values between the | symbol gives the temperature range in degrees C and the corresponding fan speed in RPM. For example, For CPUs, a fan speed of 2750 RPM is specified for component temperatures of 92°C and above, and a fan speed of 2600 RPM is specified for component temperatures between 91°C and 87°C.
