# lenovo-sa120-fanspeed-utility
|
|
|
|
This is currently in prototype status.
|
|
|
|
## Requirements
|
|
|
|
Requires Python and the `sg_ses` utility, provided by [the `sg3_utils` package](http://sg.danny.cz/sg/sg3_utils.html).
|
|
|
|
Debian-based systems might use:
|
|
|
|
# apt-get install sg3-utils
|
|
|
|
On RHEL/CentOS systems:
|
|
|
|
# yum install sg3_utils
|
|
|
|
FreeBSD systems via `pkg`:
|
|
|
|
# pkg install sysutils/sg3_utils
|
|
|
|
FreeNAS 9.10 includes `sg_ses` as part of the standard image.
|
|
|
|
Solaris/OmniOS/OpenIndiana/SmartOS based systems:
|
|
|
|
Native Solaris should have sg3_utils installed. If executing `sg_ses` doesn't exist, it's necessary to install it from source. Installing napp-it, for the ZFS GUI, also installed all the requisite development tools.
|
|
|
|
On OmniOS CE, the steps involved were:
|
|
|
|
* Download [the `sg3_utils` package](http://sg.danny.cz/sg/sg3_utils.html). Move to somewhere like `/root` and extract.
|
|
* Change into the directory, configure with `./configure --prefix=/root/sg3_utils`.
|
|
* `make` && `make install`
|
|
* Run the fan script and set the path in the environment `sg_sess_path=/root/sg3_utils/bin/sg_ses python fancontrol.py 2`
|
|
|

|
## Usage
|
|
|
|
Finds the ThinkServer Enclosure automatically. Works when the devices are either `/dev/sg*`, `/dev/ses*`, or `/dev/bsg/*`
|
|
|
|
Use `fancontrol.py` to set the fan speed:
|
|
|
|
# python fancontrol.py 1
|
|
Enclosure not found on /dev/sg8
|
|
Enclosure not found on /dev/sg7
|
|
Enclosure found on /dev/sg6
|
