<!-- PREREQUISITES -->
|
|
## Prerequisites
|
|
### iDRAC version
|
|
|
|
This Docker container only works on Dell PowerEdge servers that support IPMI commands, i.e. < iDRAC 9 firmware 3.30.30.30.
|
|
|
|
### To access iDRAC over LAN (not needed in "local" mode) :
|
|
|
|
1. Log into your iDRAC web console
|
|
|
|
|
|
|
|
2. In the left side menu, expand "iDRAC settings", click "Network" then click "IPMI Settings" link at the top of the web page.
|
|
|
|
|
|
|
|
3. Check the "Enable IPMI over LAN" checkbox then click "Apply" button.
|
|
|
|
|
|
|
|
4. Test access to IPMI over LAN running the following commands :
|
|
```bash
|
|
apt -y install ipmitool
|
|
ipmitool -I lanplus \
|
|
-H <iDRAC IP address> \
|
|
-U <iDRAC username> \
|
|
-P <iDRAC password> \
|
|
sdr elist all
|
|
```

<!-- PARAMETERS -->
|
|
## Parameters
|
|
|
|
All parameters are optional as they have default values (including default iDRAC username and password).
|
|
|
|
- `IDRAC_HOST` parameter can be set to "local" or to your distant iDRAC's IP address. **Default** value is "local".
|
|
- `IDRAC_USERNAME` parameter is only necessary if you're adressing a distant iDRAC. **Default** value is "root".
|
|
- `IDRAC_PASSWORD` parameter is only necessary if you're adressing a distant iDRAC. **Default** value is "calvin".
|
|
- `FAN_SPEED` parameter can be set as a decimal (from 0 to 100%) or hexadecimaladecimal value (from 0x00 to 0x64) you want to set the fans to. **Default** value is 5(%).
|
|
- `CPU_TEMPERATURE_THRESHOLD` parameter is the T°junction (junction temperature) threshold beyond which the Dell fan mode defined in your BIOS will become active again (to protect the server hardware against overheat). **Default** value is 50(°C).
|
|
- `CHECK_INTERVAL` parameter is the time (in seconds) between each temperature check and potential profile change. **Default** value is 60(s).
|
|
- `DISABLE_THIRD_PARTY_PCIE_CARD_DELL_DEFAULT_COOLING_RESPONSE` parameter is a boolean that allows to disable third-party PCIe card Dell default cooling response. **Default** value is false.
|
|
- `KEEP_THIRD_PARTY_PCIE_CARD_COOLING_RESPONSE_STATE_ON_EXIT` parameter is a boolean that allows to keep the third-party PCIe card Dell default cooling response state upon exit. **Default** value is false, so that it resets the third-party PCIe card Dell default cooling response to Dell default.

|
<!-- TROUBLESHOOTING -->
|
|
## Troubleshooting
|
|
|
|
If your server frequently switches back to the default Dell fan mode:
|
|
1. Check `Tcase` (case temperature) of your CPU on Intel Ark website and then set `CPU_TEMPERATURE_THRESHOLD` to a slightly lower value. Example with my CPUs ([Intel Xeon E5-2630L v2](https://www.intel.com/content/www/us/en/products/sku/75791/intel-xeon-processor-e52630l-v2-15m-cache-2-40-ghz/specifications.html)) : Tcase = 63°C, I set `CPU_TEMPERATURE_THRESHOLD` to 60(°C).
|
|
2. If it's already good, adapt your `FAN_SPEED` value to increase the airflow and thus further decrease the temperature of your CPU(s)
|
|
3. If neither increasing the fan speed nor increasing the threshold solves your problem, then it may be time to replace your thermal paste
