Power management of Bare Metal servers with Foreman
Power management of bare-metal servers is a new feature that comes with Foreman 1.2. You will need to have deployed Foreman and smart-proxy to 1.2 to enjoy this.
With that feature you will be able to provide a way to start, stop and reboot servers directly from Foreman’s Webinterface or from REST API.
This has been tested on DELL servers configuring DRAC/
Smart-proxy configuration
On your smart-proxy, you need:
* The rubyipmi gem installed
# gem install rubyipmi
* ipmitool installed:
# apt-get install ipmitool
Configuration in Foreman
You need to edit the host you want to manage with BMC:
- Go on foreman/hosts/server.example.com/edit
- Click on Network tab
- Click on ‘Add Interface’
- Type = ‘BMC’
- You need then to get the MAC address of your BMC interface. Connect to your server (server.example.com in my example) in ssh and then using ipmitool command :
# ipmitool lan print
Foreman will automaticaly add a DNS record and a DHCP lease for your interface.
However, there is a bug in 1.2.0 where Foreman doesn’t append correctly the domain to the name of the card (see the open bug ). As a woraround, you can set in Name field the FQDN of your interface name (ie: server-ipmi.example.com)
- Eventualy choose a user/password then save.
IPMI configuration
On the server, you still need to configure it to allow Foreman to use it :
You can use the following ipmitool commands :
# ipmitool lan set 1 ipsrc dhcp # ipmitool lan set 1 access on # ipmitool user set name 3 your_user # ipmitool user set password 3 your_password # ipmitool channel setaccess 1 3 callin=on ipmi=on link=on privilege=4 # ipmitool user enable 3
How to use that feature
On the host page, if all went well, you should be able to manage from Foreman the power of the server :
A new feature to integrate more deeply Foreman with all your servers. Foreman is getting better and better !
