==== IPMI ==== It is possible to control the power or connect a console to your nodes being managed by Warewulf by connecting to the BMC through the use of IPMI. We will discuss how to set this up below. IPMI Settings ============= The common settings for the IPMI interfaces on all nodes can be set on a Profile level. The only field that would need to be assigned to each individual node would be the IP address. The settings are only written to the IPMI interface if ``--ipmiwrite`` is set to `true`. The write process happens at every boot of the node through the script ``/warewulf/init.d/50-ipmi`` in the **system** overlay. If an individual node has different settings, you can set the IPMI settings for that specific node, overriding the default settings. Here is a table outlining the fields on a Profile and Node which is the same as the parameter that can be used when running ``wwctl profile set`` or ``wwctl node set``. +----------------------+---------+------+--------------------+---------------+ | Parameter | Profile | Node | Valid Values | Default Value | +======================+=========+======+====================+===============+ | ``--ipmiaddr`` | false | true | | | +----------------------+---------+------+--------------------+---------------+ | ``--ipminetmask`` | true | true | | | +----------------------+---------+------+--------------------+---------------+ | ``--ipmiport`` | true | true | | 623 | +----------------------+---------+------+--------------------+---------------+ | ``--ipmigateway`` | true | true | | | +----------------------+---------+------+--------------------+---------------+ | ``--ipmiuser`` | true | true | | | +----------------------+---------+------+--------------------+---------------+ | ``--ipmipass`` | true | true | | | +----------------------+---------+------+--------------------+---------------+ | ``--ipmiinterface`` | true | true | 'lan' or 'lanplus' | lan | +----------------------+---------+------+--------------------+---------------+ | ``--ipmiwrite`` | true | true | true or false | false | +----------------------+---------+------+--------------------+---------------+ | ``--ipmiescapechar`` | true | true | single character | ~ | +----------------------+---------+------+--------------------+---------------+ Reviewing Settings ================== There are multiple ways to review the IPMI settings. They can be reviewed from a Profile level, all the way down to a specific Node. Profile View ------------ .. code-block:: console # wwctl profile list -a PROFILE FIELD PROFILE VALUE ===================================================================================== default Id -- default default comment -- This profile is automatically included for each node default cluster -- -- default container -- sle-micro-5.3 default ipxe -- -- default runtime -- -- default wwinit -- -- default root -- -- default discoverable -- -- default init -- -- default asset -- -- default profile -- -- default default:type -- -- default default:onboot -- -- default default:netdev -- -- default default:hwaddr -- -- default default:ipaddr -- -- default default:ipaddr6 -- -- default default:netmask -- -- default default:gateway -- -- default default:mtu -- -- default default:primary -- -- Node View --------- .. code-block:: console # wwctl node list -a n001 NODE FIELD PROFILE VALUE ===================================================================================== n001 Id -- n001 n001 comment default This profile is automatically included for each node n001 cluster -- -- n001 container default sle-micro-5.3 n001 ipxe -- (default) n001 runtime -- (generic) n001 wwinit -- (wwinit) n001 root -- (initramfs) n001 discoverable -- -- n001 init -- (/sbin/init) n001 asset -- -- n001 kerneloverride -- tw n001 kernelargs -- (quiet crashkernel=no vga=791 net.naming-scheme=v238) n001 ipmiaddr -- -- n001 ipminetmask -- -- n001 ipmiport -- -- n001 ipmigateway -- -- n001 ipmiuser -- -- n001 ipmipass -- -- n001 ipmiinterface -- -- n001 ipmiwrite -- -- n001 ipmiescapechar -- -- n001 profile -- default n001 default:type -- (ethernet) n001 default:onboot -- -- n001 default:netdev -- eth0 n001 default:hwaddr -- 11:22:33:44:55:66 n001 default:ipaddr -- 10.0.2.1 n001 default:ipaddr6 -- -- n001 default:netmask -- 255.255.252.0 n001 default:gateway -- -- n001 default:mtu -- -- n001 default:primary -- true Review Only IPMI Settings ------------------------- The above views show you everything that is set on a Profile or Node level. That is a lot of detail. If you want to view key IPMI connecton details for a node or all nodes, you can do the following. .. code-block:: console # wwctl node list -i NODE NAME IPMI IPADDR IPMI PORT IPMI USERNAME IPMI INTERFACE ================================================================================================== n001 192.168.1.11 -- hwadmin -- n002 192.168.1.12 -- hwadmin -- n003 192.168.1.13 -- hwadmin -- n004 192.168.1.14 -- hwadmin -- Power Commands ============== The ``power`` command can be used to manage the current power state of your nodes through IPMI. ``wwctl power [command]`` where ``[command]`` is one of: cycle Turns the power off and then on off Turns the power off on Turns the power on reset Issues a reset soft Shutdown gracefully status Shows current power status Console ======= If your node is setup to use serial over lan (SOL), Warewulf can connect a console to the node. .. code-block:: console # wwctl node console n001
