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
|
|
`ipmitool`. Other methods can also configured, but require additional
|
|
configuration.
|
|
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 and are done with `ipmitool`.
|
|
|
|
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``.
|
|
|
|

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.

|
|
|

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
|
|
|
|
|
|
Ipmi template
|
|
=============
|
|
|
|
As warewulf doesn't manage the ipmi/bmc interfaces directly, but calls ``ipmitool``
|
|
this managed with a template which defines the behavior. For ``ipmitool`` following
|
|
template is used
|
|
|
|
.. code-block:: golang
|
|
{{/* used command to access the ipmi interface of the nodes */}}
|
|
{{- $escapechar := "~" }}
|
|
{{- $port := "623" }}
|
|
{{- $interface := "lan" }}
|
|
{{- $args := "" }}
|
|
{{- if .EscapeChar }} $escapechar = .EscapeChar {{ end }}
|
|
{{- if .Port }} {{ $port = .Port }} {{ end }}
|
|
{{- if .Interface }} {{ $interface = .Interface }} {{ end }}
|
|
{{- if eq .Cmd "PowerOn" }} {{ $args = "chassis power on" }} {{ end }}
|
|
{{- if eq .Cmd "PowerOff" }} {{ $args = "chassis power off" }} {{ end }}
|
|
{{- if eq .Cmd "PowerCycle" }} {{ $args = "chassis power cycle" }} {{ end }}
|
|
{{- if eq .Cmd "PowerReset" }} {{ $args = "chassis power reset" }} {{ end }}
|
|
{{- if eq .Cmd "PowerSoft" }} {{ $args = "chassis power soft" }} {{ end }}
|
|
{{- if eq .Cmd "PowerStatus" }} {{ $args = "chassis power status" }} {{ end }}
|
|
{{- if eq .Cmd "SDRList" }} {{ $args = "sdr list" }} {{ end }}
|
|
{{- if eq .Cmd "SensorList" }} {{ $args = "sensor list" }} {{ end }}
|
|
{{- if eq .Cmd "Console" }} {{ $args = "sol activate" }} {{ end }}
|
|
{{- $cmd := printf "ipmitool -I %s -H %s -p %s -U %s -P %s -e %s %s" $interface .Ipaddr $port .UserName .Password $escapechar $args }}
|
|
{{ $cmd }}
|
|
|
|
In order to use another template, its filename must be specified for a node or profile via the
|
|
``--ipmitemplate`` switch and the template must placed under ``/usr/lib/warewulf/bmc`` or to the
|
|
path which is was defined as ``datadir`` in ``warwulf.conf`` or during compile time.
|
|
All IPMI specific variables are accessible in the template which are the following
|
|
|
|
| Parameter | Template variable |
|
|
+=====================+====================+
|
|
| ``--ipmiaddr`` | ``.Ipaddr`` |
|
|
+---------------------+--------------------+
|
|
| ``--ipminetmask`` | ``.Netmask`` |
|
|
+---------------------+--------------------+
|
|
| ``--ipmiport`` | ``.Port`` |
|
|
+---------------------+--------------------+
|
|
| ``--ipmigateway`` | ``.Gateway`` |
|
|
+---------------------+--------------------+
|
|
| ``--ipmiuser`` | ``.UserName`` |
|
|
+---------------------+--------------------+
|
|
| ``--ipmipass`` | ``.Password`` |
|
|
+---------------------+--------------------+
|
|
| ``--ipmiinterface`` | ``.Interface`` |
|
|
+---------------------+--------------------+
|
|
| ``--ipmiwrite`` | ``.Write`` |
|
|
+---------------------+--------------------+
|
|
| ``--ipmiescapechar``| ``.EscapeChar`` |
|
|
+---------------------+--------------------+
|
|
| ``--ipmitemplate`` | ``.Template`` |
|
|
+---------------------+--------------------+
|
|
|
|
Additional the ``.Args`` variable is accessible which can have following
|
|
values:
|
|
* `PowerOn`
|
|
* `PowerOff`
|
|
* `PowerCycle`
|
|
* `PowerReset`
|
|
* `PowerSoft`
|
|
* `PowerStatus`
|
|
* `SDRList`
|
|
* `SensorList`
|
|
* `Console`
|
|
which are the calls done by `wwctl power` commands.
|
|
|
|
Also the script ``/warewulf/init.d/50-ipmi`` in the **system**
|
|
overlay may need an update. There the variables must have the prefix ``.Ipmi``
|
