Task Type
|
|
=========
|
|
|
|
xCAT supports following types of task which could be set in the chain:
|
|
|
|
* runcmd ::
|
|
|
|
runcmd=<cmd>
|
|
|
|
Currently only the ``bmcsetup`` command is officially supplied by xCAT to run to configure the bmc of the compute node. You can find the ``bmcsetup`` in /opt/xcat/share/xcat/netboot/genesis/<arch>/fs/bin/. You also could create your command in this directory and adding it to be run by ``runcmd=<you cmd>``. ::
|
|
|
|
runcmd=bmcsetup
|
|
|
|
**Note**: the command ``mknb <arch>`` is needed before reboot the node.
|
|
|
|
* runimage ::
|
|
|
|
runimage=<URL>
|
|
|
|
**URL** is a string which can be run by ``wget`` to download the image from the URL. The example could be: ::
|
|
|
|
runimage=http://<IP of xCAT Management Node>/<dir>/image.tgz
|
|
|
|
The ``image.tgz`` **must** have the following properties:
|
|
* Created using the ``tar zcvf`` command
|
|
* The tarball must include a ``runme.sh`` script to initiate the execution of the runimage
|
|
|
|
To create your own image, reference :ref:`creating image for runimage <create_image_for_runimage>`.
|
|
|
|
**Tip**: You could try to run ``wget http://<IP of xCAT Management Node>/<dir>/image.tgz`` manually to make sure the path has been set correctly.
|
|
|
|
* osimage ::
|
|
|
|
osimage=<image name>
|
|
|
|
This task is used to specify the image that should be deployed onto the compute node.
|
|
|
|
* shell
|
|
|
|
Causes the genesis kernel to create a shell for the administrator to log in and execute commands.
|
|
|
|
* standby
|
|
|
|
Causes the genesis kernel to go into standby and wait for tasks from the chain. ...
