nodeset - set the boot state for a noderange


nodeset [noderange] [boot|stat|iscsiboot|offline|runcmd=bmcsetup|osimage[=<imagename>]|shell|shutdown]

nodeset noderange osimage=<imagename> [--noupdateinitrd] [--ignorekernelchk]

nodeset [-h|--help|-v|--version]


nodeset sets the next boot state for a single or range of nodes or groups. It tells xCAT what you want to happen the next time the nodes are booted up. See noderange(3). nodeset accomplishes this by changing the network boot files. Each xCAT node always boots from the network and downloads a boot file with instructions on what action to take next.

nodeset will manipulate the boot configuration files of yaboot and pxelinux.0.

Assume that /tftpboot is the root for tftpd (set in site(5)).

nodeset for pxe makes changes to /tftpboot/pxelinux.cfg/{node hex ip}

nodeset for yaboot makes changes to /tftpboot/etc/{node hex ip}

nodeset only sets the next boot state, but does not reboot.

nodeset is called by rinstall and winstall and is also called by the installation process remotely to set the boot state back to "boot".

A user can supply their own scripts to be run on the mn or on the service node (if a hierarchical cluster) for a node when the nodeset command is run. Such scripts are called prescripts. They should be copied to /install/prescripts dirctory. A table called prescripts is used to specify the scripts and their associated actions. The scripts to be run at the beginning of the nodeset command are stored in the 'begin' column of prescripts table. The scripts to be run at the end of the nodeset command are stored in the 'end' column of prescripts table. You can run 'tabdump prescripts -d' command for details. The following two environment variables will be passed to each script: NODES contains all the names of the nodes that need to run the script for and ACTION contains the current nodeset action. If #xCAT setting:MAX_INSTANCE=number is specified in the script, the script will get invoked for each node in parallel, but no more than number of instances will be invoked at at a time. If it is not specified, the script will be invoked once for all the nodes.



Instruct network boot loader to be skipped, generally meaning boot to hard disk


Cleanup the current pxe/tftp boot configuration files for the nodes requested


Prepare server for installing a node using the specified os image. The os image is defined in the osimage table and linuximage table. If the <imagename> is omitted, the os image name will be obtained from nodetype.provmethod for the node.


Skip the rebuilding of initrd when the 'netdrivers', 'drvierupdatesrc' or 'osupdatename' were set for injecting new drviers to initrd. But, the geninitrd command should be run to rebuild the initrd for new drivers injecting. This is used to improve the performance of nodeset command.


Skip the kernel version checking when injecting drivers from osimage.driverupdatesrc. That means all drivers from osimage.driverupdatesrc will be injected to initrd for the specific target kernel.


If you would like to run a task after deployment, you can define that task with this attribute.


Display the current boot loader config file description for the nodes requested


This instructs the node to boot to the xCAT nbfs environment and proceed to configure BMC for basic remote access. This causes the IP, netmask, gateway, username, and password to be programmed according to the configuration table.


This instructs tho node to boot to the xCAT genesis environment, and present a shell prompt on console. The node will also be able to be sshed into and have utilities such as wget, tftp, scp, nfs, and cifs. It will have storage drivers available for many common systems.


To make the node to get into power off status. This status only can be used after runcmd and runimage to power off the node after the performing of operations.

noderes table - xCAT node resources file. See noderes(5) for further details.

nodetype table - xCAT node installation type file. See nodetype(5) for fur- ther details. This is used to determine the node installation image type.

site table - xCAT main configuration file. See site(5) for further details. This is used to determine the location of the TFTP root directory and the TFTP xCAT subdirectory. /tftpboot and /tftpboot/xcat is the default.
