DESCRIPTION¶
Resources and settings to use when installing nodes.
noderes Attributes:¶
node
The node name or group name.
servicenode
A comma separated list of node names (as known by the management node) that provides most services for this node. The first service node on the list that is accessible will be used. The 2nd node on the list is generally considered to be the backup service node for this node when running commands like snmove.
netboot
The type of network booting to use for this node. Valid values: pxe or xnba for x86* architecture, yaboot for POWER architecture, grub2-tftp and grub2-http for RHEL7 on Power and all the os deployment on Power LE. Notice: yaboot is not supported from rhels7 on Power,use grub2-tftp or grub2-http instead, the difference between the 2 is the file transfer protocol(i.e, http or tftp)
tftpserver
The TFTP server for this node (as known by this node). If not set, it defaults to networks.tftpserver.
tftpdir
The directory that roots this nodes contents from a tftp and related perspective. Used for NAS offload by using different mountpoints.
nfsserver
The NFS or HTTP server for this node (as known by this node).
monserver
The monitoring aggregation point for this node. The format is “x,y” where x is the ip address as known by the management node and y is the ip address as known by the node.
nfsdir
The path that should be mounted from the NFS server.
installnic
The network adapter on the node that will be used for OS deployment, the installnic can be set to the network adapter name or the mac address or the keyword “mac” which means that the network interface specified by the mac address in the mac table will be used. If not set, primarynic will be used. If primarynic is not set too, the keyword “mac” will be used as default.
primarynic
This attribute will be deprecated. All the used network interface will be determined by installnic. The network adapter on the node that will be used for xCAT management, the primarynic can be set to the network adapter name or the mac address or the keyword “mac” which means that the network interface specified by the mac address in the mac table will be used. Default is eth0.
discoverynics
If specified, force discovery to occur on specific network adapters only, regardless of detected connectivity. Syntax can be simply “eth2,eth3” to restrict discovery to whatever happens to come up as eth2 and eth3, or by driver name such as “bnx2:0,bnx2:1” to specify the first two adapters managed by the bnx2 driver
cmdinterface
Not currently used.
xcatmaster
The hostname of the xCAT service node (as known by this node). This acts as the default value for nfsserver and tftpserver, if they are not set. If xcatmaster is not set, the node will use whoever responds to its boot request as its master. For the directed bootp case for POWER, it will use the management node if xcatmaster is not set.
current_osimage
Not currently used. The name of the osimage data object that represents the OS image currently deployed on this node.
next_osimage
Not currently used. The name of the osimage data object that represents the OS image that will be installed on the node the next time it is deployed.
nimserver
Not used for now. The NIM server for this node (as known by this node).
routenames
A comma separated list of route names that refer to rows in the routes table. These are the routes that should be defined on this node when it is deployed.
nameservers
An optional node/group specific override for name server list. Most people want to stick to site or network defined nameserver configuration.
proxydhcp
To specify whether the node supports proxydhcp protocol. Valid values: yes or 1, no or 0. Default value is yes.
comments
Any user-written notes.
disable
Set to ‘yes’ or ‘1’ to comment out this row.
