Define and create your first xCAT cluster easily¶
The inventory templates for 2 kinds of typical xCAT cluster is shipped. You can create your first xCAT cluster easily by making several modifications on the template. The templates can be found under
/opt/xcat/share/xcat/inventory_templates on management node with
Currently, the inventory templates includes:
a flat baremetal cluster, including openbmc controlled PowerLE servers, IPMI controlled Power servers(commented out), X86_64 servers(commented out)
flat_kvm_cluster_template.yaml: a flat KVM based Virtual Machine cluster, including PowerKVM based VM nodes, KVM based X86_64 VM nodes(commented out)
The steps to create your first xCAT cluster is:
create a customized cluster inventory file “mycluster.yaml” based on
cp /opt/xcat/share/xcat/inventory_templates/flat_cluster_template.yaml /git/cluster/mycluster.yaml
custmize the cluster inventory file “mycluster.yaml” by modifying the attributs in the line under token
#CHANGEMEaccording to the setup of your phisical cluster. You can create new node definition by duplicating and modifying the node definition in the template.
import the cluster inventory file
xcat-inventory import -f /git/cluster/mycluster.yaml
Now you have your 1st xCAT cluster, you can start bring up the cluster by provision nodes.
