The hardware architecture of this node. Valid values: x86_64, ppc64, x86, ia64.
|
||||
|
||||
* groups:
|
||||
Usually, there are a set of nodes with some attributes in common, xCAT admin can define a node group containing these nodes, so that the management task can be issued against the group instead of individual nodes. A node can be a member of different groups, so the value of this attributes is a comma-delimited list of groups. At least one group is required to create a node. The new created group names should not be prefixed with "__" as this token has been preserved as the internal group name.
|
||||
|
||||
* mgt:
|
||||
The method to do general hardware management of the node. This attribute can be determined by the machine type of the node. Valid values: ipmi, blade, hmc, ivm, fsp, bpa, kvm, esx, rhevm.
