If you do not need service nodes in your cluster then simply skip this section.
x CAT uses AIX/NIM commands to support diskless and standalone NIM clients.
For more information about NIM, see the ) This document assumes that you have already installed and configured your x CAT AIX management node by following the process described in the AIX overview document. For large scale cluster environments x CAT provides support for using additional installation servers.
In an x CAT cluster these additional servers are referred to as .
You can set up one or more service nodes in an x CAT cluster.
The number you need will depend on many factors including the number of nodes in the cluster, the type of node deployment, the type of network etc.
The process for this is described in the documentation mentioned above.For an x CAT on AIX cluster there is a primary NIM master which is on the x CAT management node(MN).The service nodes(SN) are configured as additional NIM masters. The x CAT support automatically handles the NIM setup on the low level service nodes and the distribution of the NIM resources.The database tar files that are available on the x CAT web site may contain multiple versions of RPMs - one for each AIX operating system level.When you are copying required software to your lpp_source resource make sure you copy the rpm that coincides with your OS level.
AIX service nodes must be diskfull (NIM standalone) systems.
