The updatenode command installs and updates the CSM software and files on the nodes of the cluster. The nodes on which the updatenode command is run must already have the operating system installed.
Before the updatenode command can be run, ensure that the following tasks have been completed on the management server:
Nodes can be in one of three Modes at any given time during installation. When a node has only been defined, but not actually added to the cluster, it is in PreManaged mode. After a node has been defined and added to the cluster with the updatenode command, its Mode is Managed.
The updatenode command is run on nodes that have already been defined to the system. When updatenode is run, each node that was just defined (whose Mode attribute is PreManaged) becomes a managed node of the cluster. Note that if the updatenode command is not successful, the node's Mode attribute remains PreManaged.
/var/log/csm/updatenode.log and /var/log/csm/install.log on each node, can be reviewed to verify that the node was installed successfully.
To install the premanaged nodes of your cluster, type:
updatenode -P
By default, updatenode installs CSM and distributes configuration files to the nodes. However, you can designate that CSM perform only a subset of the default tasks via command line options. If you want to do this, see the man page or the CSM for Linux: Administration Guide for more information.
