Veritas Storage Foundation 5.1 SP1 Cluster File System Installation Guide (5900-1510, April 2011)

Adding a node to a cluster using the SFCFS installer
You can add a node using the –addnode option with the SFCFS installer.
The SFCFS installer performs the following tasks:
■ Verifies that the node and the existing cluster meet communication
requirements.
■ Verifies the products and packages installed on the new node.
■ Discovers the network interfaces on the new node and checks the interface
settings.
■ Creates the following files on the new node:
/etc/llttab
/etc/VRTSvcs/conf/sysname
■ Updates the following configuration files and copies them on the new node:
/etc/llthosts
/etc/gabtab
/etc/VRTSvcs/conf/config/main.cf
■ Copies the following files from the existing cluster to the new node:
/etc/vxfenmode
/etc/vxfendg
/etc/vx/.uuids/clusuuid
■ Configures security on the new node if the existing cluster is a secure cluster.
Warning: If the root broker system has failed, then you must recover or
reconfigure the root broker system before you add a new node to the cluster.
■ Configures disk-based or server-based fencing depending on the fencing mode
in use on the existing cluster.
■ Adds the new node to the CVM, ClusterService, and VxSS service groups in
the VCS configuration.
Note: For other service groups configured under VCS, update the configuration
for the new node manually.
■ Starts SFCFS processes and configures CVM and CFS on the new node.
At the end of the process, the new node joins the SFCFS cluster.
