You can add a node using the - addnode option with the product installer.
The product 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
Copies the following files on the new node:
/etc/llthosts
/etc/gabtab
/etc/VRTSvcs/conf/config/main.cf
Copies the following files on the new node:
/etc/llthosts
/etc/gabtab
/etc/VRTSvcs/conf/config/main.cf
/etc/vxfenmode
/etc/vxfendg
/etc/vx/.uuids/clusuuid
/etc/default/llt
/etc/default/gab
/etc/default/vxfen
/etc/vcsmmtab
Generates security credentials on the new node if the CPS server of existing cluster is secure
Configures disk-based or server-based fencing depending on the fencing mode in use on the existing cluster.
Configures disk-based fencing.
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. |
Note: |
Starts product processes and configures CVM and CFS on the new node.
Note: |
At the end of the process, the new node joins the existing cluster.
To add the node to an existing cluster using the installer
# cd /opt/VRTS/install
# ./installsfcfsha -addnode
The installer displays the copyright message and the location where it stores the temporary installation logs.
The installer uses the node information to identify the existing cluster.
Enter one node of the SFCFSHA cluster to which you would like to add one or more new nodes: galaxy
Enter the system names separated by spaces to add to the cluster: saturn
The installer checks the installed products and packages on the nodes and discovers the network interfaces.
Enter the NIC for the first private heartbeat link on saturn: [b,q,?] bge1
Enter the NIC for the second private heartbeat link on saturn: [b,q,?] bge2
The product installer verifies the network interface settings and displays the information.
Enter the NIC for VCS to use on saturn: bge3
When completed, the installer confirms the volumes are mounted indicates the location of the log file with details of the actions performed.
The installer then starts all the required Veritas processes and joins the new node to cluster.
