To verify hardware and software requirements are met

1. Review hardware and software requirements for SFCFSHA.

   See Assessing the system for installation readiness.

2. Verify the new system has the same identical operating system versions and patch levels as that of the existing cluster
3. Verify the existing cluster is an SFCFSHA cluster and that SFCFSHA is running on the cluster.
4. If the cluster is upgraded from the previous version, you must check the cluster protocol version to make sure it has the same version as the node to be added. If there is a protocol mismatch, the node is unable to join the existing cluster.

   Check the cluster protocal version using:

   # vxdctl protocolversion
   Cluster running at protocol 130

5. If the cluster protocol on the master node is below 130, upgrade it using:

   # vxdctl upgrade [version]

To set up the hardware

1. Connect the SFCFSHA private Ethernet controllers.

   Perform the following tasks as necessary:

   • When you add nodes to a cluster, use independent switches or hubs for the private network connections. You can only use crossover cables for a two-node cluster, so you might have to swap out the cable for a switch or hub.

   • If you already use independent hubs, connect the two Ethernet controllers on the new node to the independent hubs.

   Figure: Adding a node to a two-node cluster using two switches illustrates a new node being added to an existing two-node cluster using two independent hubs.

2. Make sure that you meet the following requirements:

   • The node must be connected to the same shared storage devices as the existing nodes.

   • The node must have private network connections to two independent switches for the cluster.

     For more information, see the Symantec Cluster Server Installation Guide.

   • The network interface names used for the private interconnects on the new node must be the same as that of the existing nodes in the cluster.

To prepare the new node

1. Navigate to the folder that contains the installsfcfsha program. Verify that the new node meets installation requirements.Verify that the new node meets installation requirements.

   # cd cdrom_root/storage_foundation_high_availability/

   # ./installsfcfsha -precheck 

   You can also use the web-based installer for the precheck.

2. Install SFCFSHA packages only without configuration on the new system. Make sure all the VRTS packages available on the existing nodes are also available on the new node.

   # ./installsfcfsha

   Do not configure SFCFSHA when prompted.
