Before adding a node to a cluster
Before preparing to add the node to an existing SFCFSHA cluster, perform the required preparations.
Verify hardware and software requirements are met.
Set up the hardware.
Prepare the new node.
To verify hardware and software requirements are met
- Review hardware and software requirements for SFCFSHA.
- Verify the new system has the same identical operating system versions and patch levels as that of the existing cluster
- Verify the existing cluster is installed with Enterprise and that SFCFSHA is running on the cluster.
- 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 280
- If the cluster protocol on the master node is below 280, upgrade it using:
# vxdctl upgrade newProtocolVersion
Before you configure a new system on an existing cluster, you must physically add the system to the cluster as illustrated in Figure: Adding a node to a two-node cluster using two switches.
- 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.
- 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 Cluster Server Configuration and Upgrade 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.
Complete the following preparatory steps on the new node before you add it to an existing SFCFSHA cluster.
To prepare the new node
- Navigate to the folder that contains the installer program. Verify that the new node meets installation requirements.Verify that the new node meets installation requirements.
# ./installer -precheck
- Install Veritas InfoScale Enterprise filesets only without configuration on the new system. Make sure all the VRTS filesets available on the existing nodes are also available on the new node.
# ./installer
Do not configure SFCFSHA when prompted.
