Veritas Access Installation Guide

To assemble the cluster, do the following:

• Determine a preferred location for the cluster.

• Make sure that each node has at least two redundant Ethernet interfaces (gigabit Ethernet) to connect to a private network for cluster internal control.

• Make sure that each node has at least two additional Ethernet interfaces (gigabit Ethernet) to connect to the public network. You can use the public Ethernet interfaces from the embedded interfaces on the motherboard or from the add-on (PCI) network adapter interfaces.

• To connect the public NICs, connect one end of the Ethernet cables to the Ethernet interfaces on the back of the nodes. Connect the other end of the Ethernet cables to your corporate network so that they can reach the gateway. At least two public interfaces are required for each node.

• To connect the private NICs, use the first two available NICs when sorted by NIC name. Available NICs are those not connected to the public network or excluded from the node.

  For example, if your NICs are eth1, eth2, eth3, and eth4, and none of the NICs are connected to the public network or excluded, then use eth1 and eth2 as the private NICs.

  Connect one end of the Ethernet cables to Ethernet interface 1 and 2 on the back of the nodes. For a 2-node cluster, connect the other end of the Ethernet cables to the corresponding Ethernet interfaces on the second node. For a cluster with more than 2 nodes, connect the other end of the Ethernet cables to a dedicated switch or VLAN.

  Note:

  Veritas recommends to use InfiniBand NICs to configure LLT over RDMA for Veritas Access. Connect InfiniBand NICs as private or exclude the NICs when you install Veritas Access.

  See About using LLT over the RDMA network for Veritas Access.

  See Excluding a NIC.

• Ask your network administrator for the IP addresses to use in the Veritas Access installation. The number of IP addresses you need depends on the number of nodes and number of network interface cards in your cluster.

  You need at least one IP address per node per public interface. For virtual IP addresses, you can configure the virtual IP addresses later using the Veritas Access command-line interface if you input 0 for the number of virtual IP addresses per NIC during installation time.

  Veritas Access supports both Internet Protocol version 4 (IPv4) or Internet Protocol version 6 (IPv6), but they cannot be mixed.

  Physical IP address	An IP address that is associated with a specific Ethernet interface address and cannot automatically be failed over.
  Virtual IP address (VIP)	An IP address whose association to a specific Ethernet interface (VIP) can be failed over to other interfaces on other nodes by the Veritas Access software.
  Console IP address	A dedicated virtual IP address that is used to communicate with the Veritas Access cluster Management Console. This virtual IP address is assigned to the master node. If the master node fails, the Veritas Access software automatically selects a new master node from the cluster and fails the console IP address over to it.
