For example, run the following command: vi /etc/fstab Table 5-2 lists the options that must be selected to create a mount path. Table 5-2.

The internal private network ensures that the DX Storage Cluster traffic is protected from unauthorized access and that the external network is isolated from both the PXE boot server and cluster multicast traffic. The DX Cluster Services Node software automatically allocates the first half of the Ethernet ports detected on each NIC interface card to the external network and the second half of the Ethernet ports detected on each NIC interface card to the internal network. All NICs allocated to a network are bonded into a bond interface using mode 6 or balance alb bonding. For example, on a server with four LOM ports and a quad port NIC adapter, LOM ports 0-1 and NIC adapter ports 0-1 are allocated to the external network in a balance-alb bond interface and LOM ports 2-3 and NIC adapter ports 2-3 are allocated to the internal network in a balance-alb bond interface. NOTE: Network switch configuration is outside the scope of the DX Cluster Services Node software. Switches must be properly configured by a system administrator to ensure correct connectivity and bonding mode support. Administrators must not connect the configured internal network ports to the external network. Disaster Recovery 37
