Transport Adapters

For the transport adapters, such as ports on network interfaces, specify the transport adapter names and transport type. If your configuration is a two-host cluster, you also specify whether your interconnect is a point-to-point connection (adapter to adapter) or uses a transport switch.

Consider the following guidelines and restrictions:

  • IPv6 – Oracle Solaris Cluster software does not support IPv6 communications over the private interconnects.

  • Local MAC address assignment – All private network adapters must use network interface cards (NICs) that support local MAC address assignment. Link-local IPv6 addresses, which are required on private-network adapters to support IPv6 public-network addresses for scalable data services, are derived from the local MAC addresses.

  • Tagged VLAN adapters – Oracle Solaris Cluster software supports tagged Virtual Local Area Networks (VLANs) to share an adapter between the private cluster interconnect and the public network. You must use the dladm create-vlan command to configure the adapter as a tagged VLAN adapter before you configure it with the cluster.

    To configure a tagged VLAN adapter for the cluster interconnect, specify the adapter by its VLAN virtual device name. This name is composed of the adapter name plus the VLAN instance number. The VLAN instance number is derived from the formula (1000*V)+N, where V is the VID number and N is the PPA.

    As an example, for VID 73 on adapter net2, the VLAN instance number would be calculated as (1000*73)+2. You would therefore specify the adapter name as net73002 to indicate that it is part of a shared virtual LAN.

    For information about configuring VLAN in a cluster, see Configuring VLANs as Private Interconnect Networks in Managing Hardware With Oracle Solaris Cluster 4.4. For information about creating and administering VLANs, see the dladm(8) man page and Chapter 4, Configuring Virtual Networks by Using Virtual Local Area Networks in Managing Network Datalinks in Oracle Solaris 11.4.

  • SPARC: Oracle VM Server for SPARC guest domains – For Oracle VM Server for SPARC guest domains that are configured as cluster nodes, specify adapter names by their virtual names, vnetN, such as vnet0 and vnet1. Virtual adapter names are recorded in the /etc/path_to_inst file.

  • Logical network interfaces – Logical network interfaces are reserved for use by Oracle Solaris Cluster software.
