The following is an example of a configuration for an Oracle VM environment in the case of using the NIC switching mode in Solaris 11 environment.
In the system below, virtual switches "primary-vsw0" and "primary-vsw1" are configured by using physical NICs "net0" and "net1" on the control domain. Virtual network devices "vnet0" and "vnet1" generated on the virtual switches are used on the guest domains.
The configuration of the control domain is any one of (1) or (2) below.
(1) GLS multiplexes the physical NICs (net0 and net1) to configure the virtual interface sha0
(2) GLS multiplexes the virtual network devices (vnet0 and vnet1) to configure the virtual interface sha0
Solaris 11.2 or later
The configuration (1) is recommended. However, both configurations (1) and (2) are available.
Solaris 11.1 or earlier
Only the configuration (2) is available.
On the guest domains, GLS multiplexes the virtual network devices (vnet0 and vnet1) to configure the virtual interface sha0.
In this configuration, the applications for each domain will perform data transmission using NIC multiplexed with the NIC switching mode. If an error occurs in the transfer path for NIC multiplexed with the NIC switching mode, since the IP address being used with each domain will be taken over from the active interface (net0, vnet0) to the standby interface (net1, vnet1), the applications on each domain will be able to continue transmission.
Figure D.1 Example when GLS multiplexes the physical NICs (net0 and net1) to configure the virtual interface sha0
Figure D.2 Example when GLS multiplexes the virtual network devices (vnet0 and vnet1) to configure the virtual interface sha0
Note
In Solaris 11.2 SRU15031 or later (Oracle VM 3.2 or later) environment, the configuration to set the virtual switches as the network devices is no longer supported. As a result, the configuration to multiplex the virtual switches cannot be used in GLS. To multiplex the virtual switches, configure the virtual network devices on the virtual switches to multiplex the virtual network devices as shown in "Figure D.2 Example when GLS multiplexes the virtual network devices (vnet0 and vnet1) to configure the virtual interface sha0."
Information
When multiplexing the virtual networks (vnet) with the NIC switching mode in Oracle VM environments, specify 0:0:0:0:0:0 to the MAC address of the standby patrol. Therefore, the virtual MAC address generated by Oracle VM with the standby patrol function will be used.
To configure the cluster system environment of Redundant Line Control function in Oracle VM environments, see "Using PRIMECLUSTER in Oracle VM Server for SPARC Environments" in "PRIMECLUSTER Installation and Administration Guide."
For the HUB monitoring destination, set up items such as the switches outside of the domain. If one has set those within the domain for monitoring, even if there is a malfunction with the physical interface comprising the virtual switches, the malfunction may not be detectable.
