Sun Microsystems CP3260 manual Configuring Payload OS NIU Driver for Multiplexing to Zones 2 and

Depending the blade server’s hardware configuration, the Sun Netra CP3260 blade server can be used as a diskless client with the Solaris OS installed on a boot server (see Section 3.3, “Installing as a Diskless Clients” on page 3-4. The OS can also be downloaded to a boot device like the Netra CP32x0 SAS Storage ARTM, Dual HD, or an optional Compact Flash.

3.2Configuring Payload OS NIU Driver for Multiplexing to Zones 2 and 3

The MUX configuration by system management software and payload driver configuration must be in sync for proper functioning of both 10Gbps Ethernet (nxge) interfaces. The payload driver relies on the driver configuration file (nxge.conf) to initialize interfaces to either Zone 2 (backplane) or Zone 3 (ARTM). The driver uses phy-typeproperty to configure each interface. On the Netra CP3260 blade server, the phy-typecan have the following values:

■phy-type=gsd(for interface to operate at 1Gbps with Zone 2 connectivity)

■phy-type=xgsd(for interface to operate at 10Gbps with Zone 2 connectivity)

■phy-type=xgf(for interface to operate at 10Gbps with Zone 3 connectivity)

For default installations, the nxge driver is in the /platform/sun4v/kernel/drv directory.

The following examples show how to configure zone/link speed in the nxge driver file for Zone 2 and Zone 3 connectivity when using the Solaris OS.

CODE EXAMPLE 3-1Zone 2 Connectivity (Both nxge Ports)

name = "SUNW,niusl" parent = "/niu@80" unit-address = "0" phy-type = "gsd";

name = "SUNW,niusl" parent = "/niu@80" unit-address = "1" phy-type = "xgsd";

Note – The phy-type=”gsd”sets the interface at 1Gbps and the phy-type= ”xgsd” sets the interface at 10Gbps.

CODE EXAMPLE 3-2Zone 3 Connectivity (Both nxge Ports)

name = "SUNW,niusl" parent = "/niu@80" unit-address = "0" phy-type = "xgf";

name = "SUNW,niusl" parent = "/niu@80" unit-address = "1" phy-type = "xgf";
