. Click the Create Adapter button, and then input the value for Virtual LAN ID, as shown in Figure 4-19 (the value for Slot will be filled in automatically. The use of the default value is sufficient). Click the OK button when done. Figure 4-19 Virtual Ethernet Slot and Virtual LAN ID (PVID) value c. Perform the same steps on the VIO_Server2 profile. Note: The two adapters you are creating need to be on a PVID that is unique for both (for example, both adapters must have the same PVID, and the PVID must not be used by any other adapter on the machine). As Figure 4-17 on page 212 shows, we put them on VLAN 99. 2. Right-click the VIO_Server2 partition and create a virtual Ethernet adapter. The value for Virtual LAN ID must be the same as the primary SEA (in this example, 1) and the Access External Network check box must be checked. 214 <strong>Advanced</strong> <strong>POWER</strong> <strong>Virtualization</strong> on IBM System p5
The Trunk priority flag for this SEA adapter is set to 2. This is for making the SEA adapter on VIO_Server2 the backup adapter. Click OK when done. 3. For the adapters to be available on both Virtual I/O Servers, you need to log in using the padmin user ID and run the cfgdev command on each Virtual I/O Server, since they were added dynamically. Tip: The settings for the Virtual Devices on each Virtual I/O Server are: On VIO_Server1: ► SEA Virtual Ethernet properties: – Virtual LAN ID 1 – Trunk priority 1 – Access external network button checked ► Virtual Ethernet for control channel use: Virtual LAN ID 99 On VIO_Server2: ► SEA Virtual Ethernet properties: – PVID 1 – Trunk Priority 2 – Access external network button checked ► Virtual Ethernet for control channel use: Virtual LAN ID 99 4. Change the SEA adapter device on VIO_Server1 using the chdev command, as shown in Example 4-3. Example 4-3 Shared Ethernet Adapter on VIO_Server1 $chdev -dev ent4 -attr ha_mode=auto ctl_chan=ent3 ent4 changed Define the SEA adapter device on VIO_Server2 using the mkdev command, as shown in Example 4-4.
