5. Locate the blinking adapter, replace it, and press Enter. The system will show the message Replace Operation Complete. 6. Select diagmenu, select Task Selection → Hot Plug Task → PCI Hot Plug Manager → Install/Configure Devices Added After IPL, and press Enter. This will call the cfgdev command internally and put all previously unconfigured devices back to Available. 7. If an FC adapter is replaced, the according measurements like zoning on the FC switch and definition of the WWPN of the replaced adapter to the storage subsystem have to be conducted before the replaced adapter can access the disks on the storage subsystem. For DS4000 storage subsystems, we recommend switching the LUN mappings back to their original controllers, as they may have been distributed to balance I/O load. 5.1.10 Changing TCP/IP configuration during production Starting with Virtual I/O Server Version 1.3, you know no longer need to remove TCP/IP configuration information with the rmtcpip command and add it back with the mktcpip command; the chtcpip command now controls configuration of the TCP/IP parameters on a system. Example 5-2 shows the syntax of the chtcpip command on the Virtual I/O Server. Example 5-2 Syntax of the chtcpip command $ chtcpip -help Usage: chtcpip [-interface Interface -inetaddr Address -netmask SubnetMask] chtcpip [-interface Interface -gateway -add New_Gateway_Address -remove OLD_Gateway_Address] -inetaddr -netmask -interface -gateway Change the IP address of the host. Specify the address in dotted decimal notation. SubnetMask Specifies the mask the gateway should use in determining the appropriate subnetwork for routing. Interface Specifies a particular network interface, for example: en0 Gateway Changes the gateway address for a static route. Specify the current address in dotted decimal notation and specify the new gateway address in dotted decimal notation. 278 <strong>Advanced</strong> <strong>POWER</strong> <strong>Virtualization</strong> on IBM System p5

The following windows will show you a new feature that comes with the HMC: ► Right-click the Virtual I/O Server partition where you want to see the topologies. Select Virtual I/O → Virtual SCSI adapter, as shown in Figure 5-18. Figure 5-18 Virtual I/O topology view selection Chapter 5. System management 279
