This chapter describes how to use both sets of AXD tools. Before you can use AXD tools, make sure you've properly started up the tools. For more information, see Chapter 3, "Starting Up AXD Tools, " on page 17. Setting AXD to Host, Client, or Local Mode AXD tools can start up in any of three modes, depending on whether:  You're opening AXD EFI tools or AXD Mac OS X tools  Any of the computers on the same subnet are host computers  A host computer is directly connected  You're logged in as root  You're running AXD Mac OS X tools on a computer that isn't an Intel-based Xserve 23 The following table describes the three modes: Mode Host Description Automatically enters mode if You run AXD Mac OS X tools The computer searches for and either: Xserve computers that are on the same subnet and start AXD  The computer isn't an Inteltools in remote mode. When based Xserve one is found, the host computer  You're not logged in as root controls AXD tools on the client Xserve. The Xserve can be controlled by You're running AXD EFI tools a host computer. You're running AXD EFI tools and a host computer isn't on the same subnet and isn't directly connected. Client Local If you're logged in as root on an Intel-based Xserve, and then you run AXD Mac OS X tools, you can choose which mode to enter. Remotely Testing a Client Xserve If you want to test a client Xserve, you must first start up AXD tools on the host computer, set it to connect to a client Xserve, and then start up the AXD tools on the client Xserve and set it to be a client of a remote host. The available tests are based on which AXD tools the client Xserve is running. When you start up AXD EFI tools, the Xserve first looks for a host computer. If it doesn't find a host computer, the Xserve enters local mode. When you start up AXD Mac OS X tools, the Xserve automatically becomes a host computer if either of the following are true:  You logged in to Mac OS X with an account that isn't root.  You are running AXD Mac OS X tools on a computer that isn't an Intel-based Xserve. If AXD Mac OS X tools doesn't automatically become a host computer, it asks if it should connect to a client Xserve, be a client of a remote host, or run tests locally. To remotely test a client Xserve: 1 On the host computer, open AXD Mac OS X tools (located in /Applications/). 24 Chapter 4 Using AXD Tools 2 If the host computer is an Intel-based Xserve and you're logged in as root, when AXD Mac OS X tools opens, a dialog asks you to choose which mode to enter. If your computer isn't an Intel-based Xserve, the dialog doesn't appear, and AXD Mac OS X tools automatically enters host mode. 3 On the client Xserve, change the startup disk to a volume with AXD tools and restart it. You can also temporarily change the startup disk to either a volume with AXD tools on it or to an AXD tools NetBoot disk image when you start up the Xserve. For more information about how to change or temporarily change the startup volume, see Chapter 3, "Starting Up AXD Tools, " on page 17. 4 If you're starting up AXD Mac OS X tools, log in as root, and if AXD Mac OS X tools doesn't open automatically, open the AXD application (located in /Applications/). 5 If you're starting up AXD EFI tools, the Xserve automatically enters client mode. There are several ways to determine whether the host computer and client Xserve have established a successful connection:  The IP address field in the AXD window on the host computer should match the IP address assigned to the client Xserve.  The name of the AXD window on the host computer is "AXD remote log, " not "AXD local log. "  The log area of the client Xserve uses more of the AXD window. [. . . ] Also verifies that the mapped-in DIMM size is appropriate for the slot it's inserted into. Reports the number of ECC errors, and then resets the count. SMBIOS Self-Test 1 second ECC Error Count 1 second Appendix AXD Tools Test Reference 43 Ethernet Controller Tests The availability of Ethernet controller tests depends on the Enternet controller installed in the Xserve. Consider disconnecting from the network before running the data loop tests. Test MAC Address Verification Ethernet ROM Checksum MAC Loopback Estimated completion time 1 second 1 second 1 minute Description Verifies MAC address is not all FFs or 00s. Verifies that there's no data mismatch between sent and received data while looping within the MAC (a sublayer of the datalink layer in the ISO network reference model). PHY 1000 Loopback 20 seconds per port, 40 seconds Verifies that there's no data total mismatch between sent and received data while looping within the physical transport medium (PHY) at 1000 Mbps.
