Installing SunSwift SBus Adapter Software On Solaris 2.4 and 2.5 Systems 3 This chapter describes SunSwift SBus Adapter software installation requirements for Solaris 2.4 and 2.5 software versions only. Note – You must have already installed the SunSwift SBus Adapter in your system prior to performing the following tasks.
3 3.1 Preparing for Software Installation Note – If the CD-ROM drive that you are using for software installation is attached to a remote machine, refer to your SunOS installation guide for remote CD-ROM access. For Solaris 2.5 Systems Some newer systems are pre-loaded with the SunSwift SBus Adapter driver (hme). Before installing the driver from the CD-ROM, perform the following task.
3 3.2 Net-Install of Solaris 2.4 Over the hme Interface This section is only applicable if you are installing Solaris 2.4 on a net-install client system over the SunSwift SBus Adapter (hme) interface. Note – The Solaris 2.4 CD-ROM cannot be used to perform a net-install (read only), thus the Solaris 2.4 CD image archive is required to update certain SunSwift SBus Adapter files. Updating the Solaris 2.4 Archive to Use the hme Interface 1.
3 5. Complete the client installation. Refer to your Solaris documentation for detailed instructions. 6. Reboot the system. 7. Install the software drivers from the CD-ROM that came with the SunSwift SBus Adapter. Refer to the CD-ROM documentation that came with your adapter for driver installation instructions (Part No: 804-5303-10). 3.3 Host File Configuration After installing the SunSwift SBus Adapter software, you must create a hostname.hme file for its Ethernet interface.
3 2. Create an appropriate entry in the /etc/hosts file for each active hme channel. Using the example in step 1, you will have: zardoz # cat /etc/hosts ... 127.0.0.1 localhost 129.144.10.57 zardoz loghost 129.144.11.83 zardoz-11 129.144.12.41 zardoz-12 3.4 Caution: Package Dependency ! Caution – There is a package dependency with the SunSwift SBus Adapter. Before proceeding, perform the following task.
3 3.5 Booting The following sections discuss various ways of booting. See the section that applies to your specific needs. 3.5.1 Booting From the Network Using Solaris 2.5 To use the SunSwift SBus Adapter Ethernet interface as the boot device for Solaris 2.5 systems, perform the following tasks. 1. At the ok prompt type: ok show-devs The show-devs command lists the system devices.
3 3.5.2 Diskless Client Booting for Solaris 2.4 In order to boot a diskless client with a local SunSwift SBus Adapter interface (hme) on a Solaris 2.4 system, the following tasks must be performed on the boot server. 1. Go to your client’s root partition by typing the following: # cd /export/root//etc 2. Edit the name_to_major file by adding an entry for the SunSwift SBus Adapter device (hme).
3 3.5.3 Booting From the Network Using Solaris 2.4 The device name of newer SBus cards for Solaris 2.5 is identified by a “SUNW,” prefix. If your system is running Solaris 2.4, it will not recognize the device. Perform the following tasks to set up your system so the device driver can recognize the SunSwift SBus Adapter. 1. At the ok prompt type: ok setenv use-nvramrc? true ok show-devs The show-devs command lists the system devices.
3 6. Press the Stop-A keys to get to the ok prompt. 7. At the ok prompt, type show-devs to list your system devices and verify that the name property was changed correctly. You should see the full path name of the hme device, excluding SUNW, prior to hme, similar to the example below: /iommu@f,e0000000/sbus@f,e0001000/hme@3,8c00000 8. At the ok prompt, type: ok boot (full path name of the hme device) Installing SunSwift SBus Adapter Software On Solaris 2.4 and 2.
3 3.6 Post-Installation Procedures (Optional) Perform the tasks in the following sections to verify and customize the performance of the SunSwift SBus Adapter. 3.6.1 Using Hubs That Do Not Send Link Pulses Certain hubs are not compliant with the IEEE 802.3 Ethernet standards for link pulses, therefore do not send link pulses. To connect your system to these noncompliant hubs, you need to disable your system from looking for link pulses. 1.
3 3.6.2 Configuring Driver Parameters The hme device driver, which is loaded from the CD-ROM, controls the SUNW,hme Ethernet device. The device driver automatically selects the link speed using the auto-negotiation protocol with the link partner. (See Section 3.6.5, “Auto-Negotiation.
3 3.6.4 Forcing Network Speed Between 10 Mbps and 100 Mbps 1. At the ok prompt, use the show-devs command to list the system devices. You should see the full path name of the hme device, similar to the example below: /iommu@f,e0000000/sbus@f,e0001000/SUNW,hme@3,8c00000 2. Type: ok nvedit 3. Type the following, pressing the Return key at the end of line 0: 0: probe-all install-console banner 1: apply transfer-speed=10 (full path name of the hme device) 4.
3 3.6.5 Auto-Negotiation A key feature of the SunSwift SBus Adapter is auto-negotiation. The autonegotiation protocol, as specified by the 100BASE-T standard, automatically selects the operation mode (half-duplex or full-duplex) and speed (10 Mbps or 100 Mbps) for the adapter. The hme device driver operates the SUNW,hme device by default in half-duplex mode only.
