Fails with an error message indicating that the signal 11 was received.Hangs after the OS requests an IP address from the PXE server.When PXE installing a blade, the installer does one of the following: Installer Hangs or Fails During PXE Boot Installation To unmount all file systems and enable the blade to reboot correctly, ensure that you press Enter at the final OK prompt during the PXE boot installation. When booting the blade from the disk for the first time, the blade runs fsck to fix filesystems. The BIOS is configured to boot from the network by default.Īt the SC prompt, use the bootmode reset_nvram sn command to reset the BIOS to boot from the disk by default. You must re-install the blade.Īfter successfully completing a PXE boot installation, the blade continues to boot from the network instead of the disk. This problem may occur if the blade is removed or powered off during installation. The PXE boot installation did not complete. GRUB version 0.92 (634K lower / 522176K upper memory) Root Password Message After Installing the Linux Kernelĭuring a PXE boot installation, the following message appears after loading the Linux kernel: An exact match is necessary to ensure that module versioning does not cause the 5704 network driver ( suntg3) to fail to load. This occurs if the linux distribution installed on the PXE server does not exactly match the linux distribution against which the supplemental CD (supplied with the Linux blade) was built. If the NFS services are working normally and can be used from other machines on the network, it is likely that the PXE server has provided the wrong kernel to the blade. See the Sun Fire B1600 Chassis Administration Guide for information on installing the SSC. If you have only one switch and system controller (SSC) installed on the chassis, ensure that the SSC is installed in position 0. This problem may also occur if the blade is not correctly connected to the PXE server. If this path is not in the output, check your NFS setup and configuration. Currently only 'octet' mode of transfering files to TFTP server is supported.# showmount -e Export list for PXE-server : /tftp (everyone).Asynchronous API for background file download/upload.TFTP client which supports option extension and octet transmission mode.The following sections describe the specifics and limitations to the current implementation. Disabling these checks might improve performance. These checks are useful during development phase, but they might be redundant when the application is finalized. Set this define to 1 to disable checks on API parameters in the module.ĪPI parameter checks are added to ensure that the correct parameters are passed to the module. Descriptionĭisables API parameter checks in the module. To enable tracing, this flag must be set to 0 and NRF_LOG_ENABLED must be set to 1. The following configuration parameters should be defined in sdk_config.h.ĭisables debug tracing in the module. The following sections describe TFTP transactions and show how to use this module.įigure 1 shows the negotiation procedure between the TFTP client and TFTP server. The application has to use at least one IoT File port to be able to use this module. The retry mechanism requires the IoT Timer module to be present. Therefore, an additional UDP socket has to be allocated for each TFTP instance to work. Note The TFTP module is implemented on top of the User Datagram Protocol (UDP) module. These features enable files to be downloaded/uploaded in blocks with negotiated size and to control transmission speed.įor more information see the References section. This module supports several extensions like negotiating connection parameters, informing about file size, and setting a retransmission interval. The module sends requests to the server and manages file transfers using File abstraction. The TFTP client module provides the functionality for both sending and retrieving files from the file server using Trivial File Transfer Protocol which uses UDP as a transport layer. This information applies to the following SoftDevice: S132
