OS Present diagnostics

This topic provides an overview of the adapter diagnostics that are available to with the SAN File System.

In addition to the firmware diagnostics provided with the engine, the SAN File System provides an additional set of OS Present diagnostics that enable you to test the following adapter cards that are installed in the engine:
  • Fibre-channel adapter
  • Ethernet adapter
  • Remote Supervisor Adapter (RSA) II
  • System board Ethernet ports

The OS Present diagnostics check that device drivers are installed and operational. In addition, you can use OS Present diagnostics to view the error log from adapter diagnostics tests; obtain vital product data for adapters, processors, memory, and system board; view information from the RSA II event log; and view a listing of changes that have been made to hardware devices, their firmware, or device driver versions.

You can access the OS Present diagnostics using the diags command, which provides a menu-driven interface to the list of devices in the engine. For each available device, you can run diagnostic tests, as well as view information about the device and the tests that are run.

In addition, OS Present diagnostics provide tools for viewing logs directly from the command line:
  • The delog command displays the latest diagnostics error log.
  • The elog command displays the RSA II log.
  • The vpdlog command displays vital product information about the devices.
