Function Description

The Black Box page allows you to enable or disable the black box function and download data from the black box memory.

A black box consists of memory and fault monitoring software.
  • The memory is a built-in storage chip that records fault information, independent of hard disks on the server.

    The memory provides a maximum of 4 MB storage capacity, and saves kernel information when the OS crashes.

  • The fault monitoring software records kernel information when the OS crashes.

    Before using the black box function, ensure that the fault monitoring software (for example, iBMA) has been installed on the server. For details about how to install and use the iBMA, see iBMA User Guide.

  • If the black box driver has not been installed on V5 servers after the black box function is enabled, unknown devices may be detected on the OS.


Choose Diagnostics from the main menu, and select Black Box from the navigation tree.

The Black Box page is displayed.
