Diagnostic Console Bootup Messages

Prior to version 4.0, CC-SG Diagnostic Console displays a number of messages on the screen each time when it boots up. These messages are standard Linux diagnostic and warning messages and usually do not imply any system problems. The table offers a short introduction to a few frequent messages.

Message

Description

hda:

The message indicates that something on the system is trying to communicate with the DVD-ROM drive. Different scenarios can invoke the message. For example:

  • A user opens or closes the DVD-ROM drive door, or
  • The operating system is checking the DVD-ROM drive and finds no media when it boots up.

    There are other scenarios that invoke the message as well but will not be described in the section.

avc:

The message comes from an internal security audit and control system -- SELinux sub-system. The system issues warnings without enforcing any security policy so they do not indicate any problem with the system.

ipcontracks:

The message always appears each time CC-SG boots up so it is normal.

Note that CC-SG turns off these messages since version 4.0, but they are still available in internal logs. Therefore, when you upgrade CC-SG from 3.x to 4.x, these Diagnostic Console messages disappear.
