LPI Linux Certification/Setup Non IDE Devices

Detailed Objective

Weight: 1

Description:
Candidates should be able to configure non-IDE devices such as SCSI, SATA, USB drives using the special BIOS as well as the necessary Linux tools.

• Key knowledge area(s):
  • Differentiate between the various types of non-IDE devices.
  • Manipulate BIOS to detect used and available SCSI IDs.
  • Set the correct hardware ID for different devices, especially the boot device.
  • Configure BIOS settings to control the boot sequence when both non-IDE and IDE devices are present .

• The following is a partial list of the used files, terms and utilities:
  • SCSI ID
  • /proc/scsi/
  • scsi_info

SCSI

The SCSI BIOS can be accessed at boot time with some special key sequences (Ctrl+A for most Adaptec Host Bus Adapters, Ctrl+G, Ctrl+M, or other keys for other vendors) and allow you to setup some parameters. Bootable SCSI and more.

In order to get SCSI information, use scsi_info or hdparm.

Examples:

scsi_info /dev/sda
hdparm -grv /dev/sda

obs: Tested with hdparm v6.1 (debian sarge kernel 2.6.8-3 arch 386)
