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 set up 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)
