LPI Linux Certification/Setup Non IDE Devices
Detailed Objective
Weight: 1
Description:
Candidates should be able to configure non-IDE devices 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)
