2.3 Configuring I/O devices
This section describes the tasks required to enable the SCSI/SAS target driver to identify
disk devices. In the explanation here, these tasks are discussed based on the assumption
that the sd driver (SCSI disk driver) is used.
Please refer to the manual of each device for the definition of the control driver of other
I/O devices such as tape drive.
2.3.1 Collecting information about the devices to be connected
First, collect the following information about the devices that will be connected:
SCSI target ID for each device
Logical unit (LU: Logical Unit) number included with each device
WWID of HBA (SAS)
Information on the device with which the server for the installation is connected by
executing "probe‑scsi‑all" on OBP can be confirmed.
{0} ok probe‑scsi‑all

2.3.2 Editing the sd.conf
The definition file for the sd driver is /kernel/drv/sd.conf add the collected information
to this file. sd.conf contains several default settings.
