Displaying Device Configuration Information
Three commands are used to display system and device configuration information:
|
prtconf |
Displays system configuration information, including total amount of memory and the device configuration as described by the system's device hierarchy. The output displayed by this command depends upon the type of system. |
|
sysdef |
Displays device configuration information including system hardware, pseudo devices, loadable modules, and selected kernel parameters. |
|
dmesg |
Displays system diagnostic messages as well as a list of devices attached to the system since the last reboot. |
See "Device Naming Conventions" for information on the device names used to identify devices on the system.
driver not attached Message
The following driver-related message may be displayed by the prtconf and sysdef commands:
device, instance #number (driver not attached) |
This message does not always mean that a driver is unavailable for this device. It means that no driver is currently attached to the device instance because there is no device at this node or the device is not in use. Drivers are loaded automatically when the device is accessed and unloaded when the device is not in use.
Identifying a System's Devices
Use the output of prtconf and sysdef commands to identify which disk, tape, and CD-ROM devices are connected to the system. The output of these commands display the driver not attached messages next to the device instances. Since these devices are always being monitored by some system process, the driver not attached message is usually a good indication that there is no device at that device instance.
For example, the following prtconf output identifies a device at instance #3 and instance #6, which is probably a disk device at target 3 and a CD-ROM device at target 6 of the first SCSI host adapter (esp, instance #0).
$ /usr/sbin/prtconf

The same device information can be gleaned from the sysdef output.
How to Display System Configuration Information
Use the prtconf command to display system configuration information.
# /usr/sbin/prtconf |
Use the sysdef command to display system configuration information including pseudo devices, loadable modules, and selected kernel parameters.
# /usr/sbin/sysdef |
Examples--Displaying System Configuration Information
The following prtconf output is displayed on a SPARC system.

How to Display Device Information
Display device information with the dmesg command.
# /usr/sbin/dmesg |
The dmesg output is displayed as messages on the system console and identifies which devices are connected to the system since the last reboot.
Examples--Displaying Device Information
The following dmesg output is displayed from a SPARC system.
