What You Need for Unsupported Devices
Device drivers needed to support a wide range of standard devices are included in the Solaris environment. These drivers can be found in the /kernel/drv and /platform/`uname -m`/kernel/drv directories.
However, if you've purchased an unsupported device, the manufacturer should provide the software that is needed for the device to be properly installed, maintained, and administered.
At a minimum, this software includes a device driver and its associated configuration (.conf) file. The .conf files reside in the drv directories. This software might also include custom maintenance and administrative utilities since the device might be incompatible with Solaris utilities.
Contact your device manufacturer for more information.
Displaying Device Configuration Information
Three commands are used to display system and device configuration information.
Command | Man Page | Description |
---|---|---|
prtconf | prtconf(1M) | 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 | sysdef(1M) | Displays device configuration information including system hardware, pseudo devices, loadable modules, and selected kernel parameters. |
dmesg | dmesg(1M) | Displays system diagnostic messages as well as a list of devices attached to the system since the last reboot. |
For information on the device names that are used to identify devices on the system, see "Device Naming Conventions".
driver not attached Message
The following driver-related message might 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. This message 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 the 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 . . . esp, instance #0 sd (driver not attached) st (driver not attached) sd, instance #0 (driver not attached) sd, instance #1 (driver not attached) sd, instance #2 (driver not attached) sd, instance #3 sd, instance #4 (driver not attached) sd, instance #5 (driver not attached) sd, instance #6 . . . |
You can glean the same device information 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 that include 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 based system.
