The Sun Device Detection Tool can help you to determine if the Devices on the system is detected by the Sun Solaris Operating System.
If your device or system is already on the Hardware Compatibility List (HCL) then this may not be necessary. Click here for the HCL in Sun Solaris.
However, there is no harm in running the tool. The tool also allows you to submit the device to HCL under the Reported to Work Function (RWF).
