Checking Installed Hardware With hinv

Checking Installed Hardware With hinv

The hinv command displays the workstation or server's hardware inventory. This command can be run from the Command (PROM) Monitor or from your system shell prompt. Pertinent information such as the processor type, amount of main memory, and all disks, tape drives, or other devices is included. A sample hinv output for a typical workstation is:

If a piece of peripheral hardware installed on your system does not appear in the hinv output, it may or may not be an indication of trouble with your hardware. Some peripherals connected to the system by a board on a VME bus will not be identified when running hinv from the Command Monitor. First, you should invoke hinv from a system shell prompt; If your peripheral is still not recognized, attempt to reseat the board or device in its socket and check that it is using the correct SCSI address. If this does not relieve the problem, the hardware itself may be defective. Note also that most devices are not recognized by hinv until the MAKEDEV(1M) command has been run after their installation.
