Determining the Devices Installed on Your Server

109

To see the hardware graph, use the

ls

 command. For example:

# ls /hw

console       input2        mmem          scsi          zero

cpunum        kmem          module        scsi_ctlr

disk          machdep       nodenum       tape

external_int  mem           null          ttys

input         midi          rdisk         unknown

The contents of the directories can be either IRIX special device files or subdirectories. In
this output, for example,

ttys

,

scsi

,

rdisk

, and

scsi_ctrl

 are subdirectories

containing files:

# ls /hw/ttys
