NAME

     devinfo -- print information about system device configuration

SYNOPSIS

     devinfo [-rv]
     devinfo -u

DESCRIPTION

     The devinfo utility, without any arguments, shows the hierarchy of devices available in the system, starting from the ``nexus'' device.

     The following options are accepted.

     -r      Causes hardware resource information (such as IRQ, I/O ports, I/O memory addresses) to be also listed, under each device that has
	     reserved those resources.

     -u      Displays the same information as with -r but sorts by resource type rather than by device, allowing to review the set of system
	     resources by usage and available resources.  I.e., it lists all the IRQ consumers together.

     -v      Display all devices in the driver tree, not just those that are attached or busy.	Without this flag, only those devices that have
	     attached are reported.

NAME

       devinfo - print device specific information

SYNOPSIS

       /usr/sbin/devinfo -i device

       /usr/sbin/devinfo -p device

DESCRIPTION

       The  devinfo  command  is used to print device specific information about disk devices on standard out. The command can only be used by the
       superuser.

OPTIONS

       -i       Prints the following device information:

                  o  Device name

                  o  Software version (not supported and prints as 0)

                  o  Drive id number (not supported and prints as 0)

                  o  Device blocks per cylinder

                  o  Device bytes per block

                  o  Number of device partitions with a block size greater than zero

       -p       Prints the following device partition information:

                  o  Device name

                  o  Device major and minor numbers (in hexadecimal)

                  o  Partition start block

                  o  Number of blocks allocated to the partition

                  o  Partition flag

                  o  Partition tag

       This command is used by various other commands to obtain device specific  information for the making of file systems and determining parti-
       tion  information. If the device cannot be opened, an error message is reported.

OPERANDS

       device   Device name.

EXIT STATUS

       0        Successful operation.
