drvconfig(1M)

NAME

     drvconfig - configure the /devices directory

SYNOPSIS

     drvconfig   [-bn]   [-a alias_name]    [-c class_name]    [-
     i drivername] [-m major_num] [-r rootdir]

DESCRIPTION

     devfsadm(1M) is now the preferred command for /dev and /dev-
     ices and should be used instead of drvconfig.

     The default operation of drvconfig is to create the /devices
     directory  tree that describes, in the filesystem namespace,
     the hardware layout of a particular machine.  Hardware  dev-
     ices  present  on  the  machine  and  powered  on as well as
     pseudo-drivers are represented under /devices. Normally this
     command  is  run  automatically  after a new driver has been
     installed  (with  add_drv(1M))  and  the  system  has   been
     rebooted.

  /etc/minor_perm File
     drvconfig reads the /etc/minor_perm file to  obtain  permis-
     sion  information  and applies the permissions only to nodes
     that it has just created. It does not change permissions  on
     already  existing  nodes.  The format of the /etc/minor_perm
     file is as follows:

     name:minor_name permissions owner group

     minor_name may be the actual name of the minor node, or con-
     tain  shell  metacharacters to represent several minor nodes
     (see sh(1)).

     For example:

          sd:* 0640 root sys
          zs:[a-z],cu 0600 uucp uucp
          mm:kmem 0640 root bin

     The first line sets all devices exported by the sd  node  to
     0640  permissions,  owned  by  root,  with group sys. In the
     second line, devices such as a,cu  and  z,cu exported by the
     zs  driver  are  set to 0600 permission, owned by uucp, with
     group uucp. In the third line the kmem  device  exported  by
     the mm driver is set to 0640 permission, owned by root, with
     group bin.

OPTIONS

     The following options are supported:

     -a alias_name
           Add the name alias_name to the list  of  aliases  that
           this  driver  is known by.  This option, if used, must
           be used with the -m  major_num,  the  -b  and  the  -i
           drivername options.

     -b    Add a new  major  number  to  name  binding  into  the
           kernel's   internal name_to_major tables.  This option
           is not normally used directly, but is  used  by  other
           utilities  such  as  add_drv(1M). Use of the -b option
           requires that -i and -m  be  used  also.  No  /devices
           entries are created.

     -c class_name
           The driver being added to the system exports the class
           class_name. This option is not normally used directly,
           but is used by other utilities. It is  only  effective
           when used with the -b option.

     -i drivername
           Only configure the devices for the named  driver.  The
           following  options  are  used by the implementation of
           add_drv(1M) and rem_drv(1M), and may not be  supported
           in future versions of Solaris:

     -m major_num
           Specify the major number major_num for this driver  to
           add to the kernel's name_to_major binding tables.

     -n    Do not try to load and attach any drivers, or  if  the
           -i  option  is  given, do not try to attach the driver
           named drivername.

     -r rootdir
           Build the device tree under the directory specified by
           rootdir instead of the default /devices directory.

EXIT STATUS

     0     Successful completion.

     non-zero
           An error occurred.
