System Administration Commands                        putdgrp(1M)



NAME
     putdgrp - edits device group table

SYNOPSIS
     putdgrp [-d] dgroup [device]...


DESCRIPTION
     putdgrp modifies the device group  table.  It  performs  two
     kinds  of modification. It can modify the table  by creating
     a new device group or removing a device group. It  can  also
     change  group  definitions  by   adding or removing a device
     from the group definition.


     When the command is invoked with only  a  dgroup  specifica-
     tion,  the command adds the specified group name to the dev-
     ice group table if it does not  already  exist.  If  the  -d
     option  is also used with only the dgroup specification, the
     command deletes the group from the table.


     When the command is invoked with both a dgroup and a  device
     specification, it adds the given device name(s) to the group
     definition. When invoked with  both  arguments  and  the  -d
     option,  the  command  deletes  the  device name(s) from the
     group definition.


     When the command is invoked with both a dgroup and a  device
     specification  and  the  device  group  does  not  exist, it
     creates the group and adds the specified devices to that new
     group.

OPTIONS
     The following options are supported:

     -d    Delete the group or, if used with device,  delete  the
           device  from a group definition.


OPERANDS
     The following operands are supported:

     dgroup    Specify a device group name.


     device    Specify the pathname or alias of the  device  that
               is  to  be  added  to, or deleted from, the device
               group.

EXIT STATUS
     The following exit values are returned:

     0    Successful completion.


     1    Command syntax was incorrect,  an  invalid  option  was
          used,  or an internal error occurred.


     2    Device group table could not be opened for reading or a
          new device group table could not be created.


     3    If executed with the   -d  option,  indicates  that  an
          entry  in  the  device group table for the device group
          dgroup does not exist and so cannot be deleted.  Other-
          wise,  indicates  that the  device group dgroup already
          exists and cannot be added.


     4    If executed with the  -d  option,  indicates  that  the
          device  group  dgroup  does  not have as members one or
          more of the  specified  devices.  Otherwise,  indicates
          that  the  device group  dgroup already has one or more
          of the specified devices as members.
