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.

EXAMPLES

     Example 1: Adding a new device group.

     The following example adds a new device group:

     Example 2: Adding a device to a device group.

     The following example adds a device to a device group:

     example#  putdgrp floppies diskette2

     Example 3: Deleting a device group.

     The following example deletes a device group:

     example#  putdgrp -d floppies

     Example 4: Deleting a device from a device group.

     The following example deletes a device from a device group:
