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 specification, the command adds the specified group name to the device  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. Otherwise, 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.
