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 specifi-
cation, 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 (or names) to
the group definition. When invoked with both arguments and
the -d option, the command deletes the device name (or
names) 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. The options
and arguments for this command are:
-d Deletes the group or, if used with device, the
device from a group definition.
dgroup Specifies a device group name.
device Specifies the pathname or alias of the device that
is to added to or deleted from the device group.
ERRORS
The command will exit with one of the following values:
0 = successful completion of the task.
1 = command syntax incorrect, invalid option used, or inter-
nal 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.
