NAME

6       putdgrp - edits device group table

SYNOPSIS

9       putdgrp [-d] dgroup [device]...
10
11

DESCRIPTION

13       putdgrp modifies the device group table. It performs two kinds of modi‐
14       fication. It can modify the table  by creating a new  device  group  or
15       removing  a  device  group.  It  can  also  change group definitions by
16       adding or removing a device from the group definition.
17
18
19       When the command is invoked with only a dgroup specification, the  com‐
20       mand adds the specified group name to the device group table if it does
21       not already exist. If the -d option is also used with only  the  dgroup
22       specification, the command deletes the group from the table.
23
24
25       When  the command is invoked with both a dgroup and a device specifica‐
26       tion, it adds the given device name(s) to the  group  definition.  When
27       invoked  with both arguments and the -d option, the command deletes the
28       device name(s) from the group definition.
29
30
31       When the command is invoked with both a dgroup and a device  specifica‐
32       tion and the device group does not exist, it creates the group and adds
33       the specified devices to that new group.
34

OPTIONS

36       The following options are supported:
37
38       -d    Delete the group or, if used with device, delete the device  from
39             a group definition.

41

OPERANDS

43       The following operands are supported:
44
45       dgroup    Specify a device group name.
46
47
48       device    Specify  the  pathname  or  alias of the device that is to be

EXIT STATUS

53       The following exit values are returned:
54
55       0    Successful completion.
56

59            internal error occurred.
60
61
62       2    Device group table could not be opened for reading or a new device
63            group table could not be created.
64
65
66       3    If executed with the  -d option, indicates that an  entry  in  the
67            device group table for the device group  dgroup does not exist and
68            so cannot be deleted. Otherwise, indicates that the  device  group
69            dgroup already exists and cannot be added.
70
71
72       4    If  executed  with the  -d option, indicates that the device group
73            dgroup does not have as members  one  or  more  of  the  specified
74            devices.  Otherwise,  indicates  that  the  device  group   dgroup
75            already has one or more of the specified devices as members.
