PUTDGRP(8) Maintenance Commands and Procedures PUTDGRP(8)
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.
