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.
