putdgrp(1M) System Administration Commands putdgrp(1M)NAMEputdgrp - edits device group table
SYNOPSISputdgrp [-d] dgroup [device...]
DESCRIPTIONputdgrp modifies the device group table. It performs two kinds of modi‐
fication. 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 com‐
mand 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 specifica‐
tion, 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 specifica‐
tion 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 spec‐
ified devices. Otherwise, indicates that the device group
dgroup already has one or more of the specified devices as
members.
