putdgrp - edits device group table
putdgrp [ -d ] dgroup [
device ... ]
SUNWcsu
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.
- -d
- Delete the group
or, if used with device, delete the device from a group definition.
- 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.
The
command will exit with one of the following values:
- 0 =
- successful completion
of the task.
- 1 =
- command syntax incorrect, invalid option used, or 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.
