.
|
||||
.SH DESCRIPTION
|
||||
.B chzdev
|
||||
is a tool for configuring devices and device drivers which are specific to the
|
||||
IBM z Systems platform. Supported device types include storage devices (DASD
|
||||
and zFCP) and networking devices (QETH, CTC and LCS).
|
||||
.PP
|
||||
.
|
||||
.SS "Configurations"
|
||||
You can apply configuration changes to the active configuration of the
|
||||
currently running system, or to the persistent configuration stored in
|
||||
configuration files:
|
||||
.IP \(bu 3
|
||||
Changes to the
|
||||
.B "active configuration"
|
||||
are effective immediately. They are lost on reboot, or when a device becomes
|
||||
unavailable, or when a device driver is unloaded.
|
||||
.PP
|
||||
.IP \(bu 3
|
||||
Changes to the
|
||||
.B "persistent configuration"
|
||||
are applied when the system boots, or when a device becomes available, or
|
||||
when a device driver is loaded.
|
||||
.PP
|
||||
By default chzdev applies changes to both the active and the persistent
|
||||
configuration.
|
||||
.PP
|
||||
.
|
||||
.SS "Tool actions"
|
||||
chzdev supports multiple
|
||||
.B tool actions
|
||||
such as
|
||||
.IP \(bu 3
|
||||
Enable a device.
|
||||
.PP
|
||||
.IP \(bu 3
|
||||
Disable a device.
|
||||
.PP
|
||||
.IP \(bu 3
|
||||
Export and import configuration data to and from a file.
|
||||
.PP
|
||||
.IP \(bu 3
|
||||
Display a list of available device types and attributes.
|
||||
.PP
|
||||
You can trigger these actions by specifying one of the command line options
|
||||
listed in the ACTIONS section.
|
||||
.PP
|
||||
.
|
||||
.
|
||||
.SH TYPE
|
||||
chzdev uses
|
||||
.B "device type"
|
||||
names to distinguish devices by their respective type.
|
||||
A device type typically corresponds to a device driver, though there are cases
|
||||
where multiple device types are provided for the same driver (for example both
|
||||
device types "dasd-eckd" and "dasd-fba" are related to the DASD device driver).
|
||||
.PP
|
||||
You can use the
|
||||
.B TYPE
|
||||
positional argument of the chzdev tool to restrict the scope of a tool action
|
||||
to the specified device type:
|
||||
.IP \(bu 3
|
||||
Specify a device type and optionally a device ID to only work on
|
||||
devices with matching type and ID
|
||||
.PP
|
||||
.IP \(bu 3
|
||||
Specify a device type together with option
|
||||
.nh
|
||||
\-\-type
|
||||
.hy
|
||||
to manage the configuration of the device type itself
|
||||
.PP
|
||||
.B Note:
|
||||
Specify the full device type when configuring a device by
|
||||
ID. Otherwise the same device ID might accidentally match other devices of a
|
||||
different type.
|
||||
.PP
|
||||
To get a list of supported device types, use the
|
||||
.nh
|
||||
\-\-list\-types
|
||||
.hy
|
||||
action.
|
||||
.PP
|
||||
.
|
||||
.
|
||||
.SH DEVICE
|
||||
Use the
|
||||
.B DEVICE
|
||||
positional argument of chzdev to select a single device or a range of devices
|
||||
by device ID as target for a tool action. To select a range of devices, specify
|
||||
the ID of the first and the last device in the range separated by a hyphen (-).
|
||||
Separate multiple IDs or ranges with a comma (,).
|
||||
.PP
|
||||
.B Example:
|
||||
.CL chzdev dasd 1000,2000-2010 -e
|
||||
.PP
|
||||
.
|
||||
.
|
||||
.SH SELECTION
|
||||
In addition to specifying devices by their ID you can also select devices by
|
||||
their state or by the Linux functions they provide.
|
||||
.PP
|
||||
chzdev supports the following device states:
|
||||
.PP
|
||||
.TP 12
|
||||
.B online
|
||||
The device is enabled in the active configuation and set up to provide a Linux
|
||||
function such as a block device like /dev/dasda, or a networking interface like
|
||||
eth0.
|
||||
.PP
|
||||
.TP 12
|
||||
.B offline
|
||||
The device is not enabled in the active configuration.
|
||||
.PP
|
||||
.TP 12
|
||||
.B existing
|
||||
The device is present in the active configuration.
|
||||
.PP
|
||||
.TP 12
|
||||
.B configured
|
||||
There is a persistent configuration for this device.
|
||||
.PP
|
||||
.TP 12
|
||||
.B failed
|
||||
The driver of a device detected errors that may cause the device to not function
|
||||
properly.
|
||||
.PP
|
||||
.
|
||||
Selection works in two stages:
|
||||
.PP
|
||||
.IP 1. 3
|
||||
All devices specified by ID or by options
|
||||
.nh
|
||||
\-\-all, \-\-by\-interface, \-\-by\-node or \-\-by\-path
|
||||
.hy
|
||||
are considered for selection.
|
||||
.PP
|
||||
.IP 2. 3
|
||||
Of the considered devices, only those matching the specified state options
|
||||
.nh
|
||||
\-\-online, \-\-offline, \-\-existing, \-\-configured and \-\-failed
|
||||
.hy
|
||||
are selected.
|
||||
.PP
|
||||
.
|
||||
.

with a value of
|
||||
.IR VALUE .
|
||||
When specified as
|
||||
.IR KEY != VALUE ,
|
||||
selects all devices that
|
||||
.B don't
|
||||
provide an attribute named
|
||||

|
||||
|
||||
.B Note:
|
||||
If
|
||||
.I NODE
|
||||
is the device node for a logical device (such as a device mapper device),
|
||||
chzdev will try to resolve the corresponding physical device nodes. The
|
||||
.MP lsblk 8
|
||||
tool must be available for this resolution to work.
|
||||
.PP
|
||||
.
|
||||
.OD by-path "" "PATH"
|
||||
Select device providing file system path, e.g. /usr.
|
||||
|
||||
The
|
||||
.I PATH
|
||||
parameter can be the mount point of a mounted file system, or a path
|
||||
on that file system.
|
||||
|
||||
.B Note:
|
||||
If the file system that provides
|
||||
.I PATH
|
||||
is stored on multiple physical devices or on a subvolume (such as supported by
|
||||
btrfs) chzdev will try to resolve the corresponding physical device nodes. The
|
||||
.MP lsblk 8
|
||||
and
|
||||
.MP findmnt 8
|
||||
tools must be available and in the case of multiple physical devices the file

.OD failed "" ""
|
||||
Select devices for which errors were detected.
|
||||
|
||||
A failed device is a device for which its driver detected an error condition
|
||||
that may cause the device to not correctly perform its function. You can use
|
||||
the \-\-info option of the lszdev tool to get more details on the detected
|
||||
errors.
|
||||
|

|
||||
|
||||
By default all configuration data that is read is also applied. To reduce the
|
||||
scope of imported configuration data, you can select specific devices, a device
|
||||
type, or define whether only data for the active or persistent configuration
|
||||
should be imported.
