TGTD(8) [FIXME: manual] TGTD(8)NAME
tgtd - The SCSI Target Daemon
SYNOPSIS
tgtd
tgtd [-C --control-port <INTEGER>] [-d --debug <INTEGER>] [-f --foregound] [-h --help] [--iscsi <...>]
DESCRIPTION
Tgtd is a SCSI Target daemon. It can be used to provide SCSI target service to a network. The most common service is iSCSI but other
services are also supported.
DEVICE TYPES
Tgtd provides support for both emulated and passthrough of real devices.
Tgtd can emulate the following types of devices:
disk : Normal disk device. Emulates a SCSI harddisk.
tape : Tape device. Emulates a SCSI tape drive.
cd : CD device. Emulates a SCSI DVD burner.
changer : Media changer. Emulate the changer device for a virtual tape library or DVD jukebox.
OPTIONS -d --debug <INTEGER>
Set to non-zero value to activate additional debugging messages to be logged.
-f --foreground
Run the daemon in the foreground.
-h --help
Print help text to the screen.
-C --control-port <INTEGER>
This comamnd is used to specify the control port to use for this instance of tgtd. This allows to run multiple instances of TGTD on a
host.
TGTADM has a matching argument to control which instance to connect to.
--iscsi <...>
ISCSI specific options. See the ISCSI section below for options specific to this frontend.
ISCSI OPTIONS
These parameters apply only to the iSCSI frontend.
portal=<ip-address[:port]>
This option is used to bind tgtd to a specific ip-address/portal and/or port. By default tgtd will bind to port 3260 on the wildcard
address. The ip-address part (before the ":") can be missing to designate the wildcard address with a none-default port.
Example: to bind tgtd to a specific address and port
tgtd --iscsi portal=192.0.2.1:3260
Example: to bind tgtd to any address but a none-default port
tgtd --iscsi portal=:3251

tgtimg - Linux SCSI Target Framework Image File Utility
SYNOPSIS
tgtimg [-o --op <operation>] [-Y --device-type <device-type>] [-b --barcode <barcode>] [-s --size <size>] [-t --type <media-type>]
[-f --file <path>]
tgtimg --help
DESCRIPTION
Tgtimg is a utility to create and manage the image files used by the TGTD device emulation.
This command is used to initialize device image files with the additional metadata, such as barcode, list of blocks, total size, etc that
the TGTD emulation needs.
OPTIONS -h, --help
Show a help screen and exit.
-o, --op {new|show}
Operation. Is either new to create a new image file or show to show the content of an existing image file.
-Y, --device-type <type>
This specifies the type of image file.
Supported device types are :
cd : to create media for a dvd device
disk : to create media for a disk device
tape : to create media for a tape device
-t, --type <media-type>
When creating a new image, this specifies the type of media to emulate. The available mediatypes depend on the type of the device.
Supported media types for cd devices are :
dvd+r : create a blank writeable DVD+R disk
Supported media types for disk devices are :
disk : create an empty disk
Supported media types for tape devices are :
data : create a normal data tape
clean : create a cleaning tape
worm : create a worm
-b, --barcode <barcode>
When creating a new image, this argument specifies the barcode to use with this image file. Backup application software often uses
barcodes to identify specific tapes. When emulating a VTL, make sure that all tape images use unique barcodes.
-s, --size <size>
When creating a new image, this specifies the size in megabytes for the virtual tape image.
-f, --file <path>
The filename of the image file.
EXAMPLES
To create a new 100MByte disk
tgtimg --op new --device-type disk --type disk --size 100 --file /data/hd001.raw
To create a new tape image
tgtimg --op new --device-type tape --barcode 12345 --size 100 --type data --file /data/tape001.img
To view the content of an existing image
tgtimg --op show --device-type tape --file /data/tape001.img
To create a new blank DVD+R image
tgtimg --op new --device-type cd --type dvd+r --file /data/dvd001.iso
