NAME

       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

NAME

       mkdevalloc - Make device_allocate entries

SYNOPSIS

       /usr/sbin/mkdevalloc

DESCRIPTION

       The mkdevalloc command writes to standard out a set of device_allocate(4) entries describing the system's frame buffer, audio and removable
       media devices.

       The mkdevalloc command is used by the init.d(4) scripts to create or update the /etc/security/device_allocate file.

       Entries are generated based on the device special files found in /dev. For the different categories  of	devices,  the  mkdevalloc  command
       checks for the following files under /dev:

       audio	       /dev/audio, /dev/audioctl, /dev/sound/...
       tape	       /dev/rst*, /dev/nrst*, /dev/rmt/...
       floppy	       /dev/diskette, /dev/fd*, /dev/rdiskette, /dev/rfd*
       removable disk  /dev/sr*, /dev/nsr*, /dev/dsk/c0t?d0s?, /dev/rdsk/c0t?d0s?
       frame buffer    /dev/fb

       All  entries  set  the  device-minimum  and device-maximum fields to the hex representations of ADMIN_LOW and ADMIN_HIGH, respectively. The
       device-authorization field is set to solaris.device.allocate, except for the framebuffer entry, where it is  set  to  *.  The  device-name,
       device-type and device-clean fields are set to the following values:

		       device-name	device-type   device-clean

       audio	       audio		audio	      audio_clean_wrapper
       tape	       mag_tape_0,1,... st	      st_clean
       floppy	       floppy_0,1,...	fd	      disk_clean
       removable disk  cdrom_0,1,...	sr	      disk_clean
       frame buffer    framebuffer	fb	      /bin/true
