rascsi - Emulates SCSI devices using the Raspberry Pi GPIO pins
SYNOPSIS
rascsi [-f[u00AE] FOLDER] [-g[u00AE] LOG_LEVEL] [-h] [-n VENDOR:PRODUCT:REVISION] [-p[u00AE] PORT] [-r RESERVED_IDS] [-n TYPE] [-v] [-IDn FILE] [-HDn FILE]...

DESCRIPTION
rascsi Emulates SCSI devices using the Raspberry Pi GPIO pins.
In the arguments to RaSCSI, one or more SCSI (-IDn) or SASI (-HDn) devices can be specified. The number (n) after the ID or HD identifier specifies the ID number for that device.
For SCSI: The ID is limited from 0-7. However, typically SCSI ID 7 is reserved for the "initiator" (the host computer). Note that SASI is considered rare and only used on very
early Sharp X68000 computers.
In the arguments to RaSCSI, one or more SCSI (-IDn) or SASI (-HDn) de‐
vices can be specified. The number (n) after the ID or HD identifier
specifies the ID number for that device. For SCSI: The ID is limited
from 0-7. However, typically SCSI ID 7 is reserved for the "initiator"
(the host computer). Note that SASI is considered rare and only used on
very early Sharp X68000 computers.
RaSCSI will determine the type of device based upon the file extension of the FILE argument.
hdf: SASI Hard Disk image (XM6 SASI HD image - typically only used with X68000)
RaSCSI will determine the type of device based upon the file extension
of the FILE argument.
hdf: SASI Hard Disk image (XM6 SASI HD image - typically only used
with X68000)
hds: SCSI Hard Disk image (generic, non-removable)
hdr: SCSI Hard Disk image (generic, removable)
hdn: SCSI Hard Disk image (NEC GENUINE)
hdi: SCSI Hard Disk image (Anex86 HD image)
nhd: SCSI Hard Disk image (T98Next HD image)
hda: SCSI Hard Disk image (APPLE GENUINE - typically used with Mac SCSI emulation)
mos: SCSI Magneto-optical image (XM6 SCSI MO image - typically only used with X68000)
hda: SCSI Hard Disk image (APPLE GENUINE - typically used with Mac
SCSI emulation)
mos: SCSI Magneto-optical image (XM6 SCSI MO image - typically only
used with X68000)
iso: SCSI CD-ROM image (ISO 9660 image)
For example, if you want to specify an Apple-compatible HD image on ID 0, you can use the following command:
For example, if you want to specify an Apple-compatible HD image on ID
0, you can use the following command:
sudo rascsi -ID0 /path/to/drive/hdimage.hda
Once RaSCSI starts, it will open a socket (default port is 6868) to allow external management commands. If another process is using the rascsi port, RaSCSI will terminate, since
it is likely another instance of RaSCSI. Once RaSCSI has initialized, the rasctl utility can be used to send commands.

to send commands.
To quit RaSCSI, press Control + C. If it is running in the background, you can kill it using an INT signal.

The default folder for image files. For files in this folder no absolute path needs to be specified. The initial default folder is '~/images'.
-F FOLDER
The default folder for image files. For files in this folder no
absolute path needs to be specified. The initial default folder

off). The default log level is 'info'.
-h Show a help page.
-n VENDOR:PRODUCT:REVISION
Set the vendor, product and revision for the device, to be returned with the INQUIRY data. A complete set of name components must be provided. VENDOR may have up to 8,
PRODUCT up to 16, REVISION up to 4 characters. Padding with blanks to the maxium length is automatically applied. Once set the name of a device cannot be changed.

length is automatically applied. Once set the name of a device

-p PORT
The rascsi server port, default is 6868.
-r RESERVED_IDS
Comma-separated list of IDs to reserve. -p TYPE The optional case-insensitive device type (SAHD, SCHD, SCRM, SCCD, SCMO, SCBR, SCDP). If no type is specified for devices
that support an image file, rascsi tries to derive the type from the file extension.

sion.
-v Display the rascsi version.
-IDn FILE
n is the SCSI ID number (0-7)
FILE is the name of the image file to use for the SCSI device. For devices that do not support an image file (SCBR, SCDP) a dummy name must be provided.
FILE is the name of the image file to use for the SCSI device.

FILE is the name of the image file to use for the SASI device.
Note: SASI usage is rare, and is typically limited to early Unix workstations and Sharp X68000 systems.

EXAMPLES
Launch RaSCSI with no emulated drives attached:
rascsi
Launch RaSCSI with an Apple hard drive image as ID 0 and a CD-ROM as ID 2
Launch RaSCSI with an Apple hard drive image as ID 0 and a CD-ROM as ID
2
rascsi -ID0 /path/to/harddrive.hda -ID2 /path/to/cdimage.iso
Launch RaSCSI with a removable SCSI drive image as ID 0 and the raw device file /dev/hdb (e.g. a USB stick) and a DaynaPort network adapter as ID 6:
Launch RaSCSI with a removable SCSI drive image as ID 0 and the raw de‐
vice file /dev/hdb (e.g. a USB stick) and a DaynaPort network adapter
as ID 6:
rascsi -ID0 -t scrm /dev/hdb -ID6 -t scdp DUMMY_FILENAME
To create an empty, 100MB HD image, use the following command:
dd if=/dev/zero of=/path/to/newimage.hda bs=512 count=204800
In case the fallocate command is available a much faster alternative to the dd command is:
In case the fallocate command is available a much faster alternative to
