rascsi - Emulates SCSI devices using the Raspberry Pi GPIO pins

SYNOPSIS
|

rascsi [-F[u00AE] FOLDER] [-L[u00AE] LOG_LEVEL] [-h] [-n VENDOR:PROD‐
|

|
||
|
||
DESCRIPTION
|
||
rascsi Emulates SCSI devices using the Raspberry Pi GPIO pins.
|
||
|
||
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)
|
||
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)
|
||
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:
|
||
sudo rascsi -ID0 /path/to/drive/hdimage.hda
|
||
|
||
Once RaSCSI starts, it will open a socket (default port is 6868) to al‐
|
||
low 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 quit RaSCSI, press Control + C. If it is running in the background,
|
||
you can kill it using an INT signal.
|
||
|
||
OPTIONS
|
||
-b BLOCK_SIZE
|
||
The optional block size. For SCSI drives 512, 1024, 2048 or 4096
|
||
bytes, default size is 512 bytes. For SASI drives 256 or 1024
|
||
bytes, default is 256 bytes.
|
||
|
||
-F FOLDER
|
||
The default folder for image files. For files in this folder no
|
||
absolute path needs to be specified. The initial default folder
|
||
is '~/images'.
|
||
|
||
-L LOG_LEVEL
|
||
The rascsi log level (trace, debug, info, warn, err, critical,
|
||
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 re‐
|
||
turned with the INQUIRY data. A complete set of name components
|
||
must be provided. VENDOR may have up to 8, PRODUCT up to 16, RE‐
|
||
VISION up to 4 characters. Padding with blanks to the maxium
|
||
length is automatically applied. Once set the name of a device
|
||
cannot be changed.
|
||
|
||
-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 exten‐
|
||
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.
|
||
|
||
-HDn FILE
|
||
n is the SASI ID number (0-15)
|
||
|
||
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
|
||
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 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:
|
||
fallocate -l 104857600 /path/to/newimage.hda
