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 idnetifier 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.

puters.
|

RaSCSI will determin the type of device based upon the file extension of the FILE argument.

|

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 (port 6868) to allow external management commands. If another
|
||||
process is using port 6868, RaSCSI will terminate, since it is likely another instance of RaSCSI. Once
|

RaSCSI has initialized, the rasctl utility can be used to send commands.
