.SH DESCRIPTION
|
|
.B scsidump
|
|
has two modes of operation: dump and restore. These can be used with physical storage media, including hard drives and magneto optical drives. Dump mode can be used with read-only media such as CD/DVD drives.
|
|
|
|
When operating in dump mode, scsidump will copy all data from a remote SCSI drive to an image on the local filesystem. If enabled, it will also generate a .properties file that can be used to more closely emulate the source drive.
|
|
|
|
If you are operating in restore mode, scsidump will copy the data from a local binary image to a remote physical SCSI drive. The remote SCSI drive MUST be writable.
|
|
|
|
.SH NOTES
|
|
|
|
.B scsidump
|
|
requires either a direct connection (one without transceivers) or a FULLSPEC PiSCSI/RaSCSI board.
|
|
|
|
If the generated drive image is intended to be used with PiSCSI, the drive image should be moved by the user to ~/images (or the location specified to the piscsi service).
|

|
.SH OPTIONS
|
|
.TP
|
|
.BR \-t\fI " "\fIID[:LUN]
|
|
SCSI ID and optional LUN of the remote SCSI device. The remote SCSI device will be functioning as the "Target" device.
|
|
.TP
|
|
.BR \-i\fI " "\fIBID
|
|
SCSI ID of the PiSCSI device. If not specified, the PiSCSI device will use ID 7. The PiSCSI host will be functioning as the "Initiator" device.
|
|
.TP
|
|
.BR \-f\fI " "\fIFILE
|
|
Path to the dump file.
|
|
.TP
|
|
.BR \-s\fI " "\fIBUFFER_SIZE
|
|
The transfer buffer size, specified in bytes. Default is 1 MiB. This is specified in bytes with a minimum value of 65536 (64 KiB).
|
|
.TP
|
|
.BR \-r\fI
|
|
Run in restore mode. Defaults to dump mode if not specified.
|
|
.TP
|
|
.BR \-v\fI
|
|
Enable verbose logging.
|
|
.TP
|
|
.BR \-p\fI
|
|
Generate a .properties file that is compatible with the PiSCSI web interface. The output filename will match the image filename with ".properties" appended. The generated file should be moved to ~/.config/piscsi.

.SH EXAMPLES
|
|
Dump Mode: [SCSI Drive] ---> [PiSCSI host]
|
|
Launch scsidump to dump an all data from SCSI ID 3 with block size 64 KiB, store it to the local filesystem as a drive image named outimage.hda, and generate the outimage.hda.properties file with the drive's INQUIRY information:
|
|
scsidump -t 3 -f ./outimage.hda -s 65536 -p
|
|
|
|
Restore Mode: [PiSCSI host] ---> [SCSI Drive]
|
|
Launch scsidump to restore/upload a drive image from the local file system to SCSI ID 0 with block size 1MiB:
|
|
scsidump -r -t 0 -f ./outimage.hda -s 1048576
