Types ¶

type CDB10 ¶

type CDB10 [10]byte

type CDB16 ¶

type CDB16 [16]byte

type CDB6 ¶

type CDB6 [6]byte

SCSI CDB types

type Device ¶

type Device interface {
	Open() error
	Close() error
	PrintSMART(*drivedb.DriveDb, io.Writer) error
}

Top-level device interface. All supported device types must implement these methods.

func OpenSCSIAutodetect ¶

func OpenSCSIAutodetect(name string) (Device, error)

type InquiryResponse ¶

type InquiryResponse struct {
	Peripheral byte // peripheral qualifier, device type

	Version byte

	VendorIdent  [8]byte
	ProductIdent [16]byte
	ProductRev   [4]byte
	// contains filtered or unexported fields
}

SCSI INQUIRY response

func (InquiryResponse) String ¶

func (inq InquiryResponse) String() string

type SATDevice ¶

type SATDevice struct {
	SCSIDevice
}

SATDevice is a simple wrapper around an embedded SCSIDevice type, which handles sending ATA commands via SCSI pass-through (SCSI-ATA Translation).

func (*SATDevice) PrintSMART ¶

func (d *SATDevice) PrintSMART(db *drivedb.DriveDb, w io.Writer) error

type SCSIDevice ¶

type SCSIDevice struct {
	Name string
	// contains filtered or unexported fields
}

TODO: Make a constructor function for this.

func (*SCSIDevice) Close ¶

func (d *SCSIDevice) Close() error

func (*SCSIDevice) Open ¶

func (d *SCSIDevice) Open() (err error)

func (*SCSIDevice) PrintSMART ¶

func (d *SCSIDevice) PrintSMART(db *drivedb.DriveDb, w io.Writer) error

Regular SCSI (including SAS, but excluding SATA) SMART functions not yet fully implemented.
