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.
