Golang Message Examples

Example #1

File: lun.go Project: kurin/tgt

func (t *Target) handleVPD(s *Session, m, resp *packet.Message) {
	lun := int(m.LUN)
	alloc := int(packet.ParseUint(m.CDB[3:5]))
	vpd, err := t.LUNs[lun].VitalProductData(m.CDB[2])
	if err != nil {
		resp.Status = 0x02
		resp.SCSIResponse = 0x01
		return
	}
	resp.RawData = vpd
	if len(vpd) >= alloc {
		resp.RawData = resp.RawData[:alloc]
	}
}

Example #2

File: lun.go Project: kurin/tgt

func setError(resp *packet.Message, serr SCSIError) {
	buf := &bytes.Buffer{}
	data := serr.Bytes()
	buf.Write(packet.MarshalUint64(uint64(len(data)))[6:])
	buf.Write(data)
	resp.RawData = buf.Bytes()
}

Example #3

File: scsi.go Project: kurin/tgt

// Send sends a message to the initiator on the appropriate connection.
func (s *Session) Send(m *packet.Message) error {
	m.ISID = s.isid
	m.TSIH = s.tsih
	return s.conn.Send(m)
}
