Summary
Member Variables
| Name | Description |
|---|---|
| uint8_t senseData [SCSIPERIPHERAL_MAX_SENSE_DATA_LEN] | Sense data, that is, information returned by the SCSI device to the host to report the device status, error information, and diagnosis information. |
| ScsiPeripheral_Status status | Status when the call is complete, for example, Good or Busy. |
| uint8_t maskedStatus | Masked status, which is used in SCSI Generic (SG) interfaces of Linux to store the processed SCSI status for easy access by applications. |
| uint8_t msgStatus | Message status. |
| uint8_t sbLenWr | Number of bytes that are actually written to the sense buffer. |
| uint16_t hostStatus | Host adapter status, for example, success (0x00), connection failure (0x01), busy bus (0x02), or timeout (0x03). |
| uint16_t driverStatus | Driver status, for example, success (0x00) or busy device or resource (0x01). |
| int32_t resId | Length deviation of the actually transmitted data, that is, the number of bytes that are not transmitted. |
| uint32_t duration | Command execution duration, in ms. |
