transferred. The ATTO FibreBridge will transfer the complete buffer or allocation length bytes, whichever
is less.
The Buffer Offset field contains the byte offset within the specified buffer from which data will be
transferred. If the specified buffer offset is invalid, ATTO FibreBridge will return a CHECK CONDITION
status with a sense key of ILLEGAL REQUEST and additional sense code of INVALID FIELD IN CDB.
If an unsupported Buffer ID code is selected, the ATTO FibreBridge will return a CHECK CONDITION
status with a sense key of ILLEGAL REQUEST and additional sense code of INVALID FIELD IN CDB.
Read/Write Buffer buffer id descriptions and usage are provided in the ATTO Technology ATTO
FibreBridge NVRAM Specification. ATTO Technology provides the ATTO BridgeTools GUI-based utility
to facilitate managing the NVRAM parameters.
