java.lang.Object

org.jscsi.target.connection.stage.TargetStage

org.jscsi.target.connection.stage.fullfeature.TargetFullFeatureStage

org.jscsi.target.connection.stage.fullfeature.UnsupportedOpCodeStage

public class UnsupportedOpCodeStage
extends TargetFullFeatureStage

Unlike the other subclasses of TargetFullFeatureStage, this class is not associated with a single ScsiOperationCode. All SCSI Command PDUs containing a SCSI OpCode not supported by the jSCSI Target (i.e. without a dedicated FullFeatureStage to process them) shall be passed to the execute(ProtocolDataUnit) method of this class, which will dispatch a standard SCSI Response PDU stating that the given ScsiOperationCode is not supported by this target.

Description copied from class: TargetStage

Starts the stage. This method contains the operational logic required for the receiving, processing and sending of PDUs which is needed to successfully complete the represented iSCSI stage.

Specified by:

execute in class TargetStage

Parameters:

pdu - the first ProtocolDataUnit to be processed in the stage

Throws:

IOException - if the connection was closed unexpectedly

InterruptedException

InternetSCSIException - if a PDU has violated the iSCSI standard

DigestException - if a digest error was detected

SettingsException - if the program has attempted to access a value from settings which has not been negotiated and which does not have a default value
