org.jscsi.target.scsi.cdb.Read6Cdb

This class represents Command Descriptor Blocks for the READ (6) SCSI command.

The READ (6) command requests that the device server read the specified logical block(s) and transfer them to the data-in buffer. Each logical block read includes user data and, if the medium is formatted with protection information enabled, protection information. Each logical block transferred includes user data but does not include protection information.

Although the READ (6) command is limited to addressing up to 2,097,151 logical blocks, this command has been maintained as mandatory since some system initialization routines require that the READ (6) command be used. System initialization routines should migrate from the READ (6) command to the READ (10) command, which is capable of addressing 4,294,947,295 logical blocks, or the READ (16) command, which is capable of addressing 18,446,744,073,709,551,615 logical blocks. @author Andreas Ergenzinger
