SCSI Block Commands.

This file contains definitions of some of the commands found in the SCSI SBC-2 standard.

Note that the SBC specification depends on several commands defined by the SCSI Primary Commands (SPC) standard. Each version of the SBC standard is meant to be used in conjunction with a specific version of the SPC standard, as follows:

• SBC depends on SPC
• SBC-2 depends on SPC-3
• SBC-3 depends on SPC-4
