Description / Abstract:

This standard defines the model and command set extensions to facilitate operation of zoned block devices.

The clauses in this standard, implemented in conjunction with the applicable clauses of SPC-5 and SBC-4, specify the standard command set for zoned block devices.

The objectives of this standard are to:

a) permit an application client to communicate over a SCSI service delivery subsystem (see SAM-5) with a logical unit that indicates support for:

A) the zoned block device type in the PERIPHERAL DEVICE TYPE field of its standard INQUIRY data (see SPC-5); or

B) the host aware zoned block device model by setting ZONED field to 01b in the Block Device Characteristics VPD page (see SBC-4);


b) define commands and parameters unique to zoned block devices.
