3.8.4 FORMAT UNIT command A device which supports Thin Provisioning will be capable of performing a SCSI FORMAT UNIT command which allocates Logical Blocks Addresses that are not linked to Physical Block Locations. A FORMAT command will cause all LBAs to become unmapped. 3.8.5 Protection Information (PI) and Security (SED) The requirements in this section apply to any device which supports LBA unmapping. In SCSI devices, umapped LBAs are defined as part of the Thin Provisioning model. Support of the Thin Provisioning model is indicated by the LBPME bit having a value of '1' in the READ CAPACITY (16) parameter data. When a region of LBA's are erased via cryptographic erase, as part of the erase, the drive shall unmap those LBAs. If the host attempts to access an unmapped or trimmed LBA, the drive shall return scrambled data. For a given LBA, the data shall be identical from access to access, until that LBA is either updated with actual data from the host or that LBA is cryptographically erased. The drive shall report a value of '0' in the LBPRZ field returned in the READ CAPACITY (16) parameter data. If the host attempts to access an unmapped LBA on a drive that has been formatted with Protection Information (PI), the drive shall return scrambled PI data for that LBA. Depending on the value of the RDPROTECT field in the data-access command CDB, this may result in the drive returning a standard PI error to the host. If the host reduces the addressable capacity of the drive via a MODE SELECT command, the drive shall unmap or trim any LBA within the inaccessible region of the device. Additionally, an UNMAP command is not permitted on a locked band.

3.8.4

FORMAT UNIT command

A device which supports Thin Provisioning will be capable of performing a SCSI FORMAT UNIT command which allocates

Logical Blocks Addresses that are not linked to Physical Block Locations. A FORMAT command will cause all LBAs to

become unmapped.

3.8.5

Protection Information (PI) and Security (SED)

The requirements in this section apply to any device which supports LBA unmapping.

In SCSI devices, umapped LBAs are defined as part of the Thin Provisioning model. Support of the Thin Provisioning model

is indicated by the LBPME bit having a value of '1' in the READ CAPACITY (16) parameter data.

When a region of LBA's are erased via cryptographic erase, as part of the erase, the drive shall unmap those LBAs.

If the host attempts to access an unmapped or trimmed LBA, the drive shall return scrambled data. For a given LBA, the data

shall be identical from access to access, until that LBA is either updated with actual data from the host or that LBA is

cryptographically erased. The drive shall report a value of '0' in the LBPRZ field returned in the READ CAPACITY (16)

parameter data.

If the host attempts to access an unmapped LBA on a drive that has been formatted with Protection Information (PI), the

drive shall return scrambled PI data for that LBA. Depending on the value of the RDPROTECT field in the data-access

command CDB, this may result in the drive returning a standard PI error to the host.

If the host reduces the addressable capacity of the drive via a MODE SELECT command, the drive shall unmap or trim any

LBA within the inaccessible region of the device.

Additionally, an UNMAP command is not permitted on a locked band.
