Command Specifications c. CDB size This field contains the number of bytes in the CDB for the operation code being queried, and the size of the "CDB Usage Data" field in the return data. d. CDB usage data This field contains information about the CDB for the operation code being queried. The first byte of the "CDB usage data" contains the operation code for the operation being queried. All bytes except the first byte of the "CDB usage data" contains a usage map for bits in the CDB for the operation code being queried. The bits in the "Usage map" have a one-for-one correspondence to the CDB for the operation code being queried. If the device server evaluates a bit as all or part of a field in the CDB for the operation code being queried, the usage map contains a one in the corresponding bit position. If the device server ignores or treats as reserved a bit in the CDB for the operation code being queried, the usage map contains a zero in the corresponding bit position. The usage map bits for a given CDB field all have the same value. Thus, the CDB usage bit map for Inquiry command for a device server that implements command support data but not vital product data is: 12h, 02h, FFh, 00h, FFh, 01h. (7) VPD information When "1" is specified in the "EVPD" bits of the CDB, the VPD information described below is transferred to the INIT by this command.

C141-C010

CDB size

This field contains the number of bytes in the CDB for the operation code being queried, and the size

of the "CDB Usage Data" field in the return data.

d. CDB usage data

This field contains information about the CDB for the operation code being queried.

The first byte

of the "CDB usage data" contains the operation code for the operation being queried.

All bytes

except the first byte of the "CDB usage data" contains a usage map for bits in the CDB for the

operation code being queried.

The bits in the "Usage map" have a one-for-one correspondence to the CDB for the operation code

being queried.

If the device server evaluates a bit as all or part of a field in the CDB for the

operation code being queried, the usage map contains a one in the corresponding bit position. If the

device server ignores or treats as reserved a bit in the CDB for the operation code being queried, the

usage map contains a zero in the corresponding bit position.

The usage map bits for a given CDB

field all have the same value.

Thus, the CDB usage bit map for Inquiry command for a device server that implements command

support data but not vital product data is: 12h, 02h, FFh, 00h, FFh, 01h.

VPD information

When "1" is specified in the "EVPD" bits of the CDB, the VPD information described below is

transferred to the INIT by this command.

The INIT specifies the type of VPD information required in

the "Page code" field of the CDB.

The type of VPD information supported by the IDD and its page code

number are as shown below.

Furthermore, if page codes other than those shown above (VPD information that is not supported by the

IDD) are specified in the CDB, that command is terminated with a CHECK CONDITION status

(ILLEGAL REQUEST [=5] / Invalid field in CBD [=24-00]).

The format and contents of each type of VPD information are shown below.

Page code list

This VPD information reports the page code list of VPD information supported by the IDD.
