- Code Set specifies the data type for the identifier field. Code Set = 1 indicates binary data
- PIV (Protocol Identifier Valid) set to one indicates that the Protocol Identifier field contains a valid value.
- Association specifies the entity with which the Identifier field is associated: 1h for Target or Relative Port.
- Identifier Type specifies the format and assignment authority for the identifier: 3h indicates NAA format of the
WWID for Target Port.
- Identifier fields contain the actual Identifier Descriptor.
- The Target Port Identifiers are defined in the NAA IEE WWID format where:
World Wide ID is a 64-bit unique identification for each drive. The format is: 5000CCAh
xxxh n yyb where xxx is the 12-bit block assignment defined for each model and manufacturing site, n is the
22-bit drive unique serial number, and yy is the 2-bit port/node ID

- Qualifier field is set to zero to indicate that the LUN specified in the Command Block is currently supported.
- Peripheral Device Type is set to zero to indicate that the device is Direct Access.
- Page Code is set to the value of the page code field in the CDB.
- Page Length is set to 14, and this field specifies the length of the following page data.
- If set to one, a power condition support bit (STANDBY_Y, STANDBY_Z, IDLE_C, IDLE_B, IDLE_A) indicates
that the associated power condition may be entered with START STOP UNIT command and the associated
power condition may be entered with a power condition timer if the timer is supported and enabled.
- The recovery time fields indicate the time, in one millisecond increments, that the logical unit takes to
transition from the associated power condition to the active power condition. This time does not include the
processing time for the command that caused this transition to occur. A value of zero indicates that the recovery
time is not specified. A value of FFFFh indicates that the recovery time is more than 65.534 seconds.
