Chapter 5 Initiator Mode Pass-through Commands

Initiator Pass-through Status Block Format Page 5 - 17

Selectable Sense Bytes

You also have the option to select which (up to 16) of the 256 possible Sense

bytes be returned in the Status Block and in what order they should appear.

• The Unit Options command allows you to choose 8 selectable Sense

Bytes.

• The Extended Unit Options command allows you to choose 16 selectable

Sense Bytes. You will receive multiple Status Blocks.

You can specify Selectable Sense Bytes by placing a zero in the Sense Count

field and filling each of the Selected Sense fields with the Sense Byte number

you wished returned in that field.

For example, the Sense Bytes fields of a Status Block could return the following

Sense Bytes in the following order if the Extended Unit Options command had

been used.

Status Block #1 contains the first eight bytes with the Info Bytes arranged from

LSB to MSB, and Status Block #2 returns Sense Bytes that are selected from

among the other 248 Sense Bytes, based on information in the vendor-supplied

peripheral documentation.

See Chapter 7 for more information about the Unit Options and Extended Unit

Options commands and how to set-up the Status Block Sense bytes the way

you wish.
