21.2 Field Definitions

Byte 01, Bit 4 - PF (Page Format)

The Page Format bit specifies the format of the parameter list for the

SEND DIAGNOSTIC command. The CTS does not support any

pages, so the valid value for this field is 0.

Byte 01, Bits 2 through 0 - SelfTest, DevOfL, UntOfL

The SelfTest, DevOfL (Device Offline), and UntOfL (Unit Offline) bits

are used together to determine the test to be performed and the data

to be returned to the initiator. Refer to Table 21-1 for the valid

combinations of these three bits.

Bytes 03 and 04 - Parameter List Length

The Parameter List Length field is used only when the MD bit (byte

05,

bit 7) is 1. If the MD bit is 0, the Parameter List Length field must be

set to 0000.

As shown in Table 21-1, if the MD bit is 1 and the SelfTest, DevOfL,

and UntOfL bits are set to 000, the Parameter List Length field

specifies the starting address for the memory dump. Valid values for

the memory dump starting address are 0000h to 97FFh.

Byte 05, Bit 7 - MD (Memory Dump)

This bit indicates if a processor memory dump is requested, as

follows:

0 – Memory dump not requested.

1 – Memory dump requested.

If the MD bit is 1, the SelfTest, DevOfL, and UntOfL bits must be 000.

Note: If the MD bit is 1 and the SelfTest, DevOfL, and UntOfL bits

are not 000, the SEND DIAGNOSTIC command is rejected

with Check Condition status. The sense key is set to Illegal

Request (5h), and the ASC and ASCQ fields are set to 24h and

00h.

Byte 05, Bit 6 - VU (Vendor Unique)

There is no vendor unique definition for this bit.
