This field has several meanings depending on which MTU Diagnostic command was

 

 

 

 

issued. For read/write MTU Diagnostics, this field specifies the execution time of the

 

 

 

 

read/write. For path test MTU Diagnostics, this field specifies start position. For

 

 

 

 

Medium Changer MTU Diagnostics, this field specifies a cleaning count (FACL

 

 

 

 

only).

This field has different meanings depending on which MTU Diagnostic command

 

 

 

 

was issued. For the read/write DIAG, this field specifies the stop time of the read/

 

 

 

 

write. For path test MTU Diagnostics, this field specifies the end position.

0-7

 

 

Number of times to execute a MTU diagnostic test.

 

 

 

 

 

A description of each MTU Diagnostic command is provided in Chapter 8.

Selection of MTU diagnostic commands is achieved by entering the MTU Diagnostic Command Code in byte 4, and any associated parameters in bytes 5-21. Bytes 22-25 are generally used to specify the number of times to execute the MTU Diagnostic command.

If an error condition is encountered during MTU Diagnostic command execution, diagnostic result data is generated at that time and no further diagnostic execution occurs.

4-3.28.4 Diagnostic Parameter List (PF=0)

Refer to Chapter 8 for the test descriptions.

To use the Diagnostic Parameter List, the Page Format (PF) bit must be cleared to 0. Data in the Diagnostic Parameter List indicates which tests are to be executed and the number of times each test is to be run (execute count). Use of the Diagnostic Parameter List is very similar to Diagnostic
