Executing a Diagnostic Session
4.3 EXECUTING THE SESSION
You now know that you want to execute an interactive session that includes all three disk test categories and that has the following parameters:
• Target device - OS02
• Device state - ON for the nonextended disk tests and the extended read only disk tests, DIAG for the extended write disk tests
• Control terminal - ST01
• Tests - nonextended disk te&ts and extended read only disk tests when disk drive is in the ON state, extended write disk tests when disk drive is in the OIAG state

• Termination mode - one pass through all tests (default)
• Priority level - 3 (default)
• Command log file - volumename.DSKBATCH (batch input file)
NOTE
For the first part of the session, you will execute the nonextended disk tests and the extended read only disk tests, since both groups of tests require the target disk to be installed (by the IV command) and in the online (ON) state.
In the second and final part of the session, you will execute the extended write disk tests. At that time you will perform an Unload Volume (UV) command and then change the target disk to the diag-nostic (DIAG) state.
You are now ready to execute your diagnostic session by using the following instructions. All instructions are numbered and the terminal's responses are preceded by an arrow ("'). The word enter is used to indicate the action of typing in the response to a prompt and pressing the Return
key. ~
