Question 16

DTM legacy applications (logic for commands that were never ported into standard MfgCmds) are mostly used in ______ due to the lack of “command queuing” for MfgCmd code.

Answer 16

“Performance Testing”

Question 17

SRST is run at what temperature?

Answer 17

Hot

Question 18

It was called “Self-Run Selftest” operation because almost all of the test logic would be contained and run on ____, when before it was run by ___. This eventually became the basis for all test processes, including function test.

Then, in CCB, SRST applications became MfgCmds, and the old SRST code became known as DTM, though the hot temp process maintained the name “SRST.”

Answer 18

the drive’s own processor, tester code

Question 19

CCB architecture introduced a new layer of test firmware known as ____. Functionality that had been SRST applications became ____.

Answer 19

MfgCmd code,

individual MfgCmds

Question 20

The easiest way to adjust DTM sequence and settings is using the ___ tool, a Niagara extension.

Answer 20

Atlas

Question 21

In CCB7, DTM code and data were separated into two different “code bases” and versioned separately. DTM data was given the name “Hercules” and DTM code given the code name “Argo”.

In CCB8, changes to firmware architecture required that DTM code be compiled regularly against new IPFW. For this reason Argo DTM was recombined with Hercules. DTM code (formerly Argo), was moved inside of the ______.

In CCB9, much of the DTM logic will be move to a host controlled process and on-drive DTM logic will be greatly simplified.

Answer 21

MfgCmd code repository

Question 22

____ (also sometimes called ____) are used to conditionally enable steps in the sequence of MfgCmds (as opposed to steps beings statically enabled for all drives).

Let’s say you only need to run a particular test on SAS drives that have internal HGST heads. You can use the ____ head=”HGST” and intf=”SAS” so that only drives where those two conditions are true will run the step.

In CCB8 the most common ___ used is “RECT” or recording type, allowing us to have a bit of a different sequence for the CMR, SMR, and DHSMR (XMR) variants of Leo-C.

Answer 22

Modifiers,
selectors,
(selectors, modifiers)

Question 23

Every Manufacturing test reports one or more 4-character _____. “0000” means that the test successfully passed with no errors. They can originate from several places. DTM reports them for tests that don’t meet specifications and for tests that result in a non-zero MUEC from the MfgCmd code.

Answer 23

failure codes

Question 24

In the Status Block (MCSB) tab in the Atlas tool, you can give _________ for any MCSB output associated with a command. Speccing “ManufacturingCommandUec” (as the parameter) to surface error codes from MfgCmd code is very common and happens in almost all commands.

When the fatal checkbox is checked that spec will immediately cause the drive to end execution as soon as the failure is generated. Non-fatal specs will continue through the sequence and just report the failure at the end of the process.

Answer 24

minimum and maximum spec values

Question 25

In the Atlas tool, if you scroll to the far right of either the MCCB or MCSB tab you find the “magic wand” _____ button for every entry in the list. ____ can be applied to each line of MCCB settings or MCSB specs. The dialog for settings and specs is exactly the same as the one for sequences above.

____ work very similarly to how they work in sequences, where they bring some “smarts” and allow for some dynamic settings and specs where you can do things like “set a different command option for SMR vs CMR drives” or “apply a different spec to HGST heads than to SAE heads”.

Answer 25

modifier(s) (x3)

Question 26

Running MfgTest on Bench:

(May 2018) Since CCB manufacturing tests are run with a system known as “self-run selftest” it is easy to execute a MfgTest from any bench Niagara setup that very closely approximates what the test will be like on dedicated tester hardware. Starting with CCB7, these tests are executed through the HerculesTCL script (often referred to as hercules.tcl, HerculesTools, HercTools, and DTM TCL), available as an extension in Niagara.

At the end, Hecules TCL will save a _____ that can be opened in ____. It can be used to view your data or debug a Mfg failure.
