Solution 1181413.1 : T10000 - 1.46.x09 Diagnostic Bug - Can't Run Offline Diags Load-Unload Test While Drive is in a Library

Symptoms

When attempting to run the load/unload test it fails as follows:

8:10 PM Aug 17, 2010 - START C:\Program Files\VOP
1.0.15\diags\Load_Unload_Test.117 Test

Install a DUMP tape for Load_Unload_Test

8:11 PM Aug 17, 2010 - Tape Cartridge is LOADED

DC_BUFFER_TEST PASSED

DUMP tape was successfully loaded

UNLOADING
8:12 PM Aug 17, 2010 - Tape Cartridge is UNLOADED
8:12 PM Aug 17, 2010 - Tape Cartridge is UNLOADED

LOADING
EPT_DIAG_FAILED_LOAD

I then loaded 1.44.210 on the drive and re-ran the test:

8:19 PM Aug 17, 2010 - START C:\Program Files\VOP
1.0.15\diags\Load_Unload_Test.117 Test

Install a DUMP tape for Load_Unload_Test

DC_BUFFER_TEST PASSED
DUMP tape was successfully loaded

LOAD_UNLOAD_TEST ran for 3 minutes and 15 seconds

FDE_DONE: Load_Unload_Test.tcf test has completed

8:22 PM Aug 17, 2010 - END C:\Program Files\VOP
1.0.15\diags\Load_Unload_Test.117 Test

I then reloaded 1.46.209 on the drive and ran the test again:

8:27 PM Aug 17, 2010 - START C:\Program Files\VOP
1.0.15\diags\Load_Unload_Test.117 Test

Install a DUMP tape for Load_Unload_Test

8:27 PM Aug 17, 2010 - Tape Cartridge is LOADED

DC_BUFFER_TEST PASSED

DUMP tape was successfully loaded

UNLOADING
8:28 PM Aug 17, 2010 - Tape Cartridge is UNLOADED
8:28 PM Aug 17, 2010 - Tape Cartridge is UNLOADED

LOADING
EPT_DIAG_FAILED_LOAD

The drive just sits there thinking it's running the test. (If I press "Done" it says it's still running diags) If I interrupt the test by removing the tape from the elevator and reinserting it I get the following:

8:30 PM Aug 17, 2010 - Tape Cartridge is EJECTED
LOAD failed with FSC: #000032B8

8:30 PM Aug 17, 2010 - Tape Cartridge is LOADED

UNLOADING
8:30 PM Aug 17, 2010 - Tape Cartridge is UNLOADED
8:30 PM Aug 17, 2010 - Tape Cartridge is UNLOADED

LOAD_UNLOAD_TEST ran for 3 minutes and 24 seconds

FDE_DONE: Load_Unload_Test.tcf test has completed

Changes

1.46.109 (T10000A) or 1.46.209 (T10000B) code was installed.

Cause

Starting with 1.46.109/209, you can't run FDE Offline Diags Load-Unload test on a drive that's in a library tray AND has the TTI cable (P40) connected to the drive, EVEN if the drive is on a bench.

Solution

This means that for SL8500 drives in a tray AND on a bench, you'll have to remove the top lid and disconnect the TTI cable/P40 (for L700 and SL3000 just pull the TTI/P40 on the back of the drive).
Apparently there was an issue with t10k drives and 1.44 110/210 where sometimes drives were not being 'seen' by the library after drive ipl, so the 'user' had to force an 'error' on the drive so that the library would 'see' the drive. That fix now means you have to unplug TTi/P40 to run the FDE Offline Diags Load-Unload test on trayed drives running 1.46.109/209.

Apr 12 2012 update: Engineering has agreed to change the code to allow running of this diagnostic without having to unplug the TTI cable from the drive. Reference CR 7160658.
