468.0. "Tlz09's replaces TLZ07 but not on MLS+?" by CHEFS::HOWLETT_T (Avoiding the cracks in the pavement) Tue Apr 01 1997 10:15

    Hi
    
    	Is there any chance the TLZ09 can be made to work with Mls+ 3.1A
    	are there any patches? Its the only tape shipping now

468.1did you try it? if it works, it works :-)SMURF::BATSegui la tua beatitudineTue Apr 01 1997 16:4811
    I just looked at the DIGITAL UNIX V3.2B SPD, and it has TKZ09 but not
    TLZ09.  The first DIGITAL UNIX to have TLZ09 listed is V3.2C.  It's my
    understanding Unix product management try to back-update hardware
    support on older version SPDs, but I could be wrong.
    
    I do not know enough about the tape drives to know what the differences
    are.  If it will run on DIGITAL UNIX V3.2B, it should run on V3.1A
    MLS+.  I'll check with Lee when he gets in tomorrow.
    
    Is there a reason why the customer cannot upgrade to MLS+ V4.0A?
    Ooops, I take that back, I assume it must be SPS.

My understanding is that the tlz09 is a drop-in replacement for
the tlz07.  I haven't actully tried it yet, but I have a couple
that we can try if this is important.

    Well my guess is that V3.2B does not have the cam_data.c updates it
    needs.  You might be able to field upgrade them (just as you would
    customize for a non-DEC device), I don't know.  This will take some
    time to figure out; I'm not sure what the position on this is --
    do you want to add support for TLZ09 to MLS+ V3.1A? If yes, then
    it's probably ECP time, or else this goes to the bottom of the queue...

Note 7831.1             Is TLZ09 really working on DUnix?                 1 of 4

                  -< Check for firmware rev. 0167 (minimum) >-
--------------------------------------------------------------------------------
Does # "scu show edt bus 0 target 4 full" amongst other show the following:

            Product Identification: TLZ09     (C)DEC
           Firmware Revision Level: 0167

firmware upgrade tape partnr. QZ-00LAC-UP  (see stkhlm::magtape 3469.1)



If the firmware is not updated to 0167, you will see the problems you have.
Firmware update tape needs only to be inserted, then it upgrades itself.

(Bus termination could also be an issue.)

468.5is it hardware? (I love to say that as a SW person)SMURF::BATSegui la tua beatitudineTue Jun 03 1997 22:566
    I was wrong.  Lee just put a TLZ09 on a FlamingO (DEC 3000-500) and it
    worked just fine (i.e., no CAM errors) -- successfully tar'd and
    dump/restore'd.
    
    Zo -- he thinks you maybe have a hardware problem.  Or -- what model
    Alpha are you using?
