3718.0. "ATL/TL822 almost works but...." by ACISS2::STOUGHTON () Wed Apr 09 1997 17:44

    Hi,
    
     I have a customer that is using an alpha 2100 with an ATL 2640 running
    Dec unix and NSR/Legato.
    
    Please see note 3434 for more configuration information/history.
    
    The system replaced a Sun box, and is working well. The issue that I
    have now is that if you issue a pick tape from the IOD
    command, the software will timeout waiting for the cartridge to be
    placed into the IOD.
    
     The unit never energizes the selinoid to allow the door to open. (no
    green light). If the door has been "forced" open and the command given
    it works ok. Placing a tape into the IOD output bin works fine.
    
    A laptop running the ATL diagnostics (that came with a tl822) runs the
    IOD as well as the tape drive without error.
    
     This is a 6 tape system. microcode is 4 and the model is 6200229.
    Diagnostics used is ATL part number 6207311-11 version 3.03. 
    
     Thanks in advance

	You need something to send a Ready Inport command to get the library to get it to turn on the button. Networker may have something, though it could be under documented. mcutil that is part of the CLC kit may have an option as well. Finally V1.1 of MRU has the "ready" command and it may work in the bare ATL version of the library. Our most recent firmware for the TL820 family versions of the library has an option to turn the button on all the time. You might see if ATL has merged this feature back into their own firmware stream.

	You don't state which version of NetWorker is in use so I can't give an exact answer. We have modified NetWorker to handle the IOD enable for the "DEC TL820". If the deivce is reporting as an "ACL 2640" our fix will not work. NetWorker 4.2a has code for the ATL to enable the input and have the operator press return when the tape is in the port. This could only work if they selected "ATL/Odetics SCSI". Since we don't support this device this has not been tested. Our libraries have a new firmware version (MUSL) that allows the port to be permantly enabled. Your customer may need to check with Odetics to see if they have the same feature available.

	And if you want to know about other NetWorker topics of interest, the NetWorker notes conference is now DECWET::NETWORKER

	Sorry I didn't have the version of Legato at the time of this note. DECunix is 4.0b and NSR is 4.2b. I have also given this location to the guy that lives with this device. He can fill in the blanks I miss as he knows the software. Hi Brian!! Thanks again Gregg
