    Good Morning;

    RE: server with an AIC SCSI Host Adapter, on boot goes thru
    Channel A ok, then goes to Channel B, makes start-up request of Iomega Jaz IGB, and FAILS...actual chanel B target Id #4 says...."Unexpected scsi command failure ", followed by a bunch of stats (locations). Hardware mgr indicated the Jaz device checks out ok, (Jaz only dvice on B channel but the channel itself indicates its functional)-

    Anybody have a suggestion where to begin to look for source of problem? doesnt appear channel corrupt just the jaz device itself, more likely, its scsi channel B settings- any troubleshooting assit would be genuinely apprteciated!

    regards
    Webz

    Take out the Jaz drive and see if the SCSI controller initializes correctly.

    would this indicate that the Jaz Iomega is defective?

    Hi Again;

    had originally made an inquiry re a server's "B Channel" that attempted ..."a start-up request" of an Iomega Jaz. The start-up request,according to eror message, "failed"- but the server continued its boot-up sequence and started nevertheless.

    My question pertains to "WHY THE JAZ FAILED". It was suggested I remove the Jaz from channel B, which I did. The server bypassed channel b because the Jaz was the only device on that channel. Channel A booted fine and the server started normally.

    I'm trying to figure out WHAT I PROVED BY REMOVING THE JAZ?
    IS IT A BAD UNIT? And since the boot-up recognized the Jaz, only that it failed its request, wouldnt that indicate that the ribbon cable is ok as well as the b channel of the SCSI Controler?

    any clarification woud genuinely be appreciated

    rtegard

    the following error message appears on start-up/boot-up...pertains to channel B/SCSI ADAPTER;

    "UNEXPECTED SCSI COMMAND FAILURE"
    ____________________

    * SCSI CDB SENT 03 00 00 00 0E 00 70 00 02 00

    * TARGET: #4

    * HOST ADAPTER STATUS: 02H NO HOST ADAPTER ERROR

    * TARGET STATUS: 02 CHECK CONDITION

    * SENSE KEY: 02 NOT READY

    * SENSE CODE: 3AH

    * SENSE CODE QUALIFY: 00H

    THE RESULT IS THAT THE SCSI ADAPTER, ON CH B, HAS A REMOVABLE DISK DRIVE ON IT. WHEN THE CONTROLLER GOES TO RECOGNIZE IT, IT RETURNS A...."START-UP REQUEST FAILED" RESPONSE BUT THE PC STARTS SUCCESSFULLY ANYWAY-

    ANYBODY CARE TO TAKE A STAB?

    THANKS

    If this problem is important to solve, you will want to give us some background:

    1. Has the drive ever worked properly?
    2. If "yes" then what have you recently changed in your system if anything? New hardware? Installed Iomegaware or other software?
    3. Have you made any adjustments to CMOS or to The "bios" of your SCSI card?
    4. Is the jaz disc any good or has it been damaged? Have you tried starting without a disc?

    Try a different Jaz drive if available.
