  1. NBU 3.4.1/SAN/Win2000 - SCSI-Fibre mappings - job fails


    I have a SAN implementation with a SUN master and Win200 media servers. The
    backups , once working fine, are now not running through the SAN.
    A tape gets loaded, but hangs before writing any data. It appears that the
    server no longer finds the devices (drives) in the library. I've also noticed
    that the serial numbers of the drives, which are used for initial discovery
    and configuration, are no longer present in the configuration dialog boxes.
    When they were, the backups ran well.
    Is there any way to "reinitialize" the OS, without rebooting the Media servers
    (they are production servers), so that the devices are again recognized?
    I've tried rebooting the library/master/switch, rescanning for devices using
    the Win200 device manager, resetting the (Emulex) HBA, starting/stopping
    NBU services, and reinstalling the patch and Veritas tape drivers.
    Thanks in advance!
    Jeff

    We are also experiencing the same problem, did anyone every figure out what

    Is your bridge configured to Veritas' recommended "Autoconfigure"? We found
    this doesn't work with our SAN. Check your Logical Fibre Channel Lun Mapping
    information in the bridge. Set it to "Indexed" not Auto.

    I have seen this with our backups as well. We found that the drives were
    scanned in the wrong order. I manually changed the drives (Swapped them) in
    media manager and it works fine. This only applies if you have multiple
    drives on your media server.

    Hope this helps.
    Please repsond with the results or if you need more info.

    Actually the final fix we came up with was upgrading the frimware on the HP
    bridges and this solved that issue. Thanks for your input.
