    Drives are not always DOWN'ed because of a tape drive error/failure. Bad media, HBA error, even driver issue can cause a drive to be DOWN'ed.
    Here we need the 'second hand' information logged in OS and NBU logs...

    Please do not forget to add VERBOSE entry to vm.conf on all media servers and restart NBU Device Manager (ltid). 
    Windows: <install-path>\veritas\volmgr\vm.conf
    Unix/Linux: /usr/open/volmgr/vm.conf
    This will increase Media Manager logging to system logs. 
    In Windows, exact reason for drives being DOWN'ed will be logged in Application log.
    Unix/Linux will log to syslog, e.g. /var/log/messages on Linux, /var/adm/messages on Solaris.
