Jim, 

This script is becoming outdated because the log messages have changed so 
much, so don't worry about the error messages now.

This will help the LDM start, it's a HP security problem.  Change
check_registered in bin/ldmadmin  from :

sub check_registered {

    $rpcinfo_cmd = "rpcinfo -t localhost 300029";
    `$rpcinfo_cmd 5 > /dev/null 2>&1`;
    if($?) {
        `$rpcinfo_cmd 4 > /dev/null 2>&1`;
        if($?) {
             return 1;
        }
    }
    return 0;
}


to

sub check_registered {

    $rpcinfo_cmd = "rpcinfo -p | grep  300029";
    `$rpcinfo_cmd  > /dev/null 2>&1`;
    if($?) {
             return 1;
    }
    return 0;
}

Also since your disk became full it's possible that you ldm queue is
corrupted.  I would ldmadmin stop/delqueue/mkqueue/start just to make sure
it's ok.  One can check if data is arriving by ldmadmin watch.
