Appliance fails to join because of slow network switch negotiation
DPM Appliance fails to join another appliance, and the following error shows in log file /opt/appliance/logs/rkma-system.log during join operation:

Resolution
This issue has been fixed in the next release DPM Appliance 3.2 (not released as of writing this article).
As a workaround, for DPM Appliance 3.1.2, update the script /opt/rsa/setup/sh/copy_functions.sh (as shown in red in the following excerpt) to add "ping -c 30" [this will generate 30 ping requests ensuring that the switch receives enough packets to generate its routing table] BEFORE joining operation:

function copyDummyFileFromRemoteServer()
{
username=quser
password=$2
remoteServer=$1
file=/version.txt
copy_dir=/opt/rsa/setup/work
        mkdir -p /opt/rsa/setup/work
        rm -f /opt/rsa/setup/work/version.txt
        rm -f /root/.ssh/known_hosts
        ### KMA-2623 ###
        echo "Pinging host $remoteServer for 30 counts to allow slow switch port negotiation to occur"
        ping -c30 $remoteServer
        ################
        echo "Copying file $file from $remoteServer... "
        COPY_STATUS=`python /opt/rsa/setup/py/GetFileFromRemoteServerNew.py $username $password $remoteServer $file $copy_dir`
        retval=$?
        if [ $retval != 0 ]
        then
                echo "Copy ... Failed.$COPY_STATUS"
                return $retval
        else
                if [ ! -f /opt/rsa/setup/work/version.txt ]; then
                        echo "Could not copy the file"
                        return 1
                fi
                echo "Copy Done"
                return 0
        fi
}
