You should now be able to run the following command on the command line of the HOST A server:

iscsiadm --m session --op show

You should see something like the following from the above command.

#tcp: [1] 10.10.10.3:3260,1 iqn.2000-01.com.synology:SynNAStestA.oVirtEngine.2776b78dce (non-flash)

For VNC Connections run this

hosted-engine --add-console-password

 

#To enable libvirt command line calls run the following command. If you ever use libvirt commands you can use the username/password below to access them.

saslpasswd2 -a libvirt myfavoriteusername

 

If you SSH into the  oVirtEngineVM as root, run the following config commands:

#this sets up VNC as the default console type and will allow console to run in web browser
engine-config -g ClientModeVncDefault
engine-config -s ClientModeVncDefault=NoVnc
engine-config -g ClientModeVncDefault

UPDATE FENCING OPTIONS on ENGINE

engine-config -s vdsConnectionTimeout=2
engine-config -s vdsRetries=0

 

Setup engine backup

vi /root/backup_my_engine.sh
###
#!/bin/bash

#required for cronjob
DIR="$( cd "$( dirname "${BASH_SOURCE[0]}" )" && pwd )"
cd $DIR

export TERM=xterm

BUDATE=`date "+%Y-%m-%d-%H%M%S"`

engine-backup --mode=backup --file="engine-backup${BUDATE}.bak" --log="engine-backup${BUDATE}.log"

cp /root/engine-backup${BUDATE}* /mnt/backups/engine/
rm /root/engine-backup${BUDATE}*
