Tks Salvatore...

Meanwhile gheppy I am using this rather ugly fix which works fine for my testing purposes (stopping entire cluster between times I get to work on it) - just make sure yu shutdown the Slave first and then the Master and on restarting: start the Master first then the slave. Otherwise the Slave will think the Master is dead and HA failover will kick in...

On both machines:

Turn off the sysV init startups:
chkconfig iscsi-ha-watchdog off
chkconfig iscsi-ha off

Then create a bash script to start iscsi-ha with a delay:
nano /usr/bin/hastart.sh

contents:
#!/bin/bash
#chill for a couple of minutes - what's the rush?!
sleep 120
service iscsi-ha start

Make the script executable
chmod +x  /usr/bin/hastart.sh

create a systemd unit file to run the script on startup:
nano /etc/systemd/system/hastart.service

contents:
[Unit]
Description=wait b4 starting iscsi-ha service
[Service]
ExecStart=/usr/bin/hastart.sh
[Install]
WantedBy=multi-user.target

Set it to start on boot:
systemctl enable hastart.service

This has worked thru several shutdowns and restarts as I intermittently work on this project.
