eth0.z is the name of the NIC configuration file (/etc/sysconfig/network-scripts/ifcfg_eth0.z)

dedicated to IP address in VLAN z (isolation for example).

(eth0.y, eth0.z) with the following content:

case "$2" in

start)

echo -n "Mounting $1"

/sbin/ifup $1

echo "."

;;

stop)

echo -n "Unmounting $1"

/sbin/ifdown $1

echo "."

;;

echo "Usage: $0 {start|stop}"

exit 1

;;

esac

and make it executable:

# chmod 755 /etc/ha.d/resource.d/IfUp

Create /etc/ha.d/authkeys with the following content:

auth 1

1 sha1 10b245aa92161294df5126abc5b3b71d

and change its rights like this:

# chmod 600 /etc/ha.d/authkeys

Create /etc/logd.cf with the following content:

debugfile /var/log/ha-debug

logfile /var/log/ha-log

logfacility daemon
