Setting IPMP on Solaris 10 - probe based detection


Based on http://docs.sun.com/app/docs/doc/816-4554/emqra?a=view

Here the actions :
activate ethernet interface
# ifconfig ce0 plumb up
# ifconfig ce1 plumb up

Giving IP Address and IP Multipathing
# ifconfig ce0 10.172.75.3 netmask 255.255.255.0 broadcast + group ipmp1 deprecated -failover up \
addif 10.172.75.2 netmask 255.255.255.0 broadcast + failover up

# ifconfig ce1 10.172.75.4 netmask 255.255.255.0 broadcast + group ipmp1 deprecated -failover up

Now we have 3 IP address, 2 physical ( 10.172.75.3 & 10.172.75.4 ) and 1 virtual ( 10.172.75.2 ).

If this setting keep on when system reboot, check all following conf file.

# more /etc/hosts
127.0.0.1 localhost
10.172.75.2 server01-vip
10.172.75.3 server01-ce0
10.172.75.4 server01-ce1

# more /etc/netmasks
10.172.75.0 255.255.255.0

#more /etc/defaultrouter
10.172.75.1

# more /etc/hostname.ce0
10.172.75.3 netmask 255.255.255.0 broadcast + group ipmp1 deprecated -failover up \
addif 10.172.75.2 netmask 255.255.255.0 broadcast + failover up

# more /etc/hostname.ce1
10.172.75.4 netmask 255.255.255.0 broadcast + group ipmp1 deprecated -failover up
