- Connect eth2 from both nodes to switch 1
- Connect eth3 from both nodes to switch 2
Now you have two paths available
- Enter the IP address of eth2 in the /etc/hosts file
example:
server-priv1 10.10.10.10
- edit the /etc/hostname.eth2 as follows:
server-priv1 netmask + broadcast + group ipmp0 up
- edit the /etc/hostname.eth3 as follows:
group ipmp0 up
Reboot the server
Note: Do not assign IP to the standby interface.
Note: Assuming you are using solaris10
use the following command to test ipmp via CLI
#if_mpadm [-r] [-d] <interface>
- -r -> revert back
- -d -> disable i-e failover

if_mpadm
if_mpadm(1M) System Administration Commands if_mpadm(1M)
NAME
if_mpadm - change operational status of interfaces within a multipathing group
SYNOPSIS
/usr/sbin/if_mpadm -d interface_name
/usr/sbin/if_mpadm -r interface_name
DESCRIPTION
Use the if_mpadm utility to change the operational status of interfaces that are part of an IP multipathing group. If the interface is
operational, you can use if_mpadm -d to detach or off-line the interface. If the interface is off-lined, use if_mpadm -r to revert it to
its original state.
When a network interface is off-lined, all network access fails over to a different interface in the IP multipathing group. Any addresses
that do not failover are brought down. Network access includes unicast, broadcast, and multicast for IPv4 and unicast and multicast for
IPv6. Addresses marked with IFF_NOFAILOVER do not failover. They are marked down. After an interface is off-lined, the system will not use
the interface for any outbound or inbound traffic, and the interface can be safely removed from the system without any loss of network
access.
The if_mpadm utility can be applied only to interfaces that are part of an IP multipathing group.
OPTIONS
The if_mpadm utility supports the following options:
-d interface_name Detach or off-line the interface specified by interface_name.
-r interface_name Reattach or undo the previous detach or off-line operation on the interface specified by interface_name. Unless
the -d option was used to detach or off-line the interface, this option will fail.
EXAMPLES
Example 1: Detaching an Interface
Use the following command to off-line or detach the interface. All network access will failover from hme0 to other interfaces in the same
IP multipathing group. If no other interfaces are in the same group, the operation will fail.
example% if_mpadm -d hme0
Example 2: Reattaching an Off-line Interface
Use the following command to undo the previous operation. Network access will failback to hme0.
example% if_mpdadm -r hme0

DIAGNOSTICS
off-line failed as there is no other functional interface available in the multipathing group for failing over the network access.
This message means that other interfaces in the group are failed over already or the multipathing configuration was not suitable for com-
pleting a failover.
off-line cannot be undone because multipathing configuration is not consistent across all the interfaces in the group.
This message means that some interfaces in the IP multipathing group are not configured consistently with other interfaces in the group,
for example, one of the interfaces in the group does not have an IFF_NOFAILOVER address.
