Solution 2013605.1 : ODA : Deploying oda_base in VM Installation IP Address of Eth1 Gets Overwritten with the Same IP Address as Eth0

Applies to:

Oracle Database Appliance Software - Version 12.1.2.2 to 12.1.2.2 [Release 12.1]
Oracle Database Appliance X5-2 - Version All Versions to All Versions [Release All Releases]
Information in this document applies to any platform.

Symptoms

During the deployment of ODA_BASE in a virtualized ODA with 12.1.2.2 image, IP address of Eth1 overwritten with the same Ip Address as Eth0 in the SetupNetwork step.

The ODAVP deployment configures both eth0 and eth1 with the same public ip address although different ip addresses were specified for eth0 and eth1 interface.

e.g.

ipconfig output will be like :

eth0: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc pfifo_fast qlen 1000
link/ether 00:16:3e:7e:20:15 brd ff:ff:ff:ff:ff:ff
inet 172.28.220.64/24 brd 172.28.220.255 scope global eth0 <<<----- IP address
inet6 fe80::216:3eff:fe7e:2015/64 scope link
valid_lft forever preferred_lft forever

eth1: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc pfifo_fast qlen 1000
link/ether 00:16:3e:75:51:98 brd ff:ff:ff:ff:ff:ff
inet 172.28.220.64/24 brd 172.28.220.255 scope global eth1 <<<----same as eth0
inet6 fe80::216:3eff:fe75:5198/64 scope link
valid_lft forever preferred_lft forever

Changes

No change. It's fresh VM installation on 11.2.1.2.2.

Cause

This is due to following bug in deployment script.
Bug 20855614 - LNX64-121-CMT:X5-2,ETH1 GET SAME IP WITH ETH0 DURING DEPLOYING RAC/GI

Solution

As a workaround , once the deployment is completed manually edit the "/etc/sysconfig/network-scripts/ifcfg-eth1" and correct the IP address.

This bug is fixed in 12.1.2.3 image version and it is available now on MOS.

So recommendation is as this is a new installation either upgrade to 12.1.2.3 or re-image the system with 12.1.2.3. image and run the deployment procedure.
