As per my knowledge, on an appliance, additional cards are used to extend connectivity to additional network. Customer was really enforcing to have network redundancy between the 2 cards. I then took opportunity for some tests. In this post, I would like to share my experience on these tests and how to properly configure network card extension on an ODA.<\/p>\n<p><!--more--><\/p>\n<h3>Introduction<\/h3>\n<p>On an appliance, we can use RJ45 or optical fiber connectivity. On ODA X8 family, optical fiber cards have got 2 ports and RJ45 cards 4 ports. First card is installed in PCIe slot 7.<br \/>\nOn ODA X8-2S 2 additional cards can be installed in slot 8 and slot 10.<br \/>\nOn ODA X8-2M 2 additional cards can be installed in slot 2 and slot 10.<br \/>\nThe only requirement is that all cards from the same server must be from the same type. You can not mix RJ45 and optical fiber on the same ODA.<\/p>\n<p>In my case, as I have got 2 optical fiber network cards, my first card will have p7p1 and p7p2 ports configured (btbond1) and my second card will have p2p1 and p2p2 ports configured (btbond3).<\/p>\n<p>ODA bonding is configured to use active-backup mode with no LACP.<\/p>\n<h3>Is bonding redundancy possible on an ODA?<\/h3>\n<h4>Configuring bonding across network card<\/h4>\n<p>My first experience was to edit ifcfg-p7p2 and ifcfg-p2p1 linux network script configuration file, and assign p7p2 to btbond3 and p2p1 to btbond1. Of course, this was just for an experience and to keep such solution as definitive would mean to rollback this non supported configuration before any ODA patching. I really do not encourage to do so. \ud83d\ude09<br \/>\nAnyway, my experience was not successful as after a reboot, both files were restored in their original configuration.<\/p>\n<h4>Configuring a different IP address for each network on each card<\/h4>\n<p>I then tried to configure both cards with 2 IP addresses from the 2 networks as below :<br \/>\nBond 1 IP 10.3.1.20 (no VLAN)<br \/>\nBond 3 IP 10.3.1.21 (VLAN 723)<br \/>\nBond 1 IP 192.20.30.2 (no VLAN)<br \/>\nBond 3 IP 192.20.30.3 (VLAN 723)<\/p>\n<p>The configuration could be successfully applied and everything was configured as expected :<\/p>\n<p><code>[root@ODA01 network-scripts]# <strong>ip addr show btbond1<\/strong><br \/>\n8: btbond1:  mtu 1500 qdisc noqueue state UP<br \/>\nlink\/ether b0:26:28:72:0e:d0 brd ff:ff:ff:ff:ff:ff<br \/>\ninet 10.3.1.20\/24 brd 10.3.1.255 scope global btbond1<br \/>\nvalid_lft forever preferred_lft forever<br \/>\n&nbsp;<br \/>\n[root@ODA01 network-scripts]# <strong>ip addr show btbond1.723<\/strong><br \/>\n17: btbond1.723@btbond1:  mtu 1500 qdisc noqueue state UP<br \/>\nlink\/ether b0:26:28:72:0e:d0 brd ff:ff:ff:ff:ff:ff<br \/>\ninet 192.20.30.2\/29 brd 192.20.30.7 scope global btbond1.723<br \/>\nvalid_lft forever preferred_lft forever<br \/>\n&nbsp;<br \/>\n[root@ODA01 network-scripts]# <strong>ip addr show btbond3<\/strong><br \/>\n9: btbond3:  mtu 1500 qdisc noqueue state UP<br \/>\nlink\/ether b0:26:28:7c:8a:50 brd ff:ff:ff:ff:ff:ff<br \/>\ninet 10.3.1.21\/24 brd 10.3.1.255 scope global btbond3<br \/>\nvalid_lft forever preferred_lft forever<br \/>\n&nbsp;<br \/>\n[root@ODA01 network-scripts]# <strong>ip addr show btbond3.723<\/strong><br \/>\n18: btbond3.723@btbond3:  mtu 1500 qdisc noqueue state UP<br \/>\nlink\/ether b0:26:28:7c:8a:50 brd ff:ff:ff:ff:ff:ff<br \/>\ninet 192.20.30.3\/29 brd 192.20.30.7 scope global btbond3.723<br \/>\nvalid_lft forever preferred_lft forever<\/code><\/p>\n<p>But, unfortunately, such a configuration is not working successfully as some packets got lost by the kernel when routing between both bonding.<\/p>\n<h4>So, what&#8217;s next?<\/h4>\n<p>Opening a SR by Oracle I could get the confirmation that network cards redundancy and physical failover between cards in case of total loss of a network card is not compatible and not possible. Appliance does not support it.<\/p>\n<h3>Configure an ODA with 2 network cards<\/h3>\n<p>In this part I would like to share how to configure additional network cards on an ODA. Below would be the IP Addresses to use :<br \/>\nBond 1 IP 10.3.1.20 (no VLAN) for application and backup network<br \/>\nBond 3 IP 192.20.30.2 (VLAN 723) for redundancy network<\/p>\n<h4>btbond1 configuration<\/h4>\n<p>btbond1 configuration has been done through configure-firstnet after reimaging the ODA :<\/p>\n<p><a

Today, there is no solution to cover a faulty network card or a card loss. Having bonding crossing several network cards is not possible.
