Solution 2099905.1 : ODA VM : Ethernet Bridges Won't Start On Boot when there is '-' in interface name

Applies to:

Oracle Database Appliance X4-2 - Version All Versions to All Versions [Release All Releases]
Oracle Database Appliance Software - Version 2.1.0.1 to 12.1.2.5 [Release 2.1 to 12.1]
Information in this document applies to any platform.

Symptoms

VLAN interface is down after Node reboot though configuration of the bridge has ONBOOT parameter is set to YES.

When trying to bring UP the interface with the ifup command it returns:

[root@node1 ~]# ifup infra-backup
Missing config file ifcfg-infra.

following command worked:

[root@node1 ~]# ip link set infra-backup up

Changes

Interface name changed infra-backup.

Cause

The ifcfg-infra-backup is not a valid name for network scripts, need to loose the '-' in the infra-backup or rename it to infra_backup.
This is an expected behavior as mentioned in the <Bug 21822405> : LINK STATUS OF BRIDGE INTERFACE IS DOW

Solution

Steps to rename:

+ Stop bridge

# ifdown infra-backup

+ Rename ifcfg-infra-backup to ifcfg-infra_backup
+ Start the bridge and verify if the bridge is UP

# ifup ifcfg-infra_backup boot
# ifconfig admin-dmz
