Appliance found with the Network Adapter Missing on Boot


on boot appliance is dropping the assigned network adapter. 


Steps to clear if adapter is disabled and appliance is not on network after reboot.

First, to gain local access to the appliance, press ALT-F2 from a keyboard and monitor directly connected to the Unitrends Appliance (or from IPMI). Login with the root credentials. 

    From command line interface 

    Check for existing ifcfg of adapters
    [root@Recovery-8002 ~]# ls -rlasth /etc/sysconfig/network-scripts/ifcfg*
    4.0K -rw-r--r-- 1 root root 254 Aug 24  2018 /etc/sysconfig/network-scripts/ifcfg-lo
    4.0K -rw-r--r-- 1 root root 408 May  1 11:07 /etc/sysconfig/network-scripts/ifcfg-eno1
    [root@Recovery-8002 ~]# 
    enable eno1
    [root@Recovery-8002 ~]#  ifup eno1
    RTNETLINK answers: File exists

    [root@Recovery-8002 ~]# 
    Confirm eno1 is now enabled and shows assigned IP addr:
    [root@Recovery-8002 ~]# ifconfig eno1
    eno1: flags=4163<UP,BROADCAST,RUNNING,MULTICAST>  mtu 1500
            inet  netmask  broadcast

    Link activity lights should populate on adapters


    Found onboot setting in ifcfg-eno1 of the adapter displaying as onboot=no

    [root@Recovery-8002 ~]# grep -i onboot /etc/sysconfig/network-scripts/ifcfg*
    [root@Recovery-8002 ~]#

    This can be confirmed within the UI:
    Configure > Appliances, Network > select adapter and edit:

    User-added image

    Expectations are that "Start Adapter on Boot" is checked, if found unchecked select then save to apply.

    Please refer to the following section of the admin guide for additional settings as needed.
