IP agent for same mac address interface

Hi all,

Our environment as the following:
OS: redhat 6.5
VCS: VCS 6.2.1

Our server have two physical network port, namely eth0 and eth1.
We do create tagged vlan, vlan515, vlan516, vlan518, vlan520 based on eth0 and eth1.

We are able to create resource IP on vlan518 and failover between two nodes.

However, when we create resource IP on vlan515, it is not able to bring it online.

According to the link, https://support.symantec.com/en_US/article.TECH214469.html,
It knows that duplicate mac address would cause the problem.
However, it can't figure out where "MACAddress" attribute in VCS Java Console as mentioned in the solution.

I did manually add "MACAddress" attribute on main.cf on either NIC or IP resource, it come with not support with haconf -verify command.

Any hints or solution for the problem when configure the IP agent resource on same mac address?

Thanks,

Xentar

    Just checking you already have an IP on vlan515 as VCS IP agent only adds logical IPs, not the base IP.

    Hi All,

    We figured that the problem is due to the VIP is being used by other. And it's strange that we can enable it by ifconfig command.

     

    Thanks,

    Xentar,

     

      Thank you for the explorer. Could you also provide the following output.

     

    #cat /proc/net/bonding/*

     

    Thanks,

    Going over the IP_A.log now.

    What interfaces make up bond0 and bond2?

    EDIT:

      Please collect a Veritas explorer from each node in the cluster. This will provide us with the logs and configuraiton information needed to move forward.

     

    Thank You,

    I would log a call with Symantec as I believe get_ipv4_status is a Symantec program (as oppose to an O/S library) and it looks as though this is not working correctly.

    Hi Mike, Sudhir and others,

    Attached please find IP_A.log.

    [root@FSCSTGU1 bin]# ifconfig vlan515:1 10.30.215.101 netmask 255.255.255.0 up

    [root@FSCSTGU1 bin]# ifconfig vlan515
    vlan515   Link encap:Ethernet  HWaddr E0:97:96:13:FF:E5
              inet addr:10.30.215.102  Bcast:10.30.215.255  Mask:255.255.255.0
              inet6 addr: fe80::e297:96ff:fe13:ffe5/64 Scope:Link

              UP BROADCAST RUNNING MASTER MULTICAST  MTU:1500  Metric:1

    From IP_A.log, it shows that VCS DBG_5 IP:ODSDBU1_IP:monitor:Interface vlan515 address does not matchIP.C:get_ipv4_status[371], 
    but it can be manually added by ifconfig command as the above.

     

    Thanks,
