hi Experts,

I am configuring failover group for OTD on jcs according to this doc:14.2 Creating and Managing Failover Groups

But always failed with wrong vip together with

eth0      Link encap:Ethernet  HWaddr C6:B0:69:38:64:3D

          inet addr:10.196.109.82  Bcast:10.196.109.83  Mask:255.255.255.252

node2:

eth0      Link encap:Ethernet  HWaddr C6:B0:2A:18:CF:2C

          inet addr:10.196.110.194  Bcast:10.196.110.195  Mask:255.255.255.252

Best regards

Lan

    Hello,

    I guess the reason of failure is clear:

    Decide the unique VIP address that you want to assign to the failover group.

    • The VIP addresses should belong to the same subnet as that of the nodes in the failover group.

    In your case, 10.196.109.82 and 10.196.110.194 are NOT on the same subnet (255.255.255.252). Either one of those has to change its IP, or the subnet mask has to be modified.

    hi Jiri,

    Thanks for the help.

    I think ip and subnet mask should be assigned by cloud and cann't be changed by customer, I will give a try on it.

    Best regards

    I tested, after change ip of OTD, I lost the ssh connection forever, have to recreate one.

    I think the ip created by jcs can not be modified, have to looking for other sulotion.

    Best regards
