Integrated Load Balancer VIP status is Unavailable

Products

• VCF Operations/Automation (formerly VMware Aria Suite)

Issue/Introduction

• Log Insight ILB Behavior issue, IP which is assigned to host shows that ILB is not connected.
• The ILB is currently connected to a node in the cluster, but eventually when it moves it appears to go to an unavailable state.
• After figuring out on which node the ILB IP is on, you reboot the node to release the IP and then you magically see it become available on another node.

Environment

VMware Aria Operations for Logs 8.18.x

Resolution

1. Log in to the UI and navigate to Management > Cluster
2. Locate the node with the Integrate Load Blancer role noted by (ILB) next to the node FQDN/IP in the Host column
3. If the (ILB) role is on the (Primary) node
   1. Click the hyperlinked Primary node's FQDN/IP in the Host column
   2. Click Restart Node
      
      Note: This will restart the services on the primary node, but will not reboot the appliance VM.
   3. In the Restart dialog, click the Restart button
   4. Wait for the ILB role to transfer to one of the other nodes in the cluster
      
      Tip: Click the Refresh data button (circle arrow icon) next to the Cluster heading to refresh the data in the page
   5. Go to Step 5
4. If the ILB role is on one of the worker nodes
   1. Click the Put this node into maintenance mode button (pause icon) next to the node with the ILB role
   2. In the Enter Maintenance Mode dialog click Continue
   3. Wait for the ILB role to transfer to one of the other nodes in the cluster
      Tip: Click the Refresh data button (circle arrow icon) next to the Cluster heading to refresh the data in the page 
   4. Click the Take this node out of maintenance mode button (play icon) next to the node that was placed into maintenance mode in step 4a
   5. In the Exit Maintenance Mode dialog click Continue
5. Verify the Integrated Load Balancer Virtual IP Address status changes to Available

Identify the node with the ILB role when the UI does not show (ILB) next to any node

1. Log in to the primary node as root via SSH
2. Run the command
   

   ip a | grep eth0:500

3. If the Integrated Load Balancer VIP is returned by the command, this is the node with the ILB role currently
4. If no result is returned, repeat steps 1-3 on the next node in the cluster
