Further, confirm that the server to be load balanced is operating normally because the problem may be due to an error in the
server.
- When it is possible that the hardware has failed, in cases that the server load balancer device status is "unknown" or the link
status is "down" that is not intended by infrastructure administrator.
The infrastructure administrator should request confirmation of the status from the administrator of the network device, to check
if the server load balancer has failed. The network device administrator should request a hardware maintenance person to take
corrective action when hardware has failed.
5. Take corrective action based on the results of checked scripts and files.
- When there are no errors in the scripts or files checked in 4.
Request confirmation from a tenant administrator or tenant user that there are no errors in the parameters taken over during the
L-Platform update.
- When there are errors in the scripts or files checked in 4.
The infrastructure administrator should log in to the server load balancer directly, delete the failed configuration (such as load
balancing rules), and modify any scripts or files containing errors.
6. Take corrective action based on the results of parameter checks.
- When there are no errors in the parameters taken over during the L-Platform update
Confirm with the administrator of the network device that the server load balancer configuration has not been modified, since
an unexpected modification may have been made to the definition.
- When there are errors in the parameters taken over during the L-Platform update
The infrastructure administrator should log in to the server load balancer directly, and delete the failed configuration (such as
load balancing rules).
7. Take corrective action based on the check results if definitions have been modified.
- When the network device administrator has not modified the configuration
Extract the server load balancer definitions and check the content. When inappropriate settings have been configured, log in to
the server load balancer directly, and modify the definitions.
- When a network device administrator has modified the configuration
Check if the configuration modification is necessary.
- When the configuration modification is not necessary
The infrastructure administrator should log in to the server load balancer directly, and delete or modify the problem-causing
configuration (such as load balancing rules).
- When configuration modifications were necessary based on the system operation policy
Review if the details of scripts, parameter files, and interface configuration files are based on the operation policy.
11.4.3.2 When a Changing State of Server Load Balancer is Detected during Status
Confirmation Using the ROR Console
Use the following procedure to confirm the status of server load balancers.
1. Select the network device of the server load balancer on which an error has occurred from the network device tree.
2. Select the [Resource Details] tab.
3. Confirm the status of the server load balancer.
4. Identify the L-Platform in use.
a. Confirm the name of the server load balancer allocated using auto-configuration by checking the items displayed in the results
for the rcxadm netdevice show command (AllocatedResources[SLB]).
