11.4.3 Server Load Balancer Status Confirmation

This section explains the confirmation procedure of server load balancer status.


11.4.3.1 When an L-Platform Using a Server Load Balancer is Identified

Use the following procedure to confirm the status of server load balancers.

  1. In the orchestration tree, select the network device of a server load balancer under the L-Platform.

  2. Select the [Resource Details] tab, and click the link for [Preserved resource] of [Network Device] of [Basic Information of Network Device].

    The [Resource Details] tab of the network device is displayed.

  3. Confirm the displayed detailed information.

    When the target network device is in redundant configuration, confirm both the devices are in active status and standby status.

    • When there is a link for [Launch Network Device Web UI] in [Hardware Details]

      1. Click the link and start the server load balancer management screen.

      2. Confirm event log and status(interface, system condition and operation status) from the started management window, and check the error detected by the server load balancer.

    • When there is no link for [Launch Network Device Web UI] in [Hardware Details]

      Confirm the following information displayed in the Main Panel.

      Basic Information - Device Status

      The status of the server load balancer is displayed.
      When the status is something other than "normal" that is not intended by infrastructure administrator, it indicates that an error might have occurred.

      Port Information - Link Status

      The port status of the server load balancer is displayed.
      When the status is something other than "up" that is not intended by infrastructure administrator, it indicates that a port error might have occurred.

      Additionally, confirm status(system condition and operation status) by logging the server load balancer directly, and check the error detected by the server load balancer.

  4. Confirm the status of the server load balancer.

    • When server load balancing is not performed as expected or an event log is output

      The infrastructure administrator must confirm if the following items using auto-configuration are correct.

      • Scripts for configurations

      • Parameter files

      • Configuration files for interfaces

      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.

    1. 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]).

    2. Confirm the name of the L-Platform using the server load balancer by checking the items in results displayed for the rcxadm slb show command (L-Platform Name). Specify the server load balancer name confirmed in a. as the server load balancer name to be specified for the name option.

  5. For the confirmation procedure after this, refer to the operation after step 3. of "11.4.3.1 When an L-Platform Using a Server Load Balancer is Identified".

See

  • For details on server load balancer operations (login, status confirmation, definition extraction, definition modification, etc.), refer to the manuals of server load balancers.

  • For details on the rcxadm netdevice command, refer to "3.8 rcxadm netdevice" in the "Reference Guide (Command/XML) CE".

  • For details on the rcxadm slb command, refer to "3.12 rcxadm slb" in the "Reference Guide (Command/XML) CE".
