Creating and deleting load balancer pools

You can create and delete load balancer pools in a network container that has a load balancer. This topic contains the following sections:

To create a load balancer pool

1. Access the Manage Load Balancers window as described in Managing-load-balancers.
2. Click the Add Load Balancer Pool icon .
    The Create Load Balancer Pool dialog box is displayed.
   

3. Enter a unique name for the new load balancer pool.

   Important

   Review the following considerations when creating the name for the load balancer pool:

   Ensure that the load balancer pool name you enter, when combined with the SOI name, does not exceed 30 characters. The unique name for load balancer pool is created by concatenating the load balancer pool name and the SOI name; the length of the name length (that is, the string length of the load balancer pool name plus the SOI name) must not exceed 30 characters (in particular for VPX load balancers). If the name does exceed 30 characters then the load balancer pool creation fails for BMC Network Automation.

   Do not include spaces in the load balancer pool name. If spaces are included, a BMC Network Automation exception error is generated. The text of the error message is similar to the one in this example:

   ERROR 1:Root Cause Info:Severity: CRITICAL Error:
   Cannot create Load Balancer Pool. Exception while creating LBP: Error in Add load balancer pools action 1 for device <name of network container> in BNA job <job number>: Device Create Pool communication failure.
   ChatException: chat phrase [long command] found in [serverfarm New Pool ^ % long command detected at '^' marker. <server name/network container name - Load Balancer name> ].
4. (Optional) Enter a useful, distinguishing description for the new pool.
5. Select TCP or UDP for the transport protocol.
   Other transport protocols are not valid for load balancer pool creation.
6. Choose a corresponding application protocol, if available, or enter a port number.
7. Specify a server network. If none is available, add one from the Add Server Networks dialog box.
8. Specify a corresponding client network from the drop-down list.
9. Specify a virtual IP address by selecting Create New or by selecting an existing address from the drop-down list.
   When you select Create New, the system automatically assigns the new IP address.
10. (Optional) In the Additional Parameters section, select any additional parameters for the pool:
    1. Select the Vendor and Device Type.
        These selections populate the Parameter options.
    2. Select the Parameter to pass to the load balancer.

    3. Enter a value for the selected parameter, and click Add.
       Continue to add parameters and values as needed.

       Note

       You can set up additional parameters that can be selected, as described in Creating-custom-parameters-for-load-balancers.

11. Click Save.
    The load balancer pool is created. You can manage pool entries as described in Creating-and-managing-server-entries-in-a-load-balancer-pool.

To delete a load balancer pool

1. Select a pool name from the Load Balancer Pools table.
2. Click the Delete Load Balancer Pool button. 
   The pool is removed.
