How to Configure Load Limits for a Node

Each cluster node can have its own set of load limits. You assign load factors to resource groups, and the load factors correspond to the defined load limits of the nodes. You can set soft load limits (which can be exceeded) or hard load limits (which cannot be exceeded).

  1. Assume the root role on one active node of the cluster.
  2. Start the clsetup utility.
    phys-schost# clsetup

    The clsetup menu is displayed.

  3. Choose the menu item, Other Cluster Tasks.

    The Other Cluster Tasks Menu is displayed.

  4. Choose the menu item, Manage Resource Group Load Distribution.

    The Manage Resource Group Load Distribution Menu is displayed.

  5. Choose the menu item, Manage Load Limits.

    The Manage load limits Menu is displayed.

  6. Type yes and press the Return key to continue.
  7. Type the option number for the operation you want to perform.

    You can create a load limit, modify a load limit, or delete a load limit.

  8. If you chose to create a load limit, select the option number for the node where you want to set the load limit.

    If you want to set a load limit on a second node, select the option number for the second node. After you have selected all the nodes where you want to configure load limits, type q.

  9. Type yes to confirm the nodes you selected in Step 8.
  10. Type the name of the load limit.

    For example, type mem_load as the name of a load limit.

  11. Type yes or no to specify a soft limit value.

    If you typed yes, type the soft limit value and press Enter.

  12. Type yes or no to specify a hard limit value.

    If you typed yes, type the hard limit value and press Enter.

  13. Type yes to proceed with creating the load limit.
  14. Type yes to proceed with the update.

    The message Command completed successfully is displayed, along with the soft and hard load limits for the nodes you selected. Press the Return key to continue.

  15. You can modify or delete a load limit by following the prompts in the clsetup utility.

    Return to the previous menu by typing q and pressing the Return key.
