Monitoring all port-HBA traffic: many-to-many connections

When many-to-many connections are established between HBAs and ports, you must make sure that all traffic between HBAs and ports is monitored.

Before you begin

  • Required role: Storage Administrator (System Resource Management)
  • You must enable the Device Manager - Storage Navigator secondary window. For details, see the System Administrator Guide of your storage system.

Procedure

  1. Click Reports Performance Monitor Server Priority Manager to open the Server Priority Manager window.

  2. Click to change to Modify mode.

  3. In the Server Priority Manager window, click Server Priority Manager. The Server Priority Manager main window appears.

  4. Click the WWN tab.

    Two trees are displayed on the left side of the WWN tab. The upper-left tree lists ports in the storage system.

  5. Select All from the list at the top right corner of the window.

  6. In the upper-left tree, double-click a port.

  7. Double-click Non-Monitor below the specified port.

    If there are any host bus adapters whose traffic with the specified port are not monitored, those host bus adapters are displayed below Non-Monitor.

  8. Right-click Monitor, and then select Add WWN to open the Add WWN window.

  9. In the Add WWN window, specify the WWN and the SPM name.

    Expand the WWN list to show the WWNs of the host bus adapters that are connected to the port but are not monitored. These host bus adapters are the same as that displayed in step 7. From that list, select a WWN and specify the SPM name (up to 64 characters).
    NoteIt is recommended that you specify the same names for the SPM names and the host bus adapter nicknames defined in LUN Manager for convenience of host bus adapter management. In the Performance Monitor window, both the SPM names and the nicknames are displayed as the aliases of host bus adapters (WWNs), so if you use the same names, management of the host bus adapters is easier.

  10. Click OK. The selected WWN (of the host bus adapter) is moved from Non-Monitor to Monitor.

    If the specified host bus adapter is connected to other ports, after clicking OK, a message appears asking whether to change the settings of that host bus adapter for other ports. Apply the same setting to all of the ports.

  11. Repeat steps 8 to 10 to move all host bus adapters from below Non-Monitor to below Monitor.

    Up to 32 host bus adapters (WWNs) can be monitored for one port. If more than 32 host bus adapters are connected to one port, the traffic statistics for all host bus adapters cannot be monitored. Consider the intended use of each host, and place the host bus adapters that do not need to be monitored below Non-Monitor.
    NoteWhen you disconnect a host that has been connected via a cable to your storage system or change the port to the another port of the host, the WWN for the host will remain in the WWN list on the WWN tab. To remove the WWN from the list, you need to delete the WWN using LUN Manager. For details, see the Provisioning Guide of your storage system.

  12. In the Server Priority Manager main window click Apply to apply the settings to the storage system.

  13. If you add a port or a host bus adapter to the storage system after the settings above, the traffic for the new port or host bus adapter will not be monitored. In this case, follow this procedure again to make sure all traffic between host bus adapters and ports is being monitored.
