Configuring Agent Parameters

Agent parameters specify how you want to connect to your storage. This section provides steps to configure parameters such as polling time, periodic device discovery time, smart monitoring, out-of-band storage management, and enabling JBOD support.

  1. From the main window, choose View > Agent Options Management. The Agent Options Management window is displayed.
  2. NOTE: Agent Options Management might not be available if one or more groups are configured and one of them is selected in the main window. To enable it, select an icon other than a Group, and click View.

  3. For Monitoring Frequency, type the interval time in seconds that you want to poll for status.
  4. This value entered is the interval between successive polling for any status change of devices, array controllers, and enclosure monitoring by the agent. The default value is 60 seconds. If you want the console to update more frequently with device status changes, decrease this value.

    NOTE: Increasing the polling interval could negatively impact error messaging under heavy I/O load.

  5. For Periodic Device Discovery Time, type the value in minutes you would like to have the program check for new devices.
  6. The periodic device discovery value is used to determine how often each device ID is scanned for a new device. The default value of 0 specifies not to scan for new devices. Note that device IDs are scanned less frequently, as the numerical value entered increases.

    Conversely, device IDs are scanned more frequently, as the numerical value entered decreases. Five minutes is the minimum value that can be entered.

  7. For Interval of trap generation for an event, type the amount of time in seconds between the sending of each trap message.

    If the value is 60 seconds or greater: a message is sent at that interval, for that particular trap, until the event is cleared or corrected. For example, if a fan fails, a message regarding that fan failure is sent every 60 seconds until fixed.

    If the value is 0: SANscape (and therefore SANscape Alert) sends only one message regarding that particular event. For example, if a fan fails, only one email is sent.

  8. For Timeout of heartbeat lost, set the amount of time in minutes to wait between the sending of failed server messages. The default value is 15; the value range is 1 to 30 minutes.
  9. To enable SMART Monitoring, select the check box.
  10. SMART monitoring is a method for hard drives to report predicted failures. Most disk vendors supply drives with this feature. The agent monitors this feature by issuing an unsolicited request sense. SMART monitoring can be turned off if this request causes conflicts with the underlying host operating system device drivers. For more information on SMART monitoring, refer to the SANnet II Family RAID Firmware User's Guide for your array.

  11. To enable JBOD support, see Enabling JBOD Support.

  12. The parameters under Controller Primary Agent Information, including the Password fields, pertain to out-of-band management.

    See Out-of-Band Storage Management for information about configuring these parameters.

  13. If you have changed any of the previous options, click OK to save your changes.

  14. Click Close to finish the procedure.

Enabling JBOD Support

Use Just a Bunch of Disks (JBOD) support only when you have a JBOD connected directly to the server. This enables you to monitor the peripheral device condition and events. If you have a JBOD connected to the RAID array, the RAID controllers monitor the JBOD condition and events for you.

NOTE: Enabling JBOD support could negatively impact I/O.

  1. From the main window, choose View > Agent Options Management. The Agent Options Management widnow is displayed.
  2. Select Enable JBOD support.

    See Monitoring JBODs for details.
