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.
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.
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.
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.
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.
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.
