The Agent Options Management window lets you configure agent parameters
including polling time, device discovery time, SMART monitoring, the controller
password, and JBOD support. It also lets
you specify whether to use out-of-band
or in-band storage management.
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 SANscape Agent. The default value is 60 seconds. If you want
the SANscape 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 by SANscape to determine
how often each device ID is scanned for a new device. The default value
of 0 means SANscape does not 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.
If the value is 60 seconds or greater: SANscape sends a message
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 zero: SANscape (and therefore SANscape Alert) sends
only one message regarding that particular event. For example, if
a fan fails, only one email is sent.
SMART monitoring is a method for hard drives to report predicted failures.
Most disk vendors supply drives with this feature. The SANscape 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. The Setting Agent Options notification box is displayed showing
the server's TCP/IP address.
