The Agent Options Management window lets you configure agent parameters, including polling time, periodic device discovery time, SMART monitoring, and enabling 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 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 means do 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:
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: Sun StorEdge Configuration Service (and therefore Sun StorEdge Diagnostic
Reporter) 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 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 Sun StorEdge 3000 Family RAID Firmware User's Guide for your array.
See Controller Primary Agent Information
- Using Out-of-Band Storage Management for information about
configuring these parameters.
The Setting Agent Options notification box is displayed showing
the server's TCP/IP address.
Use JBOD support only when you have a JBOD connected directly to the
workstation. 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. See
Monitoring JBODs for details. The out-of-band storage management capability enables you to monitor
and manage arrays over the network using TCP/IP.
Unlike in-band storage management (the standard method of storage management),
which requires the agent to be running on the server that is physically
attached to the storage, out-of-band storage management does not require
the agent to be running on the server that is physically attached to
the storage. With out-of-band storage management, if the server that
is attached to the storage is shut down, monitoring and maintenance
is unaffected. Caution: If you assign an IP address to an array in order to
manage it out-of-band, for security reasons make sure that the IP address
is on a private network, rather than a publicly routable network. When
your array is on a public network, it is vulnerable to outside attacks. In-band storage and monitoring of the array requires the Sun StorEdge Configuration Service Agent to be running on the server that is physically connected to the storage. Out-of-band management and monitoring of the array
does not require the Sun StorEdge Configuration Service Agent to be running on the server that is physically connected to the storage. Using Out-of-Band Management Note: Controller, SAF-TE, and Drive firmware cannot be upgraded through
out-of-band management. Caution: If you assign an IP address to an array in order to
manage it out-of-band, for security reasons make sure that the IP address is on a private network,
rather than a publicly routable network. If Sun StorEdge Configuration Service has been configured already to manage the array through in-band, you can set the IP address through the Network tab on the Change Controller Parameters window. If Sun StorEdge Configuration Service has not been configured yet, you can set the IP address through an RS-232 terminal. Refer to the Sun StorEdge 3000 Family Installation, Operation, and Service Manual for your array. NOTE: With this option checked, out-of-band becomes the preferred method of storage management. If the out-of-band configuration is removed, Sun StorEdge Configuration Service reverts to in-band storage monitoring after you start/restart the services. NOTE: By default there is no password set for the array. For information on creating or changing the password, refer to the Sun StorEdge 3000 Family RAID Firmware User's Guide for your array.
Choose Array Administration > Controller Assignment. Select a server from the Server to manage
this controller list and click Apply.
An out-of-band HBA is displayed in the main window and View HBA Card is displayed in the Main Menu under View. NOTE: If an out-of-band HBA is not displayed in the window, reset the controller. To Remove an Array From Out-of-Band Management
The HBA remains displayed in the main window; to remove it, you need to unassign and reassign the managing server.
