Controller Primary Agent Information
- Out-of-Band Storage Management
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.
The following figures show examples of in-band and out-of-band storage
management configurations:
In-Band Management
Out-of-Band Management
Using
Out-of-Band Management
NOTE: Controller, SAF-TE, SES, PLD,
and drive firmware cannot be upgraded through out-of-band management.
NOTE: If you assign an IP address
to an array to manage it out-of-band, for security reasons consider using
an IP address on a private network rather than a publicly routable network.
Using the controller firmware to set a password for the controller limits
unauthorized access to the array. Changing the firmwares Network Protocol
Support settings can provide further security by disabling the ability to
remotely connect to the array using individual protocols such as HTTP, HTTPS,
telnet, FTP, and SSH. Refer to the Communication Parameters
section of the SANnet II Family RAID Firmware Users Guide for
more information.
- Make sure you have set up a static or
dynamic IP address for the array.
If the program has been configured already to manage the array through
in-band, you can set the IP address through Change Controller Parameters.
To set the IP address, see the Peripheral Tab. If the program
has not been configured yet, you can set the IP address through an RS-232
terminal. Refer to the SANnet II Installation, Operation, and Service
Manual for your array.
- After setting the IP address, reset
the controller.
Choose Array Administration > Controller Maintenance, and
then click Reset the Controller.
- Select the server.
- Choose View > Agent Options Management.
- Type the IP address of the array in the
IP Address field, and click Add.
- If you have created a controller password
for the array using the firmware application, type it in the Password
field, and then re-type it in the Verify Password field.
NOTE: By default there is no password set for the array. For
information on creating or changing the controller password, refer to
the SANnet II RAID Firmware Users Guide for your array.
- Check Out-Of-Band Agent preferred over
In-Band, and click OK.
NOTE: With this option checked, out-of-band
becomes the preferred method of storage management. If the out-of-band
configuration is removed, the program reverts to in-band storage and
monitoring after you start/restart the services.
- For SANscape
to recognize the out-of-band array and display an out-of-band HBA icon
in the main window, you need to send a Probe command to the server.
Choose View > View Server,
and then click Probe.
- If the program has not been configured
to manage the array, you need to assign the server to manage the controller.
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 Menu Bar under the View menu.
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
-
Select the
server.
- Choose View > Agent Options Management.
- Select the array's IP address that you
want to remove, click Remove, and click OK.
The HBA remains displayed in the main
window; to remove it, you need to unassign and reassign the managing
server.
- From the main window, choose Array
Administration > Controller Assignment.
- Select the controller for which you want
to unassign a server.
- From the Server to manage this controller
list box, select none, and click Apply.
- Click Close to confirm.
- Reassign the managing server following
the steps in Controller Assignment.
