ServerNet Manager Help

To access the ServerNet Manager from the NonStop Cluster Management Suite (NCMS) window, select the ServerNet Manager application tab. If the tab is not present in the window, select File from the menu bar and choose the Applications menu item. Select ServerNet Manager from the application list and click on OK to start the ServerNet Manager.

Basic Functionality: Monitoring/Managing the ServerNet SAN

The ServerNet Manager: Only users with root permission user can designate ServerNet SAN communications paths, reset the link exception and LLSC statistics, and adjust the time interval for retrieving the state/status/statistics/register content information.

ServerNet Manager Tab

When the ServerNet Manager application tab is selected:

ServerNet Manager Views

To display one of the ServerNet Manager views, select the associated  view tab.
 

ServerNet States View

The ServerNet States view is used to monitor the following types of information: The ServerNet States view can be used to perform the following types of operations: See ServerNet States Help for details.
 

I/O Statistics View

The I/O Statistics view is used to monitor the ServerNet SAN read and write operation count and read and write byte count between nodes. See  I/O Statistics Help for details.
 

Link Exceptions View

The Link Exceptions view is used to monitor and/or reset the link exception statistics on a node or fabric basis. Link exceptions are recorded by the ServerNet PCI Adapter (SPA) in each node when any one of a number of problem are detected in the communications traffic at the receiving end of a ServerNet SAN link. See Link Exceptions Help for details.
 

LLSC Recovery View

The LLSC (link layer self check) Recovery view is used to monitor and/or reset key statistics related to the SAIL ASIC self-check and recovery cycles for a node. The SAIL ASIC provides the ServerNet SAN ports on the SPA; the SAIL ASIC self checks (aborts normal operation) when it has to wait too long for PCI bus access. The SPA driver (SPAD) recovers the SAIL ASIC from self checks, but the magnitude of the self-check statistics needs to be monitored to determine if the SPA needs to be moved to a higher priority PCI slot in the node. See  LLSC Recovery Help for details.
 

SPA Registers View

The SPA Registers view is used to monitor the contents of several key registers on the SPA for a node, including the SAIL ASIC chip ID register, node ID register, SPA configuration register, SAIL ASIC transmit and receive port reset and enable controls, and the SAIL ASIC interrupt cause mask register. See SPA Registers Help for details.

ServerNet Manager Menu Bar

The ServerNet Manager menu bar at the top of the NCMS window is used for the following operations:

Actions Menu

Update now
Retrieve the most current data available for all nodes in the cluster for all ServerNet Manager views.

Set update periods
(This menu item appears only for users with root permission.) Display the Set Update Periods dialog box, which is used to set the update period for the ServerNet Manager and ServerNet Agent. The agent update period defines how frequently the agent retrieves data from the SPADs on each node. The manager update period defines how frequently the manager retrieves data from the agent. For more information on manager/agent update periods and how to use the Set Update Periods dialog box, see Set Update Periods Help.
