ServerNet Resources: Monitoring and Recovery Monitoring the ServerNet Fabrics Using OSM

ServerNet clusters) for communication between systems.The ServerNet fabrics consist of two entirely separate communication paths—the X fabric and the Y fabric.

Note. If the system is a member of a ServerNet cluster, ServerNet connections to other members are accomplished by extending the ServerNet fabrics outside the system. Such external connections make up the external ServerNet fabrics. The ServerNet Cluster Manual provides additional information about monitoring the external ServerNet fabrics.

To monitor the status of the ServerNet fabrics:

•

•

Use the OSM Service Connection to check the communication between processor enclosures, I/O enclosures, and systems.

Use the Subsystem Control Facility (SCF) to check the status of interprocessor communication on the X and Y fabrics.

Monitoring the ServerNet Fabrics Using OSM

To check the ServerNet fabrics:

1.Log on to the OSM Service Connection.

2.Expand the tree pane to locate and select the internal or external ServerNet fabric objects:

a.The X and Y internal ServerNet fabric objects are located under the System and Fabric Group objects.

b.The X and Y external ServerNet fabric objects are located under the ServerNet Cluster object (if your system is part of a ServerNet cluster).

3.Check the fabric objects for:

a.If a fabric object icon is covered by a red or yellow triangular symbol, check the Attributes tab in the details pane for degraded attribute values. The Service State attribute is only displayed in the Attributes tab if it has a value of other than OK. If a degraded Service State is indicated, there will be an associated alarm to provide more information about the cause of the problem.

b.If a bell-shaped symbol is displayed next to a fabric icon in the tree pane, select the Alarms tab from the details pane. To get more information on an individual alarm, click to select the alarm, then right-click and select Details.

c.If a fabric object icon is covered by a yellow arrow, there is a problem on a subcomponent of that fabric. Expand the fabric object to locate the subcomponent object reporting the alarm or problem attribute.

For Integrity NonStop NS16000 systems, under each internal fabric object, you’ll find its associated processor switch (p-switch) module and subcomponents. For Integrity NonStop NS14000 and NS1000 systems, there are no p-switches. Instead, ServerNet connectivity is provided through 4PSEs located in the IOAMs.

For more information on monitoring and recovery for external fabrics, see the appropriate ServerNet cluster manual for your particular ServerNet cluster configuration and hardware.
