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.
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.
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.
