NonStop NS-Series Operations Guide (H06.12+)

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 series systems, under each internal fabric object, you’ll
find its associated processor switch (p-switch) module and subcomponents. For Integrity
NonStop NS14000, NS1200, and NS1000 systems, there are no p-switches. Instead,
ServerNet connectivity is provided through 4PSEs located in the IOAMs or VIO
enclosures.
For more information on monitoring and recovery for external fabrics, see the appropriate
ServerNet cluster manual for your particular ServerNet cluster configuration and
hardware.
Monitoring the ServerNet Fabrics Using SCF
The SCF STATUS SERVERNET command displays a matrix for the ServerNet X fabric and a
matrix for the ServerNet Y fabric. Each matrix shows the status of the paths between all pairs of
processors.
Use the SCF STATUS SERVERNETcommand to display current information about the ServerNet
fabric. At a TACL prompt:
> SCF STATUS SERVERNET $ZSNET
1-> status servernet $zsnet
