NonStop Operations Guide for H-Series and J-Series RVUs

3. Check these objects for:
a. If an 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 an 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 an object icon is covered by a yellow arrow, there is a problem on a subcomponent
of that object. Expand the object to locate the subcomponent object reporting the alarm
or problem attribute.
For NonStop NS16000 series systems, under each internal fabric object, you’ll find its
associated processor switch (p-switch) module and subcomponents.
For NonStop NS2400 series, NS2300, NS2200 series, NS2100, NS2000 series,
NS14000 series, NS1200, and NS1000 systems, there are no p-switches. Instead,
ServerNet connectivity is provided through 4PSEs located in the VIO enclosures (or IOAMs,
where supported).
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 SERVERNET command to display current information about the ServerNet
fabric. At a TACL prompt:
> SCF STATUS SERVERNET $ZSNET
1-> status servernet $zsnet
