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

4-Port ServerNet Extender (4PSE)
A component in NonStop NS14000 and NS1000 systems only, 4PSEs provide ServerNet
connectivity between processors and the IOAM enclosure (functionality provided by p-switches in
an NonStop NS16000 series system). 4PSEs are located in slot one (and optionally slot 2) of each
IOAM. They are connected to the processors through LSUs in NonStop NS14000 systems, directly
to the processors (with no LSUs) in NonStop NS1000 systems. FCSAs and G4SAs can be installed
in slots 3 through 5 of the two IOAMs in the IOAM enclosure for communications to storage devices
and subsystems as well as to LANs.
See “Monitoring the 4PSEs” (page 110).
Monitoring I/O Adapters and Modules
Use the Subsystem Control Facility (SCF) or the OSM Service Connection to monitor the FCSAs,
G4SAs, and ServerNet/DAs.
Monitoring the FCSAs
For an overview of using the OSM Service Connection to monitor system components, refer to
“Using the OSM Service Connection” (page 59).
To monitor the FCSA and its attached devices with SCF, use the SCF INFO and SCF STATUS
commands.
For example, to monitor all FCSAs using SCF:
> SCF STATUS ADAPTER $ZZSTO.#FCSA*, DETAIL
The SCF Reference Manual for the Storage Subsystem provides reference details and examples
for using the SCF INFO and SCF STATUS commands.
When monitoring FCSAs using the OSM Service Connection, the states of the FCSAs should indicate
normal operation. Table 19 lists the possible states for the FCSA.

DescriptionState
The resource is functioning normally and does not require
attention or service.
Service State: OK
The resource requires operator attention. This condition
sometimes generates an alarm, and the component that

requires attention is colored yellow in the tree pane and
in the Physical and ServerNet views of the view pane.
The resource requires service. This condition generates an
alarm, and the component that requires service is colored
