System Input/Output Configuration Analyzer On The Se And Hmc - IBM z13s Technical Manual

11.5.11 System Input/Output Configuration Analyzer on the SE and HMC

The System Input/Output Configuration Analyzer task supports the system I/O configuration
function.
The information that is needed to manage a system's I/O configuration must be obtained from
many separate sources. The System Input/Output Configuration Analyzer task enables the
system hardware administrator to access, from one location, the information from those
sources. Managing I/O configurations then becomes easier, particularly across multiple
servers.
The System Input/Output Configuration Analyzer task runs the following functions:
Analyzes the current active IOCDS on the SE.
Extracts information about the defined channel, partitions, link addresses, and control
units.
Requests the channels' node ID information. The Fibre Channel connection (FICON)
channels support remote node ID information, which is also collected.
The System Input/Output Configuration Analyzer is a view-only tool. It does not offer any
options other than viewing. With the tool, data is formatted and displayed in five different
views. The tool provides various sort options, and data can be exported to an UFD for later
viewing.
The following five views are available:
PCHID Control Unit View shows PCHIDs, channel subsystems (CSS), channel-path
identifiers (CHPIDs), and their control units.
PCHID Partition View shows PCHIDS, CSS, CHPIDs, and the partitions in which they
exist.
Control Unit View shows the control units, their PCHIDs, and their link addresses in each
CSS.
Link Load View shows the Link address and the PCHIDs that use it.
Node ID View shows the Node ID data under the PCHIDs.
11.5.12 Automated operations
As an alternative to manual operations, an application can interact with the HMC and SE
through an API. The interface allows a program to monitor and control the hardware
components of the system in the same way you can. The HMC APIs provide monitoring and
control functions through SNMP and the CIM. These APIs can get and set a managed
object's attributes, issue commands, receive asynchronous notifications, and generate SNMP
traps.
The HMC supports the CIM as an extra systems management API. The focus is on attribute
query and operational management functions for z Systems servers, such as CPCs, images,
and activation profiles. z13s servers contain a number of enhancements to the CIM systems
management API. The function is similar to that provided by the SNMP API.
For more information about APIs, see z Systems Application Programming Interfaces,
