About Switch Network Management

You must enable the Switch Network Manager (SNM) software on the HMC if the Cluster 1600 is configured with the pSeries HPS. SNM initializes the pSeries HPS networks, monitors network status, performs recovery for hardware systems, and provides error reporting.

As a first step after installing or reconfiguring your cluster, you may use the Display Cluster components task to verify that all installed servers and switches are visible to the HMC.

Before enabling the SNM software, you must select the plane topology for your HPS network, using the Set Logical Topology task. You must choose from a list of supported topologies in order to enable the SNM software.

Before enabling the SNM software in normal mode, you may use the Enable SNM Software for Switch Network Verification task to identify that your HPS network is correctly wired and to verify that the hardware components are functional.

The Switch Network Management application uses the SNM software to provide the following functions:

• View switch, adapter, and link information
• Power switch boards on and off
• Perform diagnostic functions
• View power environmentals
• View software trace files
• View switch network management properties

You can perform the following tasks from the Overview:

• Display Cluster Components
• Set Logical Topology
• Enable SNM Software for Switch Network Verification
• Enable SNM Software for Normal Operation
• End-Point View
• Switch Topology View
• Management Properties
• View Trace
• Disable SNM Software
