ServerNet Cluster Web

cluster, the external fabrics consist of the fiber-optic cables and cluster switches

that provide the infrastructure for routing ServerNet packets between ServerNet

nodes. Each Nonstop™ S-series server also has internal ServerNet fabrics that route

ServerNet packets either to a ServerNet device within the server or out across the

external fabrics to another node.

What are guided procedures? Guided procedures are software tools that assist in

the configuration or replacement of system components. Guided procedures

automate some of the steps in complex tasks, such as:

Adding a cluster switch to expand the topology■

Adding a ServerNet node to a cluster■

Troubleshooting a ServerNet fabric■

Replacing an SEB with an MSEB■

Replacing a defective MSEB with another MSEB■

Replacing a cluster switch or cluster switch component■

With the introduction of the HP NonStop Open Service Management (OSM)

package, some guided procedures have been replaced with interactive

actions. If you use OSM to manage a cluster, see How OSM Replaces TSM

and the Guided Procedures.

Dial-Outs

How do dial-outs work in a ServerNet cluster?

Dial-outs for clustered servers generally work the same as dial-outs for nonclustered

servers. However, for some types of switch failures, multiple dial-outs can occur

from all the nodes connected to a 6770 switch. For ServerNet clusters using the

layered topology, a failure causes only one dial-out from any 6780 switch in the

cluster.

Documentation

Which manuals document the NonStop™ ServerNet Cluster product?

The ServerNet Cluster Manual and the NonStop™ Himalaya Cluster

Switch Hardware Installation and Support Guide document ServerNet

clusters using the star topologies and the 6770 switch.

●

The ServerNet Cluster 6780 Planning and Installation Guide and the

ServerNet Cluster 6780 Operations Guide document ServerNet

clusters using the layered topology and the 6780 switch.

In addition, online help is available for the guided procedures that support

configuration and replacement operations in a ServerNet cluster.
