Managing One of the Star Topologies With OSM

OSM supports all topologies of a ServerNet cluster: the star topologies (

star

,

split-star

, and

tri-star

) and the newer

layered topology.

Differences Between OSM and TSM

If you use OSM to manage a cluster with one of the star topologies, see the next paragraphs for differences between
OSM and TSM.

Some Cluster Resources Are Represented Differently in OSM

The OSM representation of the 6770 cluster switch used in the star topologies is more complete than the TSM
representation. In particular, the ServerNet II Switch, the AC Transfer Switch, and the UPS are now viewable as
separate resources. To view these resources, expand the Switch Module resource.

The OSM names for some cluster resources are different from the TSM names:

OSM Name

TSM Name

Switch PIC * (PICs 0 through 7 connect to the nodes)

Switch-to-Node Link

Switch PIC * (PICs 8 through 11 connect to other switches)

Switch-to-Switch Link

ServerNet Local Node

Local Node

ServerNet Remote Node

Remote Node

Note: The full name for a Switch PIC is in the form: Switch PIC $ZZSMN.X.1.2. The last digit in the name is the PIC
number. In this example, the last digit is 2, which indicates a connection to a node.

Guided Procedures Are Replaced By or Launched By OSM Actions

OSM Changes

TSM Guided Procedure

Procedure has been replaced by the

Update Topology

action of the ServerNet Cluster resource.

Add Switch

Procedure has been enhanced to support switch types for all topologies. For the star topologies,
the procedure is launched by the

Replace

action of the ServerNet II Switch.

Replace Switch

Procedure has been replaced by separate

Firmware Update

and

Configuration Update

actions

of the ServerNet II Switch.

Update Switch

Procedure has been streamlined and renamed. It is now launched by the

Add Node to

ServerNet Cluster

action of the System resource.
