Managing One of the Star Topologies With
OSM

Differences Between OSM and TSM

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:

TSM Name

OSM Name

Switch-to-Node Link

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

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

Local Node

ServerNet Local Node

Remote Node

ServerNet 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

TSM Guided Procedure

OSM Changes

Add Switch

Procedure has been replaced by the

Update Topology

action of the

ServerNet Cluster resource.

Replace 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.

Update Switch

Procedure has been replaced by separate

Firmware Update

and

Configuration Update

actions of the ServerNet II Switch.
