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 NameTSM 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 NodeLocal Node
ServerNet Remote NodeRemote 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 ChangesTSM 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Procedure has been replaced by the Update Topology action of the ServerNet Cluster resource.Add Switch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Procedure has been replaced by separate Firmware Update and Configuration Update actions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.
