Guided Procedures Have Changed
Guided Procedures Have Changed
Some of the TSM guided procedures used with a ServerNet cluster have been 
replaced by new actions in the OSM Service Connection. Other guided procedures are 
now launched directly by an action in the OSM Service Connection instead of from the 
guided procedures interface.
Options for Changing Topologies
To update your cluster to the split-star or tri-star topologies, you can use the OSM 
Update Topology interactive action which replaces the TSM Add Switch guided 
procedure. The tasks are described in the OSM Service Connection online help, which 
is accessible when you perform the Update Topology action.
If you prefer, you can still use the TSM Add Switch guided procedure as described in 
the ServerNet Cluster Manual. 
If you need to migrate from one of the star topologies to the layered topology, see the 
ServerNet Cluster 6780 Planning and Installation Guide.
If you use the OSM Update Topology action to update to the split-star or tri-star 
topology, you should still refer to the ServerNet Cluster Manual for planning 
information. Most of the information in the ServerNet Cluster Manual still applies, but:
•
References to TSM software generally apply to OSM software. To learn more 
about the differences, see For More Information About OSM.
•
The OSM switch names are slightly different than the TSM switch names.
•
The TSM client and server versions are not relevant because you should be 
running the OSM package on all nodes. The OSM package supports all network 
topologies of a ServerNet cluster.
TSM Guided Procedure OSM Changes
Add Switch Procedure has been replaced by the Update Topology action 
of the ServerNet Cluster Resource. The tasks have been 
streamlined and are documented in the OSM Service 
Connection online help. 
Replace MSEB Procedure is now launched by the Replace action of the 
MSEB.
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 Switch Module, the ServerNet II 
Switch, the AC Transfer Switch, or the UPS. 
Update Switch Procedure has been replaced by separate Firmware Update 
and Configuration Update actions of the ServerNet II Switch.
Configure ServerNet Node Procedure has been streamlined and renamed. It is now 
launched by the Add Node to ServerNet Cluster action of the 
System resource.
