How to find out the names of the nodes in a veritas cluster

Here is the command to find out the names of the nodes in a veritas cluster:

grep SystemList /etc/VRTSvcs/conf/config/


grep AutoStartList /etc/VRTSvcs/conf/config/

Here is some more information about Veritas Cluster commands:

Term/Cmd/Pkg Description Command / File
VRTSvcs VERITAS Cluster Server
VRTSvcswz VERITAS Cluster Server Wizard
VRTScsga VERITAS Cluster Server Graphical Administrator
VRTSgab VERITAS Group Membership and Atomic Broadcast
VRTSllt VERITAS Low Latency Transport
VRTSvcsor VERITAS Cluster Server Oracle Enterprise Extension
VRTSvcssy VERITAS Cluster Server Sybase Enterprise Extension
VRTSperl VERITAS Perl for VRTSvcs

Cluster Name of your HA environment
Nodes Physical systems that make up the cluster
Service group Abstract container of related resources
Resource Cluster components (i.e. NICs, IPs, disk groups, volumes, mounts, processes, etc...)
Attributes Parameter values that define the resources
Dependencies Links between resources or service groups

Cluster Mgr Cluster Monitor : Log in, add clusters, change preferences
Cluster Mgr Cluster Explorer: Monitor systems, service grps, resources, attributes & dependencies
Cluster Mgr Log Desk : Monitor log messages received from engine, view GUI commands
Cluster Mgr Command Center : Build VCS commands and send to engine
LLT Low Latency transport provides fast kernel-kernel comm. & monitors network connx.
GAB Grp membership & Atomic Broadcast maintains a synch. state & monitors disk comm.
