Which Serviceguard script file invokes the ECM or NFS Toolkit script?
-
Cluster configuration script
-
Package configuration script
-
Package control script
-
Cluster control script
Package control scripts in Serviceguard are responsible for starting and stopping packages, and they invoke toolkit scripts (like ECM or NFS) as part of these operations. Cluster configuration scripts set up the cluster itself, and cluster control scripts manage cluster-level operations rather than package-level toolkit integration.
In HP Serviceguard, the Package Control Script is the script that Serviceguard actually invokes at runtime to start/stop a package's resources, and it's responsible for calling out to toolkit-specific scripts (like the ECM — Enterprise Cluster Master toolkit — or NFS Toolkit scripts) to bring application-specific resources up or down. The Cluster Configuration Script and Package Configuration Script are used earlier, at setup/definition time, to generate the ASCII configuration that's applied to the cluster — they don't execute at runtime and don't invoke toolkit scripts. The Cluster Control Script (cluster-level heartbeat/membership management) operates at a different scope than individual package resource toolkits. Only the Package Control Script is the runtime entry point that calls toolkit scripts.
