Running SCF Remotely
Running SCF Remotely
The Subsystem Control Facility (SCF) provides commands that display general
information about the ServerNet Cluster subsystem. Because the view of a ServerNet
Cluster can change significantly from one node to another, you should gather data at
each node by using SCF and the TSM client software, then compare the information.
In the case of SCF, you can compare information by logging on to a remote TACL
process and then running SCF at the remote node. In the case of the TSM client
software, you can compare information by logging on to the system console for each
node in the cluster. Or, if a TSM dedicated LAN or a public LAN is available that links
multiple nodes, you can log on to any member node from the same system console.
Quick Reference: SCF Commands for Monitoring a ServerNet
Cluster
Table 5-1 lists SCF commands that can be used to gather information about a
ServerNet Cluster.
Note. For SCF changes made at G06.21 to the SNETMON and SANMAN product modules
that might affect management of a cluster with one of the star topologies, see Appendix I,
SCF Changes at G06.21.
