What the relationship of cimserver and serviceguard package

[songyong]

In a troubleshooting case ,  command cmrunpkg failed with log " cimserver failed"  in pkg.log. After i solve the cimserver problem, pkg could  run.

I thought that the running of pkg depend on the cimserver to monitor the environment of the system.

However, in another case the cimserver is skipped in startup, and the pkg can run without any warning or error mesg in log.

Question:

1.What the relationship of cimserver and MCSG package ?

2.How to explain the above two cases.

1.) cimserver produces various system monitoring information, which may be used by a Serviceguard package to determine if a package can run on a given node or not. However, a package is not required to make use of this information.

2.) My guess would be that in the first case, the package configuration included something that depends on cimserver, and in the second case, such a dependency did not exist.

Remenber that Serviceguard packages are very configurable. It is possible to create a Serviceguard package that contains no IP addresses, no shared VGs, no scripts nor services to run and no resource monitoring at all. Such a package would be of very limited utility: it would be a virtual object that would be guaranteed to be possessed by only one node at a time, but does nothing on its own.

To really answer your questions, it would be necessary to read the package configurations used in your specific cases to understand their requirements.
