7.2.3 Resource Operation

This section describes how to set resources Online/Offline individually.

Note

It is assumed that this function is used when you check the behavior of resources during cluster application configuration. Do not perform any business operations while cluster applications are partially Online.
If you want to carry out business operations without starting a resource, delete that resource from the cluster application. For instructions on deleting a cluster application, see "10.5 Deleting a Resource."
After using this function, restart the application by the following procedure before starting any business operation, and make sure that all resources become Online.
1. Stop userApplication.
```
# hvutil -f userApplication
```
2. Check that all resources controlled by userApplication are stopped.
```
# hvdisp -a
```
3. Start userApplication.
```
# hvswitch userApplication SysNode
```
4. Check that all resources controlled by userApplication are started.
```
# hvdisp -a
```
Stop cluster applications in scalable operation whenever you start/stop a resource with scalable configuration individually. After that, execute the operation on the cluster applications in standby operation that constitute the cluster applications in scalable operation.
For details, see "8.3 Managing resources" in "PRIMECLUSTER Reliant Monitor Services (RMS) with Wizard Tools Configuration and Administration Guide."
