7.5.2 Notes on WSFC

This subsection provides notes on WSFC.

Organization of this subsection

(1) About starting and stopping SSO

If the SSO resource is active:

If the SSO resource is indicated as Online in the cluster administrator window, use the window to deactivate the SSO resource. Do not use the ssostop command to deactivate the SSO resource.

If the SSO resource is inactive:

If the SSO resource is indicated as Offline in the cluster administrator window, use the window to activate the SSO resource. Do not use the ssostart command to start the SSO resource.

(2) About the IP addresses in a cluster system

The IP address of the local host might not be registered in the hosts file if a DNS or another means is used for name resolution. In such a case, a link-local IP address assigned by APIPA might be set as the IP address. This link-local IP address might cause an SSO communication error. To prevent the error, make sure that all IP addresses used in a cluster system can be resolved to the host names of physical nodes.
