For details on functions for managing PRIMECLUSTER system operations, see "Chapter 7 Operations."
Note
When you configure the cluster system between guest OSes on a single ESXi host, an automatic switchover occurs only for an application error on guest OSes. Since an automatic switchover does not occur when a guest OS error occurs, stop the guest OS in which an error occurs and manually switch the cluster application by using hvswitch.
When the hvswitch -f command is executed to start or switch the cluster application, the following message is output and starting or switching of the cluster application may fail.
ERROR: Forcibly switch request denied, unable to kill node <SysNode name>This message is output when the node displayed as <SysNode name> is in the LEFTCLUSTER state. Perform the procedure in "5.2 Recovering from LEFTCLUSTER" in "PRIMECLUSTER Cluster Foundation (CF) Configuration and Administration Guide." After that, start or switch the cluster application.
Do not perform "Suspend operation" for the virtual machine on which the cluster is running. If "Suspend" is performed by mistake, an operation may not switch automatically. In this case, power off the virtual machine on which "Suspend" is performed, and then switch the operation manually.
