7.4.2 Corrective Action in the event of the LEFTCLUSTER state when the virtual machine function is used

If the host OS becomes the panic state or hangs up when the virtual machine is used, the LETCLUSTER state may occur. This section describes the corrective actions in this case.

7.4.2.1 When the host OS becomes the panic state

1. When the host OS becomes the panic state, and the host is restored after that, go to the step 3.

2. Check the state of the host OS and restore the host OS.

3. If a failed node (guest OS) is in the LEFTCLUSTER state, perform the procedure in "5.2 Recovering from LEFTCLUSTER" in "PRIMECLUSTER Cluster Foundation (CF) Configuration and Administration Guide."

4. Check that the node joins the cluster.

7.4.2.2 When the host OS hangs up

1. Check that the node (guest OS) is actually stopped. If it is running, stop it.

2. Check the state of the host OS and restore the host OS.

3. If a failed node is in the LEFTCLUSTER state, perform the procedure in "5.2 Recovering from LEFTCLUSTER" in "PRIMECLUSTER Cluster Foundation (CF) Configuration and Administration Guide."
