M.9.9 Setting up the Host OS failover function used in the PRIMEQUEST KVM environment

Details on incompatibilities

When using the Host OS failover function in the PRIMEQUEST KVM environment in PRIMECLUSTER 4.4A00, it is required to set the shutdown facility on the Host OS (node).

Changes

Before upgrading [PRIMECLUSTER 4.3A20]

When using the Host OS failover function in the PRIMEQUEST KVM environment, the shutdown facility was set on a guest OS (node).

After upgrading [PRIMECLUSTER 4.4A00]

When using the Host OS failover function in the PRIMEQUEST KVM environment, the setting of the shutdown facility is required not only on the guest OS (node) but also on the Host OS (node). This will enable you to reduce the cluster failover time between guest OSes if a failure occurs on the Host OS.

For details on the setting, see "5.1.2.5.6 Setting up the Host OS Failover Function to the Host OS (PRIMEQUEST only)."

Note

None.
