You can create a local synchronization partition with a local disk on each CVM host after you set up the stateful failover system. Before you create the local synchronization partition, make sure the primary and backup CVM hosts meet the following requirements:
They are not added to CAS as CVK hosts.
They only have default storage pools.
They are not compute nodes of vStor or ONEStor.
They cannot access LUNs on FC or iSCSI storage devices. As a best practice, remove the cables connected to FC or iSCSI storage devices.
