====== Policy Based HA (replace Hyperswap) ====== Storage partitions are used to implement a Policy-based High Availability solution.Partitions contain * volumes * volume groups * hosts * host-to-volume mappings. Within a partition: * All volumes are in volume groups. * Mappings can only be created between volumes and hosts in the same partition {{:storage:IBM_pbha01.png?300|}} You 'll apply a replication policy to the volume group and optionally a protection policy based on snapshotting, with or without safeguard.
