4. You can set the I/O groups that your host can access.
Important: The host objects must belong to the same I/O groups as the volumes that
you want to map. Otherwise, the host cannot see these volumes. For more information,
see Chapter 6, “Volume configuration” on page 287.
The IBM Storwize V5000 supports a maximum of four nodes per system. These nodes
are arranged as two I/O groups per cluster. Due to the host object limit per I/O group, for
maximum host connectivity, it is best to create hosts that use single I/O groups.
