244 Implementing the IBM Storwize V5000 Gen2 with IBM Spectrum Virtualize V8.1
7. You can set the I/O Groups that your host can access. The host objects must belong to
the same I/O groups as the volumes that you want to map. Otherwise, these volumes are
not visible to the host. See Figure 5-47.
Figure 5-47 Setting I/O groups
Note: The IBM Storwize V5000 supports a maximum of two nodes for each system.
The two 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.
