Grid Summary

The Grid Summary panel is the first page displayed on the management interface when the IBM® TS7700 is online. You can use this panel to quickly assess the health of all clusters in the grid and as a starting point to investigate cluster or network issues.

This panel shows a summary view of the health of all clusters in the grid, including family associations, host throughput, and any incoming copy queue.
Note: If the accessing cluster is a stand-alone cluster the Cluster Summary panel is shown upon login.
