Topology Maintenance |

The Storage Automated Diagnostic Environment's graphical storage area network (SAN) interface displays all fabric components and the state of those components. Fabric components include HBAs, switch ports, storage controllers, and disks, along with more specialized components such as fans, batteries, power, and volumes.

Note: Only HBAs connected to storage devices are displayed in Topology.

SAN agents collect counter information based on error messages and telemetry information. This information is then used in the Topology drawing to indicate link failures.
