Topology Maintenance Task Flow

Task
Description
For Instructions
  • Creating a topology snapshot.
  • Viewing topology error details.
Request topology snapshots from each host and create a master snapshot.
  • Displaying a merged topology
  • Adding a new topology
  • Deleting a topology
Merge an arbitrary set of hosts and create a custom topology.
  • Comparing two topologies
Display archived topology information of the selected host or of a previously-configured selection of multiple hosts.
  • Creating multi-level topologies
Create custom groups of topology information.

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 switch ports, storage controllers, and disks, along with more specialized components such as fans, batteries, power, and volumes.

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.


Note -

Brocade switch configurations using segmented loop (SL) zones can be monitored and diagnosed, but the topology views do not show connections between devices.


To view a topology, you must first execute the ras_install command to start the Storage Automated Diagnostic Environment services, then run the config_solution command to create the topology, find the devices, and run the agents.
