Select a Host/Topology
| [ Back ] |
Use the Topology section to display a host-based topology and SAN-based
topologies.
To display the corresponding topology, select a host from the left
frame.
You can also select a TOPO name, as created in the Topology
Maintenance -> Merge Topologies section.
The icons shown in Topology Help symbolize the various storage devices
that Storage Automated Diagnostic Environment> monitors. Inside each storage device icon are boxes that
represent disks inside the arrays, ports, and 'other' components.
The 'other' category includes a variable set of boxes that represent
components (labeled L, M, P, V, F, B, P, and O) of the enclosures that
are monitored. 'Other' components include the following:
- Sun StorEdge T3 Array (T3): L=LUN, M=Midplane, P=Power, V=Volume
- Sun StorEdge Network FC Switch-8 and Switch-16 (Switch): F=Fan, P=Power, T=Temp
- Sun StorEdge A5000 Array (A5K): F=Fan, B=Backplane, P=Power
- Host: O=Other
Fibre Channel errors are represented by red links with the word 'fc' in red.
This means that CRC or ITW were found at either end of the link in red.
Fibre Channel errors are usually intermittent and do no represent a hard failure.
When a hard failure occurs, a switch port going offline for example, fibre channel
counters are ignored.
