ServerNet II PCI Adapter and Switch Installation Guide
Figure G-1. A Configured Topology Example
This section analyzes the following four failures from each computer:
■
Failed computer HW-TB6-S12
■
Failed SwitchY
■
Failed link between computer HW-TB6-S12 and SwitchX
■
Port cables on computer HW-TB6-S03 swapped
Most ServerNet II SAN problems can be effectively isolated by running ServerNet II Online
Diagnostics (“Diagnostics “) from one computer. However, greater clarity of particularly
difficult problems might be derived by running Diagnostics from more than one computer and
then comparing the test results.
