Diagnostics Decision Chart

The diagram below shows in what situations you should run the various Diagnostics tests.
Figure F-1. Running Diagnostics Tests
NOTE: While Figure F-1 suggests you run the Echo Test from all nodes, we recommend that you only run
the test on the nodes associated with the SAN failure. This may isolate the failure without running the
Echo Test on each node.
