Using the diagnostic hardware
The DS4400 storage server comes with a wrap-plug adapter and LC coupler. The
wrap-plug adapter and LC coupler are used to identify Fibre channel path
problems. The loopback and sendEcho tests are described in the IBM TotalStorage
DS4000 Problem Determination Guide .
Symptom-to-FRU index
The Symptom-to-FRU index (Table 41) lists symptoms and the possible causes. The
most likely cause is listed first.
The problem determination (PD) maps found in the IBM TotalStorage DS4000
Problem Determination Guide provide you with additional diagnostic aids.
