Interpreting drive status LEDs
The library reports all drive issues that can affect customer operations. In addition to examining
library reports, you should observe drive sled link LED and status LED activity.
Figure 27 (page 212) shows the locations of the status LEDs and the FC link LED on the rear of a
drive sled.
