This procedure describes how to identify a faulty drive using the fault LEDs on the drive.
You can also use the diskinfo(1M) command to identify the slot in which a particular drive is installed. Refer to Servers Administration and to the SPARC T5-1B Server Module Product Notes for more information.
When the amber drive Service Required LED on the front of a drive is lit, a fault has occurred on that drive.
See Drive LEDs.
