Hot-Plug SCSI Hard Drive LEDs
Each hot-plug SCSI hard drive has three LEDs located on the front of the drive. The
LEDs provide activity, online, and fault status for each corresponding drive when
configured as a part of an array and attached to a powered-on Smart Array controller.
Their behavior may vary depending on the status of other drives in the array. Use
Figure E-3 and Table E-3 to identify LED locations and functions.
CAUTION: Before removing a hard drive, refer to the HP ProLiant Servers
Troubleshooting Guide on the Documentation CD for information on hard drive
replacement.

off indicates no activity by the drive.
The second LED indicates online status (2), where flashing indicates an active
online condition and off indicates an inactive online condition.
The third LED indicates fault status (3) where flashing indicates fault-process
activity and off indicates a no-fault-process activity.
