Disk Drive LEDs
There are two LEDs on each Drive Carrier. They report the presence of a disk
drive, activity of the drive, and the drive’s current condition.
Figure 11.VessJBOD disk drive carrier LEDs
If there is a disk drive in the carrier, the Power/Activity LED displays green. If not,
the Power/Activity LED remains dark. The Power/Activity LED flashes during
drive activity.
The RAID subsystem controls the Disk Status LED behavior. With a VessRAID,
the LED displays green when a drive is configured.
I/O Module LEDs
When boot-up is finished and the VessJBOD subsystem is functioning normally:
• Fan LEDs display green continuously.
• The I/O Module LED displays green, and flashes green for activity.
• SAS port LEDs flash green when there is activity.
