The Power/Activity LED flashes during drive activity.
The RAID subsystem controls the Disk Status LED behavior. With a VessRAID,
the Disk Status 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.
