is in use.
Diskette-eject button:
Press this button to release a diskette from the drive.
Hard disk drive status LED:
On some server models, each hot-swap hard disk
drive has a status LED. If the status LED for a drive is lit continuously, that
individual drive is faulty. The interpretation of a flashing status LED depends on the
SCSI controller connected to the hot-swap drive, as follows:

When the drive is connected to the integrated SCSI controller with RAID
capabilities, a flashing status LED indicates that the drive is a secondary drive in
a mirrored pair and the drive is being synchronized.
v
When the drive is connected to an optional ServeRAID controller, a slowly
flashing (one flash per second) status LED indicates that the drive is being
rebuilt. When the LED is flashing rapidly (three flashes per second), it indicates
that the controller is identifying the drive.
