Upgrading Your System 4-9
Determining Drive Status
Status LEDs arranged in sets of three below each of the two hot-swapping bays
monitor the status of each drive. When a yellow LED is on continuously, it is
okay to hot-swap (remove and replace) a bad drive with a good one. You DO
NOT need to shut down the server to hot-swap a drive. Table 4-1 provides a
description of SCSI drive status LEDs.

The hot-swap controller is responsible for turning the yellow drive fault LED on or off according to the states
specified by commands received via SAF-TE and IMB.
1.
Look at the yellow LEDs below the hot-swapping bays to determine which
drive is bad.
2.
Push on the drive carrier latch of the bad drive, and while grasping the
handle, pull the assembly toward you to disengage the drive from the
backplane connector.
3.
Before moving the drive any further, wait 30 seconds. This elapsed time
allows the drive platter to stop rotating.
4.
Carefully slide the assembly out of the bay, and place it on an antistatic
surface.
5.
Orient the new carrier and drive assembly in front of the hot-swapping bay
guide rails so that the metal fingers of the perforated metal bracket attached
to the carrier are facing up. Make sure you correctly place the carrier into
the guide rails to avoid damage.
6.
While grasping only the drive carrier handle, firmly push the assembly into
the bay until the driver carrier latches.
