The hard disk S-ATA address assignment is:
■
Always install a disk carrier tray in an empty disk drive bay to maintain proper
cooling.
■
If an individual SCSI or S-ATA drive activity/fault LED (amber light) is on
steadily, this indicates that the drive has been flagged as faulty by the RAID host
controller. Follow the procedure described in this section to remove the faulty
drive and swap in a good one.
Note:
ESD can damage disk drives, boards, and other
parts. This system can withstand normal levels of environmental
ESD while you are installing SCSI hard drives. However, we
recommend that you do all procedures in this chapter only at an
ESD workstation or provide some ESD protection by wearing
an antistatic wrist strap attached to chassis groundæany
unpainted metal surfaceæon your system when handling parts.
Note:
Swap SCSI or S-ATA drives without turning off
power.
This is one of the few system procedures that is safe to
do with the system power left on. This is true only if a
Redundant Array of Independent Disks (RAID) controller
module is installed and an appropriate RAID level; is chosen
and only for the drive/carrier assemblies in the hot-swap bays,
not for drives in any other bays.
