Upgrading Your System
!
Always install a disk carrier tray in an empty disk drive bay to maintain
proper cooling.
!
If an individual SCSI 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 ground
any unpainted metal surface
on your
system when handling parts.
Note:
Swap SCSI 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
.
!
CAUTION
D
rive manufacturer's caution against moving a disk drive
that is still spinning because of possible damage to the
drive.
