Scsi Hard-Disk Drive Indicator Patterns; Removing A Scsi Hard-Disk Drive With The System Running; Table 6-1. Scsi Hard-Disk Drive Indicator Patterns - Dell 6100 User Manual

Before attempting to remove or insert a drive while the
system is running, see the documentation for the Power-
Edge Expandable RAID Controller host adapter to ensure
that the host adapter is configured correctly to support
drive removal and insertion.
CAUTION: Removing and installing SCSI hard-
disk drives with the system running is not
supported for systems without a PowerEdge Expand-
able RAID Controller host adapter. Removing a drive
in this situation will result in a loss of data.

CSI Hard-Disk Drive Indicator Patterns
The three light-emitting diode (LED) indicators adjacent
to each of the six SCSI hard-disk drive bays provide
information on the status of the SCSI hard-disk drives.
The SCSI backplane firmware controls the drive online
and drive fault indicators, while the drive activity indica-
tor is usually controlled by the drive itself. Refer to
Figure 1-1 for the location of these indicators.
Table 6-1 lists the various drive indicator patterns. Differ-
ent patterns are displayed as drive events occur. For
example, in the event of a hard-disk drive failure, the
"drive failed" pattern appears. After the drive is selected
for removal, the "drive being prepared for removal" pat-
tern appears, followed by the "drive ready for removal"
pattern. After the replacement drive is installed, the
"drive being prepared for operation" pattern appears, and
then the "drive online" pattern appears.

Removing a SCSI Hard-Disk Drive With
the System Running
Remove a SCSI hard-disk drive as follows:
1. Wait until the drive status indicators adjacent to
the drive bay signal that the drive can be removed
(see Table 6-1).
If the drive has been online, the three drive indica-
tors will flash sequentially as the drive is powered
down. When all three indicators stop flashing, the
drive is ready for removal.
2. Release the carrier by pulling down the plastic
drive handle. Slide the carrier toward you until it
is free of the drive bay.
Make sure the keylock is unlocked so that the hard-
disk drive is not locked in place (see Figure 6-2).
When the drive is in use, you may want to use the
keylock to prevent accidental or unauthorized
removal.
