The following subsections describe how to remove or install hard-disk drive carriers in
the storage system's drive bays.
If the storage system is connected to a Dell PERC 2, Dell PERC 2/DC, Dell PERC 2/
SC, or Dell PERC 3/DI host adapter card or another host adapter card approved by Dell
for hot-pluggable drives, you can remove and insert SCSI hard-disk drives while the
storage system is running.
Before attempting to remove or insert a drive while the storage system is running,
see the documentation for the Dell PERC 2, Dell PERC 2/DC, Dell PERC 2/SC, or Dell
PERC 3/DI host adapter card to ensure that the host adapter is configured correctly to
support drive removal and insertion.

The three light-emitting diode (LED) indicators at the top of the hard-disk drive carriers
provide information on the status of the hard-disk drives. The storage system firm-
ware controls the drive online and drive fault indicators, while the drive itself usually
controls the activity indicator.
Table 6-1 lists the various drive indicator patterns. Different 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 pre-
pared for removal" pattern appears, followed by the "drive ready for removal" pattern.
After the replacement drive is installed, the "drive being prepared for operation" pat-
tern appears, followed by the "drive online" pattern.
