Operating the UltraSCSI Enclosure
UltraSCSI RAID Enclosure 2–17
Removal of a disk drive SBB device is automatically sensed by the
array controller.
When installing a replacement device in a configured subsystem, the
array controller ensures that the replacement device type is identical
to the one removed. Only after establishing complete compatibility
can the array controller start configuring the disk drive SBB. As part
of the configuration process, the array controller will restore all data
that was on the original disk.
Disk Drive Status LEDs
Each disk drive SBB has two LEDs that display its operating status
(Figure 2–6). The green device activity LED (C
ALLOUT
1) is O
N
or
F
LASHING
whenever the disk drive SBB is active.

The amber device fault LED (C
ALLOUT
2) F
LASHES
whenever the
array controller detects that this device has an error condition. This
LED also F
LASHES
when the array controller issues a locate
command. This LED is only O
N
or F
LASHING
when there is a device
malfunction, except when a locate command is issued.
