Controller Error Conditions
The HSZ70 RAID controller Operator Control Panel (OCP) contains the
following switches and indicators (see Figure 4–3):
•
Controller reset switch with an embedded green status LED
•
Six amber SCSI bus status LEDs
Figure 4–3 Typical Controller OCP Display
The green controller LED indicates the status of the controller. This LED flashes
constantly once the controller initialization process is complete and the software
is functioning. Pressing this switch resets the controller.
The amber port LEDs are OFF when the bus is functioning properly. A port LED
that is ON or FLASHING indicates that a device on the bus is not functioning
properly.

Storage Device Fault Notification
The storage device SBBs two front panel LEDs display the status of the drives
using one of three possible states (ON, OFF, or FLASHING). The green Device
Activity LED is ON or FLASHING when the SBB is active (processing data).
The amber Device Fault LED is either ON or FLASHING to indicate an error
condition or configuration problem. Table 4–5 lists the SBB LED display
combinations and the corresponding drive status.
CAUTION
Removing a storage SBB when the Device Activity
LED is ON or FLASHING can cause the loss or
corruption of data.
