controller LEDs
When the power-up sequence is complete, viewing the LEDs can
help you determine the operating status of the controller. These
LED patterns are also useful for troubleshooting. Refer to
Appendix C
for more information on interpreting LED patterns.
cache status LEDs
Cache failure information is recorded in the controller error log
and can be viewed using the Event Log window in Storage
Manager.
cache status LEDs –
Adaptec 2400A/3200S/
3400S only
The following LEDs on the Adaptec RAID controller indicate the
status of the onboard cache RAM:
■
ECCEN (ECC Enable)—Lit (green) when the installed
cache module has ECC.
LED
Function
1
Indicates that controller is working and interrupts are enabled.
During controller activity, this LED flashes four times per
second.
2
Indicates the occurrence of a nonmaskable interrupt (NMI) to
the I/O processor on the controller.
3
Indicates the controller’s internal operating system is in its idle
loop.
4
Indicates that the controller’s internal operating system is
processing an interrupt.
5
Reserved for future use.
6
Indicates that the cache controller is using Direct Memory
Access (DMA) to perform a data transfer.
7
Indicates the controller is generating parity information for a
RAID 5 array (hardware XOR).
8
Indicates that there is a command on the peripheral bus.
IRQ
Indicates the controller activated an interrupt on the host PCI
bus.
