Problems During Bootup
The following sections describe problems you might encounter during Power On
Self-Test (POST) or during bootup sequence of the enclosure and explains how
to resolve those problems. POST shows problems related to the processor, logic,
and memory.
Nothing is displayed
on the terminal
emulator screen.
The probable cause of this
problem could be an
incorrect baud rate setting, a
bad RS-232 cable connection
or an incorrect cable type.
If the cable is properly connected,
ensure that the cable is a
null modem
type.
Screen is updated, but
will not respond to
keystrokes.
Improper setting.
Disable hardware flow control on the
terminal or terminal emulator.
Symptom
Solution
Controller failed the onboard
memory test (ECC Error).
When this failure occurs, it means the internal CPU memory
failed. Replace the controller to correct the problem.
One of the POST diagnostic
tests failed.
Replace the faulty controller.
The system hangs during a drive
scan.
Follow these steps to resolve the problem:
1 Check the enclosure(s) to make sure everything is
properly connected.
2 Remove and replace the drive that failed the scan.
3 If the enclosure(s) and the drive work properly,
replace the controller.
An Active-Active controller pair
always fails over after booting
up.
Verify the same SDRAM DIMM sizes are in both controllers.
Active-Active controllers require the same SDRAM DIMM
size. Verify that the firmware is the same for both
controllers.
Verify that the connector is not physically damaged.
