Troubleshooting
Problem 13
After updating the Adaptec SCSI RAID controller firmware or BIOS and rebooting,
the adapter does not respond.
Solution 13
The update may have been unsuccessful. The controller is now in a state in which it
hangs the system during boot. If this happens, the parameters in the NVRAM can be
restored to their default settings using the following procedure:
1. Turn off power to the system.
2. Place a shorting jumper across pins 1 and 2 of P4 on the controller.
3. Power on the system and wait until the LEDs 3, 5, 7, and 8 on the controller
begin flashing.
4. Turn off power to the system and remove the jumper.
You can now reconfigure the controller using SMOR.
Problem 14
After updating the Adaptec SCSI RAID controller firmware or BIOS and rebooting,
LEDs 1 and 5 or 2 and 5 flash once per second.
Solution 14
These patterns indicate that the adapter startup code detected a firmware checksum
error or a flash error. Attempt the firmware update procedure again by using the
procedure in the following Problem description to recover from this condition.
