NVRAM Reset

Adaptec RAID controllers retain their setup parameters even when
powered off. These parameters are stored on the controller in an area
of nonvolatile memory (NVRAM). There is a possibility that,
through improper configuration, the controller can be put into a
state where it hangs the system during start. If this happens, the
parameters stored in the NVRAM can be restored to their default
settings by following these steps:
Note: The 2000S and 2005S controllers do not have an
NVRAM reset jumper. Use SMOR's Default command or
RAIDUtil's -X command to reset the NVRAM.
1
Power off the system.
2
Install a jumper on the NVRAM reset jumper connector. Refer
to Appendix A
3
Power on the system and wait until the LEDs 3, 5, 7, and 8 on
the controller begin flashing.
4
Power off the system and remove the jumper.
5
Restart the system. If the system restarts normally, the
controller can now be configured using SMOR or Storage
Manager.
If the system fails to start, refer to
information.
