Configuration of NVRAM and drives mismatch (normal mismatch).

Configuration of NVRAM and drives mismatch (normal mismatch).

After a harddisk crash the NVRAM can be screwed up of a Dell PERC controller. To set the configuration from the disks to the nvram, do the following:

1. Run the BIOS utility (CTRL+M) to see the configuration,
2. Select Configure,
3. View/Add Configuration,
4. Select the desired Configuration,
5. If this is the configuration you want to use, escape and select Save.

After restarting the nvram has the latest config written to it.

  1. thank you, it worked like a charm – so instant. i copied the configuratiion from the HDD and hooray, i got the drives online and no more NVRAM errors.

  2. This is exactly what we needed when this error popped up after rebooting our main fileserver this morning. Thanks!

  3. RESULT: Worked OK on Dell poweredge 1800 with PERC 4/sc controller.

    CAUSE: The cable was disconnected from controller and then the error with the mistach appeared.

    P.S. The beeping is so annoying and I couldn’t find the way to turn it off – so I had to remove the controller while i was testing RAM after server crash. Afterwards I connected the controller and the above solution worked. I used the config form the drives – they were showing ONLINE and the nvram was showing FAIL.

  4. Thanks from me too – Annoyingly I had to drive 15 miles to find this out – no ip kvm here. The save option wasn’t obvious when I first went into the config screen.

  5. Thanks for the SAVE tip. Like Andy said, the SAVE prompt is not front & center, it is displayed in the upper right corner after leaving the VIEW CONFIGURATION screen. If you enter the View Configuration screen, and it prompts you to choose between Controller or NVRAM, you realize the NVRAM has no configuration saved in it. After you save, and you try to view config again, there will be no prompt to choose the view. This indicates config was written to NVRAM properly. You can reboot and it should find your boot drive.
