For LSI 3ware controllers only, you will need to run the dumpall utility and provide the output to LSI technical support. Instructions are provided below.

  2. Extract the contents of the dumpall archive to a blank floppy (or USB device).
  3. Remove all 3ware controllers from the system except the 3ware controller with the array for which you are trying to repair.
  4.  Boot to DOS.
    • You must boot to 16 bit DOS for low level hardware access to the array data.

      If you don't have a DOS bootable floppy, you can download a program to create a DOS bootable diskette (e.g. DOS 6.22, dos622.exe) from LSI PreBoot USB and CD package: Article ID 1211161499804
       , or create your own USB DOS boot. bootable USB device

      You cannot run dumpall in Windows, Linux, FreeBSD, or MacOS.
    • Insert the floppy diskette (or USB device) with the extracted contents of dumpall and type dumpdcb.bat. Dumpall takes about two minutes to run.
      If you have trouble running dumpdcb, refer to KB:

Cause of Data Loss

Data loss can result from many causes. These can include virus attacks, system malfunction, or human error in the handling or installation of the drive.
LSI Corporation highly recommends that users take standard measures to protect their data, the most important of which are frequent and regular backups, and diagnostic checks of your drives. LSI Corporation does not warrant any form of data loss.

Data Loss Prevention Tips

1.   Always back up, test your backup and keep current copies of important data offsite.

2.   Exit programs before shutting down your computer to avoid data loss and program corruption.

3.   Use high quality surge protectors or line conditioners with all computer equipment.

4.   Turn off peripheral devices after shutting down the computer, not while the disk is active 鈥?this may cause directory damage.

5.   Test your backup before reformatting your drive. If you use tapes, be sure you are familiar with the backup software before archiving important data.

6.   Power down before moving a drive.  When transporting a drive, prevent jostling by using a padded container.

7.   Allow sufficient space around the drive's cooling vents. Remove books, papers, etc., which might block airflow.  Do not put the drive on carpeting.

8.   Avoid rapid temperature changes.  As a general rule, if you are comfortable, the climate is appropriate for the drive. If the drive was previously in a very cold environment, allow your drive to warm up to room temperature before operating.

9.   Use software utilities with extreme caution. In case of severe corruption or physical damage this may make the problem worse.

10.   Power down immediately if your drive makes unusual noises. These sounds may indicate a mechanical problem that could ultimately result in total data loss.

When Disaster Strikes:

  • The first recovery attempt is always the BEST recovery attempt.
  • If you've lost critical data, data recovery service is your best and safest option.
