I would update the firmware of the controller. Once you do, there will be a foreign config menu in the controller's BIOS. You can download the firmware here. <ADMIN NOTE: Broken link has been removed from this post by Dell>You will need to make a set of floppy disks that you will boot to. If you do not have a floppy drive, you may need to call tech support cause I think they will have a ISO file that you can use to boot to a CD.
PERC 5 I Data recovery
Please be aware this is not a guarantee of data recovery and if the data is truly vital you may wish to contact a data recovery service.5. Press <CTRL><E> during POST to enter the BMC.6. Scroll down to System Event Log Menu and press <Enter>.7. Select View System Event Log and press <Enter
8. Determine the order in which each disk went offline. Use the right and left arrow keys to scroll through the SEL log.
NOTE:It is imperative to force the first disk to fail offline immediately after the retag is complete in order to keep from propagating data corruption. In the following images, disk 2 was the first disk to go offline.
9. Reboot the system and press <CTRL><R> to enter the PERC 5 BIOS.
10. Scroll down to the failed virtual disk and press <Enter> to verify the configuration of the virtual disk and which members are missing.
NOTE:The text of the failed virtual disk will be red. NOTE:Make a note of the RAID type, members of the array, size of the array, and element size. Element size is only used for RAID 5 and RAID 50 on the PERC 5. These setting will be required to recreate the identical virtual disk during the retag.
11. Select the failed virtual disk and press <F2>. Scroll down to Delete VD and press <Enter>.
12. Press <Enter> with OK selected to confirm the delete.13. Scroll up to the controller and press <F2>. Scroll down to Foreign Config, press the right arrow and press <Enter> on Clear.

Also make sure you are selecting the physical disk in the same order as they were in step 11. Notice the # column by each physical disk.
17. Press <Enter> to acknowledge that it is recommended to initialize all newly created logical disks. CAUTION:Initializing a disk erases all data. The retag procedure is designed as a effort to recover data. Re-tagged disks should not be initialized. 18. Scroll down to Physical Disks, press the right arrow key, then scroll down to the disk that went off line first and press <Enter>.
19. Scroll down to Force Offline and press <Enter>.
20. Press <Enter> with OK selected to confirm the force offline.21. Pull the disk out that was just forced offline and then reinsert the disk to start a rebuild. NOTE:If this does not start the rebuild, try creating the drive as a Hotspare. 22. Verify the rebuild has started and completes.23. Verify the logical drive is now healthy.
24. Boot to the OS and verify the data is present on the re-tagged disk.
