I just recently replaced a bad disk, but I did so incorrectly. Being the smart person I am, I just replaced the disk without unassigning the previous one. The disk I replaced the bad one with was being used on a previous FAS2040 which is no longer being utilized, so it was assigned differently. The next step I took was assigning the new disk to the filer, but in turn received a "Disk shelf fault. Disk shelf configuration error. Any help on this matter would be GREATLY appreciated!
