NOTICE:
8 If you have a non-RAID SAS controller, remove the hard drive and swap its
drive bay location with another hard drive that is functioning properly.
If the problem is resolved, reinstall the hard drive in the original bay. See
"Installing a Hot-plug Hard Drive" on page 89.
If the hard drive functions properly in the original bay, the drive carrier
could have intermittent problems. Replace the hard-drive carrier. See
"Getting Help" on page 205.
If the hard drive functioned properly in another bay but does not function
in the original bay, the SAS/SATA backplane has a defective connector. See
"Getting Help" on page 205.
