Troubleshooting Your System
7
If you have the non-RAID SAS controller daughter card, 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 56.
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 147.
If the hard drive functioned properly in another bay but does not function in the original bay, the SAS
backplane has a defective connector.
See "Getting Help" on page 147.
