Troubleshooting Hard Drives
CAUTION: This troubleshooting procedure can destroy data stored on the hard
drive. Before you proceed, back up all the files on the hard drive, if possible. Refer
to the RAID controller documentation for rebuilding and servicing a RAID array.
1 Run the appropriate controllers test and the hard drive tests in system
diagnostics. See "Running System Diagnostics" on page 325.
If the tests fail, go to step 3.
2 Take the hard drive offline and wait until the hard-drive indicator codes on
the drive carrier signal that the drive may be removed safely, then remove
and reseat the drive carrier in the blade. See "Hard Drives" on page 267.
3 Restart the blade, enter the System Setup program, and confirm that the
drive controller is enabled. See "Integrated Devices Screen" on page 144.
4 Ensure that any required device drivers are installed and are configured
correctly.
NOTE: Installing a hard drive into another bay may break the mirror if the mirror
state is optimal.
5 Remove the hard drive and install it in the other drive bay. See "Hard
Drives" on page 267.
6 If the problem is resolved, reinstall the hard drive in the original bay.
If the hard drive functions properly in the original bay, the drive carrier
could have intermittent problems. Replace the drive carrier.
7 If the hard drive is the boot drive, ensure that the drive is configured and
connected properly. See "Configuring the Boot Drive" on page 269.
8 Partition and logically format the hard drive.
9 If possible, restore the files to the drive.
If the problem persists, see "Getting Help" on page 361.
