b. Remove the system cover.
c. Check the SCSI cable connection to the SCSI host adapter.
The SCSI cable may be connected to the internal SCSI host adapter on the system board or a SCSI host adapter installed in an expansion slot.
7. Partition and logically format the hard-disk drive. If possible, restore the files to the drive.
To partition and logically format the drive, see the documentation for the system's operating system.

Troubleshooting a RAID Controller Card
Your system may contain an optional RAID controller card. If you encounter problems with a controller, see the RAID controller's documentation for detailed
information on troubleshooting the RAID controller.
NOTE: If the SCSI cable is connected to the SCSI channel A only, all six hard-disk drives are controlled. If both SCSI channels A and B are connected,
the SCSI channel A controller controls hard-disk drives 0 through 2 (SCSI ID 0-2) and the SCSI channel B controller controls hard-disk drives 3 through
5 (SCSI ID 3-5).
WARNING: Before you perform this procedure, you must turn off the system and disconnect it from its power source. For more information, see
"Safety First—For You and Your System."
