1-14 Overview
Note: If you move a drive that is being rebuilt, the rebuild
operation will restart, not resume.
Follow these steps to use drive roaming:
Step 1. Turn off the power to the server and all physical disks,
enclosures, and system components. Disconnect the power
cords from the system.
Step 2. Open the host system by following the instructions in the host
system technical documentation.
Step 3. Move the drives to different positions on the backplane to
change the targets.
Step 4. Determine the SAS target requirements.
Step 5. Perform a safety check.
a. Make sure that the drives are inserted correctly.
b. Close the cabinet of the host system.
Step 6. Reconnect the power cords to the system.
Step 7. Turn on the power to the system.
The controller then detects the RAID configuration from the

Note: Drive roaming and drive migration cannot be supported at
the same time.
