10 12Gb/s Intel® RAID Controllers User Guide
Drive Roaming
Drive roaming occurs when the drives are changed to different ports on the same
controller. When the drives are placed on different channels, the controller detects the
RAID configuration from the configuration data on the drives.
Configuration data is saved in both the NVRAM on the RAID controller and on the drives
attached to the controller. This action maintains the integrity of the data on each drive,
even if the drives have changed their physical device ID.
Note: If you move a drive that is being rebuilt, the rebuild operation restarts; it does not resume
from the stopping point.
Follow these steps to use the drive roaming feature:
1. Turn off the power to the server and all drives, enclosures, and system components.
Disconnect the power cords from the system.
2. Open the host system by following the instructions in the host system technical
documentation.
3. Move the drives to different positions on the backplane to change the targets.
4. Determine the SAS target requirements.
5. Perform a safety check.
a. Make sure that the drives are inserted correctly.
b. Close the cabinet of the host system.
6. Reconnect the power cords to the system.
7. Turn on the power to the system.
The controller then detects the RAID configuration from the configuration data on
the drives.
Drive Migration
Drive migration is the transfer of a set of drives in an existing configuration from one
controller to another. The drives must remain on the same channel and must be reinstalled
in the same order as in the original configuration. The controller to which you migrate the
drives cannot have an existing configuration.
Note: Partial configurations, which include individual virtual drives, can be migrated.
Note: Drive roaming and drive migration cannot be supported at the same time.
Follow these steps to migrate drives:
1. Make sure that you clear the configuration on the system to which you migrate the
drives to prevent a configuration data mismatch between the drives and the
NVRAM.
