Drive Migration

channels, the controller detects the RAID configuration from the
configuration data on the drives.
Note:
In a clustering environment, drive roaming is supported
within the same channel only.
Configuration data is saved in both the NVRAM on the RAID controller
and on the physical drives attached to the controller. This action
maintains the integrity of the data on each drive, even if the drives have
changed their target ID.
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 all power to the server and all physical drives,
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
configuration data on the drives.
Drive migration is the transfer of a set of physical 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.
