LSI 25083 manual Drive Migration

Page 33

Follow these steps to use drive roaming:

Step 1. Turn off power to the server and all 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.

1.6.8Drive 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, including 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:

Step 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.
