3.3 Disposing of Battery Backup Units
3.4 Transferring Cached Data from a Failed Controller
3-14
WARNING: Do not damage the battery pack in any way. Toxic
chemicals can be released if it is damaged.
The material in the battery pack contains heavy metals that can
contaminate the environment. Federal, state, and local regulations
prohibit the disposal of rechargeable batteries in public landfills. Be sure
to recycle the old battery packs properly. LSI reminds you that you must
comply with all applicable battery disposal and hazardous material
handling laws and regulations in the country or other jurisdiction where
you are using the BBU.
If you are using a MegaRAID controller with an iTBBU03 BBU, and if the
RAID controller fails when there is data in the cache that has not been
written to disk, you can save the data by removing the BBU from the
failed RAID controller and installing it on a new MegaRAID RAID
controller. For the data to be saved, the following conditions must be
met:
•
The new RAID controller on which you install the BBU must be the
same model as the failed RAID controller.
•
The replacement RAID controller must have a cleared configuration.
•
The new RAID controller must be connected to the same disk drives
as the original configuration.
Follow these steps to use the transportable BBU to transfer cached data
from a failed controller to a new controller:
Caution: Be sure to ground yourself before touching the RAID
controller and the transportable BBU.
1. Turn off the power to the computer system and disk drives.
2. Remove the failed RAID controller from the system.
3. Remove the transportable BBU from the failed RAID controller.
4. Install the transportable BBU on the replacement RAID controller.
