1.9.1.1 Step 1: Prepare the Disk Controller BBU for Removal

The method of removing the Disk Controller BBU depends on the Oracle Exadata Database Machine model.

On certain Oracle Exadata Database Machine X3-2, X4-2, and X4-8 database nodes, and Oracle Exadata Database Machine X3-2, X4-2, X3-8, and X4-8 storage servers, the BBU is remote mounted and does not require a system shutdown to be accessed. However you must still prepare it for removal from the RAID HBA to avoid the risk of data corruption to the disk volumes.

Note:

There is no remote mount BBU option for Oracle Exadata Database Machine X3-8 database nodes.
