Driver updates for the 3ware RAID controller will be available from 3ware as
RPMs.
The following steps describe how to update the 3ware driver under VMware.
Warning:
Backup your original driver before updating in case you need to revert
back to it. However, you will not be able to revert back to the original driver if you
are booting from that unit.
Note:
If you wish to revert to a version of the driver that is older than the one
presently installed, you will first need to uninstall the present driver. For details, see
"Uninstalling 3DM Software on VMware" on page 334.

The Battery Backup Unit (BBU) is an add-on card that can be attached to
most 3ware 9000 RAID controllers to supply power from a battery pack in the
event of a system power loss. This allows the controller to use write-caching
for optimal performance and to preserve data in the event of a system power
failure. When fully charged, the battery preserves the contents of the cache
memory for up to 72 hours. When power is restored, the cached write data is
written to the disks.
The 9650SE can use the BBU-Module-03 or BBU-Module-04. The 9690SA
uses BBU-Module-04. For a list of 3ware RAID controllers and compatible
BBU modules, see http://www.3ware.com/KB/article.aspx?id=15008.
You can see information about a battery backup unit attached to your
controller in both 3DM 2 and 3BM.
