Figure 110. Battery Backup Page
The Battery Backup page appears when you choose Monitor > Battery
Backup on the menu bar. Use this page to determine whether a backup battery
is present, see details about it, and perform a battery test.
Battery Backup Unit. Indicates whether the BBU is present.
Firmware. Indicates the BBU firmware version.
Serial Number . Indicates the BBU serial number.
BBU Ready. Indicates if the BBU is able to backup the 3ware RAID
controller or not. If the BBU is “Ready”, write cache can be enabled on the
3ware RAID controller. When the status is not “Ready,” write caching is
automatically disabled on all units attached to the controller.
BBU Status. Indicates the status of the BBU. Possibly BBU statuses include
the following:
• OK . The BBU is functioning normally.
• Not Present . The BBU was not detected or is disabled. (The BBU can be
disabled using CLI.)
• No Battery . No battery pack is installed in the BBU.
• Testing . A battery capacity test is in process.
• Charging . The battery is being charged. Charging of the battery occurs
automatically if the battery voltage falls too low. This normally occurs
about once a week to top off the charge level; the process does not change
the BBU readiness state.
