BBU Object Commands
BBU (Battery Backup Unit) Object Commands are commands that provide
information and perform actions related to a specific BBU installed on a
specific controller, such as /c0/bbu.
This object is only available on 9750 controllers and 9000 series controllers
on which a BBU is actually installed. (The BBU is not supported on 9590SE-
4ME.)
Syntax

/cx/bbu show attribute [attribute ...] where attributes are:
batinst|bootloader|cap|fw|lasttest|pcb|ready|serial|
status|temp|tempstat|tempval|volt
/cx/bbu show all (9000 series only)
/cx/bbu test [quiet] (9000 series only)
Warning: May take up to 24 hours to complete. Write cache
will be disabled during the test.

The command output indicates that the battery capacity was last measured on
01-Jul-2004. The battery is estimated to last for 72 hours from the last tested
date. In this example, the BBU unit is currently testing the battery. Both
voltage and temperature are normal. The BBU is not ready to backup the write
cache on the controller (due to the testing). (For complete information about
the BBU, see the user guide that came with your 3ware RAID controller).
Note : Features indicated as “9690SA only,” “9000 series,” or “9000 series SE/SA
only” also apply to 9750 controllers, with the following exceptions:
The BBU firmware version and bootloader version are not applicable for 9750.
Note: If the BBU is either not present or disabled, the following will be displayed
after the command //localhost> /c0/bbu show.
Error: (CLI:053) Battery Backup Unit is not present.
