/c x /bbu show all
This command shows the current settings of all BBU-related attributes: ready,
status, batinst, lasttest, volt, temp, cap, serial, fw, pcb, bootloader.
Example:
//localhost> /c1/bbu show all
/c1/bbu Firmware Version = BBU: 2.00.00.023
/c1/bbu Serial Number = L319003B7460719
/c1/bbu BBU Ready = Yes
/c1/bbu BBU Status = OK
/c1/bbu Battery Voltage = OK
/c1/bbu Battery Temperature = OK
/c1/bbu Estimated Backup Capacity = 241 Hours
/c1/bbu Last Capacity Test = 22-Jun-2008
/c1/bbu Battery Installation Date = 20-Jun-2008
/c1/bbu Bootloader Version = BBU 0.02.00.002
/c1/bbu PCB Revision = 65
//localhost>
/c x /bbu test [quiet]
This command starts the battery capacity test. The test may take up to 24
hours to complete. During the test, the BBU is not capable of backup
operation and the write cache of all units attached to that controller is
disabled. Once the test is completed with no error and the BBU status returns
to OK, the write cache will be re-enabled.
AEN (Asynchronous Event Notification) messages are also generated by
controllers to notify the user of the command status.
You can check for AENs with the controller alarms command
/cx show alarms [reverse] or with the commands /cx show events [reverse]
or /cx show AENs [reverse]. Using the “reverse” attribute displays the most
recent AEN message at the top of the list. (For a list of all AENs, see the user
guide that came with your 3ware RAID controller.)
/c x /bbu enable
This command enables BBU detection on the controller. If the BBU is Ready,
the controller will utilize BBU functionality in the event of a power failure.
Note: Once started, the test can not be terminated before it completes. Write
cache cannot be enabled until the test completes.
