/cx/bbu test [quiet]
The /cx/bbu test command starts the battery capacity test. The test can 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. After the test is completed successfully and the BBU status returns
to OK, the write cache is re-enabled.
Asynchronous Event Notification (AEN) messages are also generated by
controllers to notify you 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 lists 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.)
/cx/bbu enable
The /cx/bbu enable command enables BBU detection on the controller. If the
BBU is Ready, the controller utilizes BBU functionality in the event of a
power failure.
/cx/bbu disable [quiet]
The /cx/bbu disable command disables BBU detection on the controller.
When disabled, the controller ignores the existence of the BBU and shows
that no BBU is installed even if a BBU is physically attached.
Note: Once started, the test can not be terminated before it completes. Write
cache cannot be enabled until the test completes.
