3ware Serial ATA RAID Controller CLI Guide
/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.
Check for AENs with the alarms command
/cx show alarms [reverse]
. Using
the “reverse” attribute displays the most recent AEN message at the bottom 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.
/c
x
/bbu disable [quiet]
This command disables BBU detection on the controller. When disabled, the
controller ignores the existence of the BBU and will show 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.
