Note on BBU charging and calibration
The BBU may be deeply discharged due to extended storage time and wrongly
show as bad or defective in the ServerView RAID Manager.
In this case, the BBU will automatically enter a trickle charge cycle for recovery.
This initial charge may take up to 8 hours before the BBU will initiate a
recalibration cycle.
Ê Enter the ServerView RAID Manager and check the current BBU status.
I
For further information, please refer to the "ServerView Suite RAID
Management" user guide, available online at
http://manuals.ts.fujitsu.com
Ê If the BBU is shown as bad or defective, do not power off the server node for
at least 8 hours to allow the charge and calibration cycles to finish.
Ê If the BBU status does not change after 8 hours, please try to initiate the
recalibration process manually using the ServerView RAID Manager.
I
If this procedure still does not fix the BBU status, please contact your
local Fujitsu customer service partner.
