186 RAID Controller Batteries
The controller battery should be reconditioned when either of the following
occurs:
• The controller reports the battery state as Degraded. For more information
on the battery state, see Battery Properties.
• The controller generates event 2145 indicating that the battery needs
reconditioning.
For information on Alert Messages, see the Dell OpenManage Server
Administrator Messages Reference Guide at support.dell.com/manuals.
The battery recondition takes approximately 8 to 10 hours. During this time,
the battery is fully discharged and recharged. The battery holdover time is
reduced to zero (during discharge) and then restored as the battery is fully
charged. The write cache is disabled during the battery recondition resulting
in performance degradation.
To recondition the controller battery:
1
Expand the Storage tree object to display the controller objects.
2 Expand the controller object.
3 Select the Battery object.
4 Select Recondition Battery from the Available Tasks drop-down menu.
5 Click Execute .
NOTE: The Recondition Battery task is only available on controllers with NiMHi
batteries that are in Degraded state or that have generated alert 2145. For
information on Alert Messages, see the Dell OpenManage Server Administrator
Messages Reference Guide at support.dell.com/manuals. Some controllers do not
have batteries. Other controllers have lithium ion batteries which are automatically
reconditioned and therefore do not have a recondition task in Storage
Management.
