Will there be any possible data loss of configuration information damage?<BR /><BR />Any ideas appreciated for this silly question.<BR /><BR />Cheers, Wed, 13 Sep 2006 07:46:20 GMT https://community.hpe.com/t5/proliant-servers-ml-dl-sl/what-if-raid-controller-battery-failed/m-p/3861988#M56946 Hunter1ok 2006-09-13T07:46:20Z https://community.hpe.com/t5/proliant-servers-ml-dl-sl/what-if-raid-controller-battery-failed/m-p/3861989#M56947 &gt;&gt;what would happen if the battery exhausts?<BR /><BR />SmartArray controller cache will be disabled and array performance degraded<BR /><BR />&gt;&gt;Will there be any possible data loss of configuration information damage?<BR /><BR />No !
