Re: battery reconditioning
Hi, form time to time, there appears some error / warning messages in console, which say this: Sep 28 00:13:40 dell kernel: aac0: **Monitor** Battery needs reconditioning. What is your question? It informs you you should change the battery used on the RAID hardware, so change the battery :) Hardware RAID has a system to delay the write when the disk is idled. The sectors to be written are kept in a temporary RAM and this RAM is powered by batteries. When there is a power failure, the battery should provide electricity to the hard disk, just long enough to write back the sectors that have been delayed. If the battery fails, these sectors will never be written. So if the battery is bad, replace the battery.

Some battery types benefit from an occasional deep discharge. http://support.dell.com/support/edocs/software/svradmin/1.9/en/stormgmt/battery.html ___ freebsd-questions@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-questions To unsubscribe, send any mail to freebsd-questions-unsubscr...@freebsd.org
