Dell H700 Controller, BBU present but not charging...?

  • 772

I have a new Dell R710 with a H700+BBU controller that is not charging. Last week when I was looking at performance stats (and trying to figure out why write policy had changed from write-back to write-through) I realized the BBU was not charged. The overall stats available through MegaCli appear to indicate the BBU is OK but it wont charge. I kicked off a manual learn cycle, waited a couple days, reseated the BBU, and nothing seems to get the BBU to a charging or charged state.

Any help is much appreciated.

  1. This is a new 710? Call up Dell, get them to ship you a new unit within your SLA. Swap drives into new unit, send old one back.

    Dell shipped me a new BBU, replaced it and now the battery state is charging. The issue was a bad BBU. controller is OK.

  3. If you have an operating system installed, there is a piece of software from Dell called OMSA (Open Manage Server Administrator). This can be used to do a plethora of different administrative functions not the least of which is a battery recondition function. This takes a bit but it might revive your dead battery. Hope this helps.
