This is probably a dumb question. I recently purchased a couple of refurbished HP SB40C storage blade for our HP Bladesystem c3000 enclosure. Each comes with an HP Smart Array P400/256MB SAS Controller and a 4.8V NI-MH cache raid battery.
The smart array utility warns me about a low charge on the battery for each storage blade. Could it be because they probably haven't been turned on for a while just sitting around in some storage room? I mean of course batteries will drain out on their own, but I'm assuming this is the case rather than a coincidence that both batteries are dead. So just what would most people assume in this case?
Also, how would it affect my array if I use the controller without batteries?
PS: I cant be sure because my enclosure doesn't have enough power supplies (arriving soon) to turn on 4 blades and hence possibly charge the batteries. I have to make a quick decision on whether the order new batteries ASAP or count on their simply needing to recharge.
Thanks!
