# 772 The current array controller has one or more array accelerator batteries that have either failed or have insufficient voltage.

Array accelerator operations such as Expansion, Extension, and Migration are temporarily suspended until the batteries are charged or in the case of a battery failure, replaced. "

This problem with hdd or the controller battery? Or both that and another
It is necessary to change a disk and to replace the battery on the controller?

Hello,

I would raise a support call with HP on this if you have support.

I would also try to reseat the battery back cache module, its streight forward enough, just disconnect the battery and reconnect it, its a battery with a cable attached to the controller.

SOunds like the battery is faulty.

Hope it helps.
