Thanks to my college Michael for this procedure.
I have a question regarding a similar issue.
On a ML570 G3 I have just aquired at auction, using the HP Smart Array 6400, I recieve the message same message string:
“Array Accelerator will be reenabled when batteries reach full…”
What is a reasonable time frame that one should exspect for this “Charge to Full” to complete. If you are still getting this message is it indicative that the battery will take a full charge at some point, or is it possible that it may not and needs replacement?
