Chapter 4 Refresh

This chapter describe about the refresh(Learn Cycle).

1. Refresh

A RAID controller must measure correct capacity of battery. So, it discharges from the
condition of the filling charging and it recharges after that. This processing is called
"Refresh".

There  are  "initial  refresh",  "periodic  refresh",  "manual  refresh"  in  the  kind  of  the  refresh.
The  initial  refresh  is  the  refresh  to  run  operate  automatically  only  once  to  the  unused
battery. At first, the RAID controller charges the battery fully, and then discharges. Finally it
charges  the  battery  again,  and  refresh  completes.  For  the  periodic  refresh,  refer  to  "3.
Periodic refresh" in this chapter. For the manual refresh, refer to "4. Manual refresh" in this
chapter.

The refresh runs automatically just one time because the correct capacity is saved to a
BBU.

It is not able to check whether the battery is on the way of refresh or not. You can
understand that the refresh is running until the Cache Mode changes to "Write Back".
