一、检查电池状态步骤：

OS/400 R52M0及以前：

进入SST，然后选择：
>1. Start a service tool
>4. Display/Alter/Dump
>1. DISPLAY/ALTER STORAGE
>2. LICENSED INTERNAL CODE (LIC) DATA
按Pgdn翻页，找到>14. ADVANCED ANALYSIS，回车，进入如下菜单后用1=SELECT选择BATTERYINFO，回车。  
再进入的画面中，OPTIONS输入-LIST即可检查目前RAID卡上电池状态。

F3=EXIT   F4=PROMPT   F12=CANCEL                                            
关于OPTIONS使用帮助：
USAGE: BATTERYINFO <<-INFO> <-FORCE> <-LIST> <-START>>               
                    <<-ALL> <-IOA IOANAMES>>                           
                                                                       
-INFO...: RETRIEVE INFORMATION ABOUT A CACHE BATTERY PACK.            
-FORCE..: FORCE AN ERROR ON A CACHE BATTERY PACK.                     
-LIST...: LIST THE IOAS WHICH CONTAIN CACHE BATTERY PACKS.            
-START..: ENABLE THE IOA CACHE AFTER CONCURRENTLY REPLACING THE CACHE
           BATTERY PACK.                                               
-ALL....: THIS COMMAND IS PERFORMED ON ALL OF THE IOAS THAT CONTAIN   
           CACHE BATTERY PACKS.
-IOA....: THIS COMMAND IS PERFORMED ONLY ON THE SPECIFIED IOAS.   
           YOU MAY SPECIFY ANY NUMBER OF IOAS, SEPARATED BY SPACES.
           FOR EXAMPLE: -IOA DC01 DC02 DC03                        

OS/400 R53M0及以后：

STRSST->1. Start a service tool ->7. Hardware service manage ->9.  WORK WITH RESOURCES CONTAINING CACHE BATTERY PACKS，然后通过5=DISPLAY BATTERY INFORMATION直接检查电池状态。
                                       
二、更换电池前的注意事项：

为了确保更换前存放在CACHE的数据安全写回硬盘，以免可能造成更换电池后丢失数据，在更换前需要强制将电池设成ERROR状态。

1、确保正常关闭AS/400

2、OS/400 R53M0及以后，可以直接通过以下步骤STRSST->1. Start a service tool ->7. Hardware service manage ->9.  WORK WITH RESOURCES CONTAINING CACHE BATTERY PACKS，然后根据RESOURCE NAME、TYPE-MODEL、CARD POSITION等多项参数来确定IOA卡，然后再通过2=FORCE BATTERY PACK INTO ERROR STATE将需要更换的电池升级为ERROR状态。

OS/400 R52M0及以前，可以在上面检查电池步骤的OPTIONS输入-FORCE -IOA DC01（假设更换DC01插槽电池）来强制将电池状态升级为ERROR状态。

3、当电池更换完毕，建议使用在OPTIONS输入：-START -IOA DC01启用新电池。
