1.查看电池信息
命令：smitty pxdam
选择“ Diagnostics and Recovery Options”
选择“Controller Rechargeable Battery Maintenance”
回车，可以看到电池信息
电池信息各参数含义如下：
battery state：显示电池当前具体状态，有以下几个可能的值
No battery warning/error：No warning or error condition currently exist 这种是电池的正常状态
Warning condition：A warning condition currently exists and an error has been logged 出现了一个警告并被记录在日志中
Error condition：An error condition currently exists and an error has been logged 电池已经出错
Unknow：Information is not available to determine whether a warning or error condition currently exists 无法判断
Power-on time（days）：电池持续使用的天数
Adjusted power-on time（time）：
Indicates the adjusted (prorated) power-on time, in units of days ,of the rechargeable Cache Battery Pack
Note：Some rechargeable Cache Battery Packs are negatively affected by higher temperatures and thus are prorated based on the amount of time that they spend at various ambient temperatures
Estimated（估算的） time to warning（days）:
Estimated time, in units of days, until a message is issued indicating that the replacement fo the rechargeable Cache Bettery Pack should be scheduled
Estimated time to error（days）：当值为0时，此时Cache被自动禁用，必须更换电池
Estimated time , in units of days ,until an error is reported indicating that the rechargeable Cache Bettery Pack must be replaced
Concurrently maintainable battery pack：该电池是否可以在线更换
Indicates that the rechargeable Cache Battery Pack can by replaced while the adapter continues to operate
Battery pack can be safely replaced：当值为YES时，该电池可以安全地更换，不会造成Cache数据丢失
Indicates that the adapter's write cache has been disabled and the rechargeable Cache Battery Pack can be safely replaced
2.强制将电池置为Error状态，使写Cache禁用，清空Cache内缓存的数据
命令：smittty pxdam
选择“Force Controller Rechargeable Battery Error”
最好再检查一次，电池信息中“Battery pack can be safely replaced”一项为YES
3.更换电池
注意：必须将旧电池拆下来至少15秒后，再安装新电池，否则PCI-X SCSI RAID卡将不能正常识别电池已更换。
注意：必须确保电池已处于Error状态，才能更换电池，以免Cache中缓存的数据丢失。
根据PCI-X SCSI RAID卡的不同类型，选择Concurrent方式或Non-Concurrent方式更换：
Non-Concurrent方式更换
更换电池必须将卡从机器中拔出
A Battery Pack Casing
B Cache Directory Card
Concurrent方式更换：
更换电池可以在线进行，只需单独将电池拔出，不需要把卡从机器中拔出
4.重新激活写Cache
