１在换电池之前可以用命令查看电池已用多少天
>.id read uxpcux (x 为数字１or２)
２在线更换Ｔ３电池还有一个要注意！
　当系统Ｉ／Ｏ很忙的情况下不能在线更换电池，因为在更换电池后，在充电的１０个小时内，Ｔ３会关闭ＣＡＣＨＥ，充完后会自动起来，但是一般会降低Ｔ３的性能15%左右，在特别忙的时候，会使主机切换或挂起应用。有的数据库不能用，有的会使卷的PLEX DETACHED IOFAIL。
3#TOP 查看 I/O，CPU，MEMORY的使用情况。
4要是发生PLEX DETACHED IOFAIL。要用#vxrecover -b VOL-NAME
来修复，要是数据很大的话，可能要10个小时啊！
