本申请涉及一种存储***供电过程中的故障定位方法、装置以及介质。
背景技术
在大数据时代，对存储***的可靠性、智能化控制提出了更高要求，尤其是存储***的供电稳定性，正常情况下存储***由供电电源进行供电，供电电源无法供电时，会切换至备电模块进行供电，因此，保证备电模块能正常运行是十分重要的。备电模块由备份电池单元(Backup Battery Unit，BBU)和BBU控制模块组成。通常情况下，为了对备电模块进行管理，会为备电模块的BBU配备电池管理***(Battery Management System，BMS)，其主要功能是智能化管理及维护备电模块的各个电池单元，防止电池出现过充电和过放电，延长电池的使用寿命，监控电池的状态。图1为一种存储***供电的结构示意图，如图1所示，该结构中：备电模块由BBU10和BBU控制模块11组成，用于给存储***12供电，BBU10、BBU控制模块11以及存储***12之间通过充电链路、放电链路连接，存储***12中还包括***控制器。
如上文提到的存储***在供电环节需要多个设备参与，然而，发明人意识到，目前，存储***使用备电模块供电出现问题时，没有定位问题出现的位置，也就无法针对不同位置的问题采取相应的处理措施。导致存储***的隐患无法及时解决，存储***存在丢失数据的可能。
由此可见，如何定位存储***出现故障的位置，是本领域技术人员亟待解决的问题。
