MegaCli:如何使用命令行监控RAID卡状态

2024-06-04 06:37| 来源: 网络整理| 查看: 265

简介

MegaCli是一款管理维护硬件RAID软件,可以通过它来了解当前raid卡的所有信息,包括 raid卡的型号,raid的阵列类型,raid 上各磁盘状态,等等。通常,我们对硬盘当前的状态不太好确定,一般通过机房人员巡检来完成,有没有通过软件的方式来检查确定这个问题呢。MegaCli就可以做到,一般通过 MegaCli 的Media Error Count: 0 Other Error Count: 0 这两个数值来确定阵列中磁盘是否有问题;Medai Error Count 表示磁盘可能错误,可能是磁盘有坏道,这个值不为0值得注意,数值越大,危险系数越高,Other Error Count 表示磁盘可能存在松动,可能需要重新再插入。MegaCli 可以对阵列中所有的磁盘进行检测,我们可以通过脚本的方式来检测相关参数,从而通知管理人员。
