1.该solaris 系统（该系统做了raid 1 ）中出现错误（红色字体标注），是要换硬盘么？若换硬盘，能不能求教步骤或者方法。
2.为什么在d36 和 d37 中使用的是每个硬盘的0分区（每个硬盘大小是73.4G，iostat -En命令中显示），而d36和都d37的大小是三个硬盘大小之和？
谢谢 ，新手很希望得到朋友们的指导。刚接触solaris系统。
镜像需要维护了，还不能确定就是硬盘的问题，但是c0t11d0 坏的可能性很大，建议多搜集一些信息进行判断。。 先重启一下，或许重启后就硬盘恢复正常了，不行的话就要换盘了
呵呵谢谢 8894106 qianxia0_ 关注此贴 和给出的建议。这个问题已经解决了。 不嫌麻烦，说下解决方法呗:mrgreen::mrgreen: 更换c0t11d0 其实就只能是换盘了
