A5000阵列更换硬盘步骤

由于主机上的xyz磁盘组的一个硬盘损坏需要对这个硬盘进行更换，更换的步骤如下：
1、        通过vxdisk –g xyz list显示的信息确定磁盘已经损坏。（以及从图形界面上看到的相关信息）
bash-2.03# vxdisk -g xyz list
DEVICE       TYPE      DISK         GROUP        STATUS
c2t66d0s2    sliced    c2t66d0s2    xyz         online
c2t67d0s2    sliced    c2t67d0s2    xyz         online
c2t69d0s2    sliced    c2t69d0s2    xyz        online
c2t82d0s2    sliced    c2t82d0s2    xyz         online
c2t83d0s2    sliced    c2t83d0s2    xyz         online failing
c2t85d0s2    sliced    xyz01       xyz         online spare
由于损坏的磁盘为：c2t83d0s2根据磁盘的t83确定磁盘为A5000后部的第4块磁（slot （因为A5000是按照box ID 2的规则进行编码的）。（现在A5000的状况图如下：）

2、移出坏盘并且替换新盘（损坏的磁盘是建立在一个RAID5卷上的）
    1) 运行vxdiskadm，选择4：Remove a disk for replacement   使用list查看逻辑盘域物理盘的对应情况，然后选择故障盘c2t83d0s2，将该盘根据系统提示逐步移去。
2) 运行luxadm remove_device Aa,r3 将c0t83d0从系统中移出（我在运行这个步骤的时候，由于开始没有成功所以使用了-F参数，对后面没有影响）。具体过程如下：
   # luxadm remove_device  –F  Aa,r3
当提示回车继续时，从阵列上拆下硬盘。然后按回车键继续，直到硬盘成功从操作系统中移出。
3）将新硬盘插入阵列中，然后reboot，并利用ctrl+d进入系统。
4）系统启动完成后，运行
   # luxadm insert_device Aa,r3
   #vxdctl enable
将新盘加入到操作系统中。
5）运行vxdiskadm，选择5：Replace a failed or removed disk ，选择c2t83d0s2，在选择c0t83d0。
6）硬盘替换成功后，系统会根据你的log进行恢复你的RAID5卷的。可以使用vxtask list查看你同步运行的情况。

我在更换磁盘的时候遇到了以下的问题，在我执行vxdiskadm替换的时候报了lisence的错误，看了一下lisence以后感觉有问题，找了一个临时的lisence输入进去。在替换以后成功。
