Remove a disk for replacement
Menu: VolumeManager/Disk/RemoveForReplace
Use this menu operation to remove a physical disk from a disk
group, while retaining the disk name. This changes the state
for the disk name to a "removed" disk. If there are any
initialized disks that are not part of a disk group, you will be
given the option of using one of these disks as a replacement.
Enter disk name [,list,q,?] list
Disk group: rootdg

dm rootmirr c0t1d0s2 sliced 2888 71124291 -
Enter disk name [,list,q,?] rootdisk
The following volumes will lose mirrors as a result of this
operation:
rootvol swapvol
No data on these volumes will be lost.
The requested operation is to remove disk rootdisk from disk group
rootdg. The disk name will be kept, along with any volumes using
the disk, allowing replacement of the disk.
Select "Replace a failed or removed disk" from the main menu
when you wish to replace the disk.
Continue with operation? [y,n,q,?] (default: y) y
Removal of disk rootdisk completed successfully.
Remove another disk? [y,n,q,?] (default: n) n

4.在此需要修改一下dump设备路径，将dump设备路径指向mirror盘，不然从设备树中删除根盘的时候会有问题：
root@sun # cfgadm -c unconfigure c0::dsk/c0t0d0
cfgadm: 部分系统忙，重试: 脱机失败：

5.带好防静电手套，更换根盘；
6.重配根盘；

Use this menu operation to specify a replacement disk for a disk
that you removed with the "Remove a disk for replacement" menu
operation, or that failed during use. You will be prompted for
a disk name to replace and a disk device to use as a replacement.
You can choose an uninitialized disk, in which case the disk will
be initialized, or you can choose a disk that you have already
initialized using the Add or initialize a disk menu operation.

如果卷状态如上说明换盘成功！
有时实际和我的环境还是有很大出入的，可能用vxdiskadm选4选5换不了，或是换了以后同步有问题等等，欢迎大家拍砖。。。。。
