vxvm rootdisk 封装和解除封装

云知道

环境：ultra1 2块硬盘
已经配置rootdg内包含一个slice c0t0d0s5
系统盘上的slice 5 6 7 各有100m空间 其余空间都给了/ 和swap
试验内容为将根盘封装，然后景象 。试验景象盘能够引导系统，最后解除景象和封装 。
Rootdisk encapsulate
1.add new disk slice at rootdg
root@sunlab # vxdctl add disk c0t1d0s5 type=simple
vxvm:vxdctl: WARNING: Device c0t1d0s5: Not currently in the configuration
root@sunlab # vxdisk -f init c0t1d0s5 type=simple
root@sunlab # vxdg adddisk c0t1d0s5
root@sunlab # vxdctl enable
vxdisk list

2.remove rootdisk slice at rootdg
root@sunlab # vxdctl rm disk c0t0d0s5
root@sunlab # vxdg -g rootdg rmdisk c0t0d0s5
root@sunlab # vxdisk rm c0t0d0s5
