vxvm rootdisk 的封装和解除封装

  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     DEVICE TYPE DISK GROUP STATUS   c0t0d0s2 sliced - - error   c0t0d0s5 simple c0t0d0s5 rootdg online   c0t1d0s2 sliced - - error   c0t1d0s5 simple c0t1d0s5 rootdg online   2.remove rootdisk slice at rootdg   root@sunlab # vxdctl rm disk c0t0d0s5   root@sunlab # vxdg -g rootdg rmdisk c0t0d0s5   root@sunlab # vxdisk rm c0t0d0s5   root@sunlab # vxdisk list   DEVICE TYPE DISK GROUP STATUS   c0t0d0s2 sliced - - error   c0t1d0s2 sliced - - error   c0t1d0s5 simple c0t1d0s5 rootdg online   root@sunlab # vxdiskadm   Menu: VolumeManager/Disk   1 Add or initialize one or more disks   2 Encapsulate one or more disks   3 Remove a disk   4 Remove a disk for replacement   5 Replace a failed or removed disk   6 Mirror volumes on a disk   7 Move volumes from a disk   8 Enable Access to (import) a disk group   9 Remove access to (deport) a disk group   10 Enable (online) a disk device   11 Disable (offline) a disk device   12 Mark a disk as a spare for a disk group   13 Turn off the spare flag on a disk   14 Unrelocate subdisks back to a disk   15 Exclude a disk from hot-relocation use   16 Make a disk available for hot-relocation use   17 Prevent multipathing/Suppress devices from VxVM's view   18 Allow multipathing/Unsuppress devices from VxVM's view   19 List currently suppressed/non-multipathed devices   20 Change the disk naming scheme   Hit RETURN to continue.   21 Get the newly connected/zoned disks in VxVM view   list List disk information   ?
