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 ?
