In the first example, cloned disks (ShadowImage™ devices) from an Hitachi TagmaStore array will be imported. The primary (non-cloned) disks, mydg01, mydg02 and mydg03, are already imported, and the cloned disks are not tagged.

# vxdisk -o alldgs list

DEVICE             TYPE         DISK    GROUP   STATUS
TagmaStore-USP0_3  auto:cdsdisk -       (mydg)  online udid_mismatch
TagmaStore-USP0_23 auto:cdsdisk mydg02   mydg   online
TagmaStore-USP0_25 auto:cdsdisk mydg03   mydg   online
TagmaStore-USP0_30 auto:cdsdisk -       (mydg)  online udid_mismatch
TagmaStore-USP0_31 auto:cdsdisk -       (mydg)  online udid_mismatch
TagmaStore-USP0_32 auto:cdsdisk mydg01   mydg   online

To import the cloned disks, they must be assigned a new disk group name, and their UDIDs must be updated:

# vxdg -n snapdg -o useclonedev=on -o updateid import mydg
# vxdisk -o alldgs list

DEVICE             TYPE         DISK    GROUP   STATUS
TagmaStore-USP0_3  auto:cdsdisk mydg03  snapdg   online clone_disk
TagmaStore-USP0_23 auto:cdsdisk mydg02  mydg    online
TagmaStore-USP0_25 auto:cdsdisk mydg03  mydg    online
TagmaStore-USP0_30 auto:cdsdisk mydg02  snapdg   online clone_disk
TagmaStore-USP0_31 auto:cdsdisk mydg01  snapdg   online clone_disk
TagmaStore-USP0_32 auto:cdsdisk mydg01  mydg    online

Note that the state of the imported cloned disks has changed from online udid_mismatch to online clone_disk.

In the next example, none of the disks (neither cloned nor non-cloned) have been imported:

# vxdisk -o alldgs list

DEVICE             TYPE         DISK    GROUP   STATUS
TagmaStore-USP0_3  auto:cdsdisk -       (mydg)  online udid_mismatch
TagmaStore-USP0_23 auto:cdsdisk -       (mydg)  online
TagmaStore-USP0_25 auto:cdsdisk -       (mydg)  online
TagmaStore-USP0_30 auto:cdsdisk -       (mydg)  online udid_mismatch
TagmaStore-USP0_31 auto:cdsdisk -       (mydg)  online udid_mismatch
TagmaStore-USP0_32 auto:cdsdisk -       (mydg)  online

To import only the cloned disks into the mydg disk group:

# vxdg -o useclonedev=on -o updateid import mydg
# vxdisk -o alldgs list

DEVICE             TYPE         DISK    GROUP   STATUS
TagmaStore-USP0_3  auto:cdsdisk mydg03  mydg    online clone_disk
TagmaStore-USP0_23 auto:cdsdisk -      (mydg)   online
TagmaStore-USP0_25 auto:cdsdisk -      (mydg)   online
TagmaStore-USP0_30 auto:cdsdisk mydg02  mydg    online clone_disk
TagmaStore-USP0_31 auto:cdsdisk mydg01  mydg    online clone_disk
TagmaStore-USP0_32 auto:cdsdisk -      (mydg)   online

In the next example, a cloned disk (BCV device) from an EMC Symmetrix DMX array is to be imported. Before the cloned disk, EMC0_27, has been split off from the disk group, the vxdisk list command shows that it is in the error udid_mismatch state:

# vxdisk -o alldgs list
DEVICE             TYPE         DISK    GROUP  STATUS
EMC0_1             auto:cdsdisk EMC0_1  mydg   online
EMC0_27            auto         -       -      error udid_mismatch

The symmir command is used to split off the BCV device:

# /usr/symcli/bin/symmir -g mydg split DEV001

After updating VxVM's information about the disk by running the vxdisk scandisks command, the cloned disk is in the online udid_mismatch state:

# vxdisk -o alldgs list
DEVICE             TYPE         DISK    GROUP  STATUS
EMC0_1             auto:cdsdisk EMC0_1  mydg   online
EMC0_27            auto:cdsdisk -       -      online udid_mismatch

The following command imports the cloned disk into the new disk group newdg, and updates the disk's UDID:

# vxdg -n bcvdg -o useclonedev=on -o updateid import mydg

The state of the cloned disk is now shown as online clone_disk:

# vxdisk -o alldgs list
DEVICE             TYPE         DISK    GROUP  STATUS
EMC0_1             auto:cdsdisk EMC0_1  mydg   online
EMC0_27            auto:cdsdisk EMC0_1  bvcdg  online clone_disk
