Importing a disk group

Importing a disk group enables access by the system to a disk group. To move a

disk group from one system to another, first disable (deport) the disk group on

the original system, and then move the disk between systems and enable (import)

the disk group.

To import a disk group

To ensure that the disks in the deported disk group are online, use the

following command:

# vxdisk -s list

From the vxdiskadm main menu, select Enable access to (import) a disk

group .

At the following prompt, enter the name of the disk group to import (in this

example, newdg):

Select disk group to import [<group>,list,q,?] (default: list)

newdg

When the import finishes, the vxdiskadm utility displays the following success

message:

VxVM INFO V-5-2-374 The import of newdg was successful.

At the following prompt, indicate whether you want to import another disk

group (y) or return to the vxdiskadm main menu (n):

Select another disk group? [y,n,q,?] (default: n)

You can also use the following vxdg command to import a disk group:

# vxdg import diskgroup

Handling cloned disks with duplicated identifiers

A disk may be copied by creating a hardware snapshot (such as an EMC BCV™ or

Hitachi ShadowCopy™) or clone, by using dd or a similar command to replicate

the disk, or by building a new LUN from the space that was previously used by a

deleted LUN. To avoid the duplicate disk ID condition, the default action of VxVM

is to prevent such duplicated disks from being imported.
