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, use the following procedure:

1. Use the following command to ensure that the disks in the deported disk group are online:
     # vxdisk -s list
2. Select menu item 7 (Enable access to (import) a disk group) from the vxdiskadm main menu.
3. At the following prompt, enter the name of the disk group to import (in this example, newdg):
     Enable access to (import) a disk group 
     Menu: VolumeManager/Disk/EnableDiskGroup 
   
     Use this operation to enable access to a
     disk group. This can be used as the final part of moving a disk
     group from one system to another. The first part of moving a disk
     group is to use the "Remove access to (deport) a disk group"
     operation on the original host. 
   
     A disk group can be imported from another host that failed
      without first deporting the disk group. Be sure that all disks
      in the disk group are moved between hosts.
   
     If two hosts share a SCSI bus, be very careful to ensure that
      the other host really has failed or has deported the disk group.
      If two active hosts import a disk group at the same time, the
      disk group will be corrupted and will become unusable. 
     Select disk group to import [<group>,list,q,?] (default: list)
      newdg 

   Once the import is complete, the vxdiskadm utility displays the following success message:

   
     VxVM INFO V-5-2-374 The import of newdg was successful. 
4. 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) 

Alternatively, you can use the vxdg command to import a disk group:
