Error Message

To resolve the import failure and the "No clone disks for import" error, follow these steps:

1. Manually update the UDID of the clone disks:

   • Use the command vxdisk updateudid diskname to update the UDID of each clone disk.
   • If the update fails, try using the -Cf option with the command, e.g., vxdisk -Cf updateudid diskname.

2. Remove the clone disks that are not part of the disk group on the source system:

   • Run the command vxdisk rm diskname for each clone disk that is not part of the disk group.
   • Ensure that only the necessary clone disks remain.

3. Attempt to import the disk group on the target system:

   • Use the command vxdg -Cft import dgname to import the disk group.
   • If the import is successful, verify the status of the volumes using the vxprint command.

4. Resolve any disabled active volumes:

   • If the volumes are in a disabled active state, try starting them using the vxvol start volname command.
   • If an error related to DCO (Disk Change Object) is encountered, use the vxassist command to remove DCO on the affected volume, e.g., vxassist -g dgname -r dco off volname.

5. Verify the successful migration of storage:

   • Check the system's functionality and ensure that the storage migration from Hitachi to Pure using VXVM mirroring has been completed successfully.
