Hello @Dsinghp2002,

Please ensure that the copy CPG is defined for the parent volume.

Can you also share the complete command or GUI steps you tried?

Hello @Dsinghp2002,

These volumes don't have copy CPGs assigned. Please assign a copy CPG for the volume and retry.

4. Go to the Actions menu and click Edit.
5. Under Protection and Additional Settings section, click Volume.

[AnilKT · Accepted solution]

Hello @AnilKT and @Dsinghp2002,

To add a correction, The command is setvv -snp_cpg <CopyCPGname> <VVname>

(There is a space between 'snp_cpg' and the copy CPG name.)

As this issue is not caused by same reason, thus there won’t be one solution to get rid of this error. This section provides A couple of easy solutions and you can try them one after another.

Solution 1: Format target partition into NTFS or exFAT

If the file you try to copy is no less than 4GB, you can compress it with WinRAR, thus you can get a smaller file. This solution does not work on all case, thus you need to change file system format for target disk.

-Open Windows Explorer by double-clicking Computer or This PC.
-Backup files for target partition. Formatting erases data, thus you need to backup data before formatting it. It’s easy to backup files, as you can simply copy file from this partition to another.
-Right-click this partition and select “Format”. Then you can select file system as NTFS or exFAT and click “OK”. Note: if your system can’t set needed file system, you can use PartitionGuru to do the formatting job.

This may help you,
