Source: NCP Engine
Explanation: The NCP engine could not rename across volumes because the source volume and destination volume are different.
Action: Although the RENAME command can move a file between directories on the same volume, using RENAME to move a file between volumes is not allowed.
If you have sufficient privileges on both NSS volumes, you can map a drive to each volume, and then use the Novell Client's copy option to copy the file or folder between the two volumes along with the trustee and file access metadata.
