The filers involved in a volume copy operation must meet several requirements for
data to be copied successfully. The following list is a brief description of these require-
ments. The rest of this section provides more detailed information about verifying
whether the source and destination volumes meet these requirements.
The source volume must be on-line and the destination volume must exist and be
off-line.
The destination volume must not be the root volume because the destination vol-
ume must be off-line when the filer executes the vol copy command, and a
root volume must always be on-line.
The capacity of the destination volume must be greater than or equal to the
capacity of the source volume.
The destination volume must not contain data that you want to preserve.
The source and destination filers must have a trusting relationship with each
other.
The localhost interface must be specified as a trusted host if data is copied on
the same filer.

The destination volume must exist before you enter the vol copy start com-
mand to start copying a volume. If the volume does not exist, the command does not
create the volume and the command returns an error. See Creating Volumes in
Chapter 3 for information about how to create a volume.
After you verify that the destination volume exists, check the status of the source vol-
ume and the destination volume.

The source volume must be on-line and the destination volume must be off-line. To
verify whether a volume is on-line or off-line, use the following command syntax:
vol status
volume_name
