*1 If an error occurs when the volume is being unmounted

[Solaris versions/Linux versions/HP-UX versions/AIX versions]

Check that the target volume can be unmounted.

To suppress data access to guarantee data integrity, preprocessing unmounts the copy source volume. For this reason, if the target volume is being used when copy is run, an error occurs because the volume cannot be unmounted. Note the following points when the volume cannot be unmounted:

You may be able to investigate if a volume is in use by using the following commands. For details on these commands, see the OS manuals.

[Solaris] mount, fuser, pfiles, share

[Linux/HP-UX/AIX] mount, fuser
