6027-470 Disk name may still belong to file system filesystem. Created on IPandTime.
Explanation
The disk being added by the mmcrfs, mmadddisk,
or mmrpldisk command appears to still belong
to some file system.
User response
Verify that the disks you are adding do not belong
to an active file system, and use the -v no option
to bypass this check. Use this option only if you are sure that no
other file system has this disk configured because you may cause data
corruption in both file systems if this is not the case.
