You can create a single snapmirror.conf file for your site and copy it to all the storage systems that use SnapMirror. The snapmirror.conf file can contain entries pertaining to other storage systems.
For example, the /etc/snapmirror.conf
file on systemB can contain an entry for copying a volume from system C to system D. When systemB reads the /etc/snapmirror.conf
file, it ignores the entries for other storage systems
Note: Each time the file is read, a warning message is displayed on the storage system console for each line that is ignored.
