I'm having issues with that link also. *To enable user-friendly names or to specify aliases:* -
*In a terminal console, log in as the root user.* - *Open the /etc/multipath.conf file in a text editor.* *(Optional) Modify the location of the /var/lib/multipath/bindings file. * *The alternate path must be available on the system root device where multipath can find it. * - *Move the /var/lib/multipath/bindings file to /etc/multipath/bindings.* *Set the bindings_file option in the defaults section of /etc/multipath.conf to this new location. For example:* On my system I don't have any of those files. /etc/multipath.conf /var/lib/multipath <-- that subdirectory does exist in /var/lib On Thu, Aug 25, 2016 at 12:33 PM, Mark Pace <[email protected]> wrote: > Thank you for the comments and the link.
