Hi,Martin Thanks for your reply. The command "multipathd list paths format %N %R %n %r" or "lsscsi -t" shows all the paths. The new command "multipath -k" removes the path of information with the same host wwn and target wwn, only display the different physical path which is between a server and the storage device in storage networking. We think this command will make it easier to observe physical path information. Best regards.
