1) # multipath -l : Command to view the configured multipath devices.
2) # cd /proc/scsi : Location of the HBA file which contains the WWN Number. In Linux, the HBA files are stored as 0,1.... The same numbering notation reflects in the "multipath" output.
3) /etc/multipath.conf : Configuration file for multipath.
4) # multipathd -k : Command which opens the interactive console with the ">" prompt.
>show paths : Command shows all the configured multipaths.
>show maps : Command shows all mapping of LUN.
