SAS_PORT_ADD_PHY(9)						  SCSI mid layer					       SAS_PORT_ADD_PHY(9)

NAME
       sas_port_add_phy - add another phy to a port to form a wide port

SYNOPSIS
       void sas_port_add_phy(struct sas_port * port, struct sas_phy * phy);

ARGUMENTS
       port
	   port to add the phy to

       phy
	   phy to add

DESCRIPTION
       When a port is initially created, it is empty (has no phys). All ports must have at least one phy to operated, and all wide ports must have
       at least two. The current code makes no difference between ports and wide ports, but the only object that can be connected to a remote
       device is a port, so ports must be formed on all devices with phys if they're connected to anything.
