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.
