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.
