NAME

6       sas_port_add_phy - add another phy to a port to form a wide port
7

SYNOPSIS

9       void sas_port_add_phy(struct sas_port * port, struct sas_phy * phy);
10

ARGUMENTS

12       port
13           port to add the phy to
14
15       phy
16           phy to add
17

DESCRIPTION

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