int sas_discover_root_expander

dev

Definition at line 1640 of file sas_expander.c.

int sas_ex_phy_discover	(	struct domain_device *	dev,

int sas_ex_revalidate_domain

(

struct domain_device *

port_dev

)

sas_revalidate_domain – revalidate the domain : port to the domain of interest

NOTE: this process must quit (return) as soon as any connection errors are encountered. Connection recovery is done elsewhere. Discover process only interrogates devices in order to discover the domain.
