NAMEfc_remote_port_rolechg − notifies the fc transport that the roles on a remote may have changed​.

---

SYNOPSISvoid fc_remote_port_rolechg(struct fc_rport * rport, u32 roles);

---

ARGUMENTSrport The remote port that changed​. roles New roles for this port​.

---

DESCRIPTIONThe LLDD calls this routine to notify the transport that the roles on a remote port may have changed​. The largest effect of this is if a port now becomes a FCP Target, it must be allocated a scsi target id​. If the port is no longer a FCP target, any scsi target id value assigned to it will persist in case the role changes back to include FCP Target​. No changes in the scsi midlayer will be invoked if the role changes (in the expectation that the role will be resumed​. If it doesn´t normal error processing will take place)​. Should not be called from interrupt context​.

---

NOTESThis routine assumes no locks are held on entry​.
