FC_REMOTE_PORT_ROLEC(9)                   SCSI mid layer                  FC_REMOTE_PORT_ROLEC(9)



NAME
       fc_remote_port_rolechg - notifies the fc transport that the roles on a remote may have
       changed.

SYNOPSIS
       void fc_remote_port_rolechg(struct fc_rport * rport, u32 roles);

ARGUMENTS
       rport
           The remote port that changed.

       roles
           New roles for this port.

DESCRIPTION
       The 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.

NOTES
       This routine assumes no locks are held on entry.
