.SH "DESCRIPTION"
.PP
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\*(Aqt normal error processing will take place)\&.
.PP
Should not be called from interrupt context\&.
.SH "NOTES"
.PP
This routine assumes no locks are held on entry\&.
