That is incorrect. I routine share channels across LPARs. The purpose of the switch is to connect multiple physical CECs to a single device. -----Original Message----- From: IBM Mainframe Discussion List <IBM-MAIN@LISTSERV.UA.EDU> On Behalf Of R.S.

You cannot share chpid without the switch. It is point to point topology, not daisy chains like in Bus&Tag. Note, second hand switch with 8Gbps speed can be purchased just for peanuts. Regarding CTC, I think it is well documented. It was documented when I read about it years ago when I moved from ESCON to FICON. -- Radoslaw Skorupka Lodz, Poland ====================================================================== Jeśli nie jesteś adresatem tej wiadomości: - powiadom nas o tym w mailu zwrotnym (dziękujemy!), - usuń trwale tę wiadomość (i wszystkie kopie, które wydrukowałeś lub zapisałeś na dysku).
