Re: TSAF - Supported Links
TSAF's connections are rather old, it was well positioned at the 9370 and 9221 age with their integrated adapters, but nowadays If you can get a CTC connection between the systems, use an IFSC link, that's even simpler than TSAF: CP ACTIVATE ISLINK rdev on both sides, and you're done. BEWARE: SFS resource names (and alike) must be unique. Assure it is before you issue the ACTIVATE command, otherwise you're in trouble. Use Q RESOURCE to find all resource names; alls those that are not LOCAL must be unique. 2008/7/21 Fox Blue [EMAIL PROTECTED]: Dear all, I have two z/VM running on different CPCs. They are joined in a CSE complex. The DASD is shared but spool not since I do not have VM/Pass Through facility. I want to connect now both systems via TSAF as I need to interconnect IUCV and SFS services. After reading the Connectivity Guide (GC24-6118-02) I found out that TSAF would be the right component for doing this. As far as I can understand the setting up of TSAF is quite straight forward. Nevertheless I would need some explanation about the IEEE 802.3 LAN subsystem on rack-mounted processors. This is in my opinion a quite vague description of a feature. What does it mean? Does that mean that the OSA Express2 adapters on my z990s are not supported for TSAF? Aside from CTCs and since I do not have VTAM, Token Ring and BSC stuff, the Ethernet link would be the easiest solution. I would need some confirmation on this. Thank you very much in advance.

Re: TSAF - Supported Links
Hello Kris, Thanks for that information. I will have a look on ISFC. First, I have to get me some CTCs ;-) Best regards, Fox

First, I have to get me some CTCs ;-) For modern configurations, that takes just a foot of fiber to connect two spare chpids. Find an old gray haired person to talk about 3088 where the I/O configuration drawings even X for selected connection and o for broken ... A null modem for those with such heritage. And the neat thing is that our foot of fiber actually is 256 null modem cables. We don't do cross wires, so you configure one chpid as male and the other as female (the political correct term is CTC and CNC).

I guess we need to clean that up. Our first error is letting you conclude that TSAF would be the right component without having alerted you to ISFC. We compounded it by describing hardware that no longer exists. To answer your question, the IBM ES/9221 and its predecessor, the IBM 9370, were rack-mounted machines with integrated network and terminal adapters, as well as having internal dasd. TSAF is still a wonderful alternative for connecting second level systems together or to a first level system since it can use virtual CTCs (ISFC cannot). However, TSAF cannot drive an OSA.
