Hi,

>> How could it connect LPARs if one end goes to DASD or TAPE?

I think it is possible only with a Ficon Director (Switch). The switch 
"redistribute" the connections, and allow a mixed of devices (CTC, TAPEs 
and DASDs) on the unique Ficon channel. 
And you can use a single channel (not a pair) to do CTCs between several 
LPARs on the same CEC. The signal goes to switch and returns by the same 
channel, "two-way"...

Really? Wouldn't a FICON channel that is being used for CTC between LPARs 
need to have *both* ends attached to FICON cards in the computer, the way 
an ESCON
CTC is built? How could it connect LPARs if one end goes to DASD or TAPE?

I do not yet have FICON (till next month....) but I am interested in 
learning!

Thanks,
Shimon

Hi Martha,

it is not necessary to reserve some FICON Links for only CTC. You can 
share them for DASD, TAPE and FICON-CTC.

Kind regards,

Alexander

Betreff: ISFC connection between LPARs

Its been a long while since I had to create an ISFC connection. We are 
finally
getting a z10 and I need to create a link between the two main LPARs.  I
don't have ESCON adapters in this box and I'd really hate to use up a
couple of FICON just for a CTC connection between the 2 LPARs.

Is there any other way to do this on a z10?

Martha
