As usual, when I ask question I find answer shortly after :) This is from the same redbook
The FICON channel at each end of the FICON CTC connection, supporting the FCTC control units, can also communicate with other FICON native control units, such as disk and tape. So chpid is type FC and then there are CU of FCTC and 3990. I like to answer myself :) Marian On 7/20/05, Marian Gasparovic <[EMAIL PROTECTED]> wrote: > Hi all, > I would like to ask if it is possible to use one FICON cable for both > disk access and CTC.
