Different data from CCW DATA READ as guest or native.
I see this descrepency between TPF native and TPF as a z/VM guest. Has anyone else seen this behavior? Is there any explaination? I have searched high and low, but can't find an answer.

Re: Different data from CCW DATA READ as guest or native.
I'm new to the z/VM arena. I need a good place to start. I'm trying to send a file from z/VM via RSCS to z/OS JES spool. Can someone point me to a good starting place? I do have an RSCS connection between z/VM z/OS. When you display it, it shows active. Thanks Scott
Re: Different data from CCW DATA READ as guest or native.
It should show Connect rather than Active You have started the connection on the VM side, make sure the corresponding CTC on the MVS side is defined to MVS as BCTC if using ESCON and then start the MVS Line Also make sure that the RSCS definition for the JES NODE name matches and the buffer is the same side on both sides.

I think the only difference is the length of path status on a PERFORM SUBSYSTEM FUNCTION: READ SUBSYSTEM DATA operation, the output of which is irrelevant to 2105/2107s anyway. Is this an academic question as a result of late-night studying of responses to CCWs?

Re: Different data from CCW DATA READ as guest or native.
Thanks Alan, It is an issue -when tpf sees an 3990EC – is sees the volume as a control unit that supports TPF record cache. When it sees the volume as 3990E9, TPF marks the control unit as not supporting record cache and several tpf functions are then not available.

CP may need to be sensitive to the TPF Mode state before choosing the CU type.
