Fish,
Do you have any special TCPIP settings on the hercules side to go with changing to the OSA from LCS?
I find that OSA seems to be able to FTP at 3 times the speed of the old LCS, but unfortunately if I transfer more than a couple gigabytes, it tends to get lost somehow and times out. As long as I keep the files under 3 GB, it seems to work every time, but when I need to transfer a DASD volume (3390-54 or 3390-27), they tend to be between 5 to 15GB of data so I end up bringing up an older z/os that still supports LCS to do the transfer.
I'm wondering if I have missed something in my definitions. I have offload turned off for the physical windows TCPIP adapter, and in my zos TCPIP parms I also have nochecksumoffload specified, but no other TCPIP config parms relating to the OSA adapter, I just let them all default.
Maybe there is another way to transfer the dasd than using ADRDSSU on both sides. I had heard that some people use CCKDDASD but have not tried that.
