Don, Actually I would like the DS1LSTAR and the DS1DSORG to be set. The DS1LSTAR should be set to the "end" TTR of the partition. The DS1DSORG should be set to 0x2000. This should not have any effect on the Linux side of the house. However, this will set the DSORG to DA and the dataset to "100% full" on the OS/390 side of the house. This would allow a simple IEBGENER to copy the entire partition.
Now, you are probably wondering "what is this fool doing, wanting access to the Linux partition from OS/390 in this manner?" It has to do with my desire to transfer entire partitions between my z800 running Linux/390 "natively" and my Linux/Intel running Hercules which runs Linux/390 in the Hercules emulator. I was thinking of using the OS/390 ftp server to do this. The change mentioned would allow this. However, I have since found a "better" way by using "dd" and "ssh" to just copy the /dev/.... block device directly to Linux/Intel. I got "hung up" on how to use ftp to do this transfer. Another person showed me how to do the "dd | ssh" combination to get what I want. So, I guess it is no longer needed by me. Unless somebody is crazy enough to want to create an OS/390 program which could directly read / write a Linux filesystem. Not that I'm advocating doing this. But it is an interesting thought to me. -- John McKown Senior Systems Programmer UICI Insurance Center Applications & Solutions Team +1.817.255.3225 This message (including any attachments) contains confidential information intended for a specific individual and purpose, and its' content is protected by law.
