One of my managers told me that since you could make both ECKD (FICON) and SCSI (FCP) connections to the same IBM Storage subsystem, z/Linux should be able to read z/OS data off the z/OS volumes, without any special formatting by z/OS. I asked IBM and they said it couldn't be done - z/Linux cannot read z/OS data and vice-versa.
Is this correct? If so, what would it take to make z/Linux able to read z/OS data directly? New drivers? A new file system? How hard would this be to write? I am aware that you can access z/OS data from z/Linux (or any Linux) over the network via one of: * NFS mount * Samba mount * Co:Z Co-Processing Toolkit That's not what I am looking for here. Our objective is to lower z/OS MIPS by moving workload to z/Linux. A network "mount" would certainly cost some z/OS MIPS. Moving workload to z/Linux without moving data would save money because IFLs cost less than standard engines and the software cost of Linux is lower than that of z/OS.
