Or perhaps whatever has/will replace it? The reason that I ask is that it seems that while DFSMSdfp clings tenaciously to the 3390 DASD architecture, it is also using this interface (with 4K physical blocks) for all new I/O. IIRC, it was first just a part of VSAM. I am not sure, but I'd bet that PDS/E and HFS use it as well. Is this the "master plan" so that all access methods will eventually use this one interface? I could go with that if it meant that eventually non-3390 DASD architectures (such as SCSI/SAN) were supported.
Just Friday musings. Brought on by my dislike of zFS being based on LDS data sets. Because what I recently needed was a really huge (10 x 3390-3) UNIX filesystem. Which meant a new storage class & storage group for segregation from other data. In the past (non-VSAM, non-HFS), I could just grab some "free" volumes and create a multi-volume dataset on them. Not any more. What a bother. -- John ---------------------------------------------------------------------- For IBM-MAIN subscribe / signoff / archive access instructions, send email to lists...@bama.ua.edu with the message: GET IBM-MAIN INFO Search the archives at http://bama.ua.edu/archives/ibm-main.html
