If this helps, here is how I have mine mounted: >From our RHEL server named ldxzvm03 in /etc/fstab: hiper-cpur:/hfs/u/abcdef,binary /sftp/abcdef/center3 nfs rw,hard,intr 0 0
hiper-cpur is the Hipersocket IP of a z/OS LPAR. On the z/OS side, we have the following defined in the NFS export file: /hfs/u/abcdef -access=hiper-ldxzvm03 hiper-ldxzvm03 being the Hipersocket IP of our Linux guest. Any translation would be specified in the mount commands (man mount on the Linux side) or in the servers NFS attributes file. In our case we are pushing things across in binary mode. Some of the z/OS side NFS server attributes you might want to look at are: # translate related text/binary CR, CRLF, LF, LFCR, or NOEOL. blankstrip xlat(member) cln_ccsid(819) srv_ccsid(1047) # for files created via NFS recfm(vb), blksize(0), lrecl(8196) dsorg(ps) space(100,10), blks norlse dir(27) So the answer is "it depends" on if/how you mount the client and configure the server as to whether data is automatically translated. We have some MVS data sets mounted out to AIX that we translate automatically. One thing we ran into there was when we converted some of our AIX files to Unicode. NFS can't tranlsate a multi-byte character set down to a single-byte character set, so beware of the code pages. Or, make the NFS mount binary and translate it once you get to the other side with something outside of NFS. We do both ways. z/OS NFS manual: http://publibz.boulder.ibm.com/cgi-bin/bookmgr_OS390/BOOKS/CPN1CO60/CONTENTS?SHELF=CPN1BS60&DT=20080710133848 __________________________________ Tom Stewart Infrastructure Analyst John Deere - z/OS Support Services em: [EMAIL PROTECTED] __________________________________ -----Original Message----- From: Linux on 390 Port [mailto:[EMAIL PROTECTED] On Behalf Of Patrick Leigh Sent: Wednesday, September 24, 2008 12:59 PM To: LINUX-390@VM.MARIST.EDU Subject: NFS - z/OS and Linux TNG here, so please bear with me. I am in need of additional information regarding an NFS mount between z/OS and Linux (RHEL). I understand the how-to. It is more of the underlying process that I am curious about. Particularly, if once mounted (zOS being server, and Linux being client) and writing/copying file directly to mounted directory, is there translation going on (I assume yes). and also, are the file attributes (record length, blocksize, etc) required/preserved when going to/from? Basically, what I am trying to do is share data between z/OS and Linux. I have found the other thread "zLinux access to z/OS DASD<http://www.mail-archive.com/linux-390@vm.marist.edu/msg47939.html>" and appears that final recommendation is to go with NFS mount, but need to know the above information. I apologize if I've mixed any concepts. Thanks for any information.
