Subject: maintain, distribute multiple copies same-named ZFS files
operating environment here is all z/os 1.13 how am i suppsed to clone and
DISTRIBUTE (with emphasis on *distribute*) zfs files?
CURRENTLY, I have a situation where 6 lpars, 3 production and 3 test, all share
the same master catalog. In that master catalog, the entry for OMVS.ROOT reads
as follows, (i.a.,) : "volser ---- &hfsv1" ; and there are 6 3390s out
there, one for each lpar, each of which has a copy of OMVS.ROOT on it.
Currently, each such omvs.root is an HFS file. Whenever any lpar is ipled, the
value of &hfsv1 is set bmo of an entry in an appropriate IEASYM-- in an
appropriate PARMLIB, and each lpar runs with its own copy of the root, called
.... OMVS.ROOT .
whenever i have a NEW COPY of omvs.root that needs to be distributed, i (1)
drain the 3 test lpars; (2) go to the pack in each test lpar whcih contains
omvs.root and do a "DELETE/NOSCRATCH" for the omvs.root on that pack ; (3)
from a 7th lpar, i copy the new version of omvs.root to the pack in each test
lpar which is supposed to have a copy of omvs.root on it, using a
DISP=(NEW,KEEP). Later on, those 3 "test" lpars are ipled as production lpars.
in this methodology, the entry in the master catalog is never touched, and
nothing in any of the 3 production lpars is ever impacted by whatever i may be
doing in any test lpar. (This g.p. methodology is how i maintain ALL the o/s
image dsn-s) (and, btw, i use this methodology to distribute a couple DOZEN
omvs/unix-system-services dsn-s, not just omvs.root)
the recent emphasis from ibm is, has been, to convert one's HFS files to ZFS.
so, now, given that zfs files are really vsam files, (1) how does one maintain
multiple copies of zfs files off of one master catalog, given that you can't
catalog vsam files using symbolic values in the catalog entry ; (2) next,
assuming that there is some method -- unknown to me at the present moment -- to
maintain multiple copes of identically-named vsam files off of one catalog ,
how do i go about distributing new copies of zfs files, using my methodology
that I described above? First of all, if I follow the above-described
scenario, the first time i try to delete a zfs file (a vsam file, now) , isn't
that going to also erase the catalog entry for it (and wreak some havoc for
the remaining 5 lpars, which are also still using the catalog) ? Second of
all, there is/are the VVDS entries, something I need not bother myself about in
my current methodology (b/c in that, no vsam files are involved) -- how do i
keep them sync-ed up? (3) i tried to consult several books about this , i.a.,
"z/os distributed file service file system implementation" , "distributed file
sevice zSeries file system Administration" and " volume 9, ABCs of system
programming" and "z/FS reorganization tool" , and i just can't get this to work
, at least in the context of the methodology i currently use to distribute
omvs/unix-system-services dsn-s. Maybe i need to totally change my
methodology? EXACTLY how are other people doing this kind of thing?
