Hello listers, We are upgrading the zVM 5.4 to RSU 0903. I am looking at enrolling this upgrade from the install system to our production VM's. Our install VM contains the full VMSES environment, our production VM's only contain the
productsdisks that are required for running VM. For instance, only MAINT 193 is available in production, the MAINT 493 is only in the install VM. Basically we would like to transfer only those files that have been chang ed by the RSU and/or PTF's. I compare the LISTFILE (ISO for all minidisks fr om the old and new install VM to find files that have been changed. Either a change in date/time, records or blocksize will be noticed, as well as new files. Next I only select the minidisks that are in the production VM's a nd the files on that minidisks that have been changed. Obviously, some disks can't be tranferred this way, the MAINT 190 is transferred using DDR so that we transfer the entire disk instead of only the S-disk. Now I do see files that have been changed but do not have the filedate se t to the date of applying the RSU. That makes me wonder, could there be a f ile that is changed but is not found this way? For instance, a file where a b yte has been changed but that is not reflected in a change in filesizes or timestamp? Also, would copying files have impact on other functions? When the 190 or 19E is changed CMS has to be rebuild. Could the same be true for segments such as HELPSEG or CMSFILES (to name a few)? Segments are copied/transfer red using the DCSSBKUP but are these still valid when individual CMS members are copied too? TIA, Berry.
