Re: Backout PTF(s) applied
Hi Steve, The VMSES/E way to remove a PTF is with VMFREM. If you put on an RSU the best way to remove it is to take a backup before you install it. VMFREM has a TEST option so I would recommend that you use it first. If all looks okay then run VMFREM without the TEST option. If something does not look right then you can always open a call to the support center. Pay attention to any messages. For example, if a build list was serviced with the PTF then you will need to do a VMFBLD and rerun VMFREM (should tell you this in a message). The default for VMFREM in UNAPPLY so if you want to also remove the parts associated with the PTF you need to use UNRECEIVE. Also note that the removed PTF(s) will be put in the exclude list, by default. So if you want to apply that PTF again you will have to manually remove it from the exclude list, such as HCPVM $EXCLIST. Be aware that a removed PTF may be a pre-req for another PTF. If so, then SERVICE or VMFAPPLY will fail, you can remove it from the exclude list and then restart SERVICE or VMAPPLY. Refer to the VMSES/E Introduction and Reference, Chapter 20, under the VMFREM EXEC for usage examples. Sincerely, Tami Zebrowski-Darrow z/VM VMSES/E Service and Support IBM Endicott
Re: Backout PTF(s) applied
Steve, CP does not use the 0190 and 0490 disks... those are the CMS system residence volumes. When you apply service to CP that goes in the CP nucleus (i.e. into the "CPLOAD MODULE" on the MAINT CF1 disk), then you only need to be sure that you have a backup copy of the CPLOAD MODULE on the CF1 disk. Before building service (perhaps with the SERVICE command), I manually link the MAINT CF1 disk R/W, and COPYFILE CPLOAD MODULE fm -1CPLOAD MODULE fm (OLDDATE REPLACE. IBM's PUT2PROD makes backups, too - but I prefer to have something that I know, and where I know it is every time. If the maintenance causes problems, you "just": SHUTDOWN REIPL MODULE -1CPLOAD (FYI, the filetype MUST be MODULE!) More detail: I actually keep several older copies of the CPLOAD MODULE, each time manually bumping their filename higher, as in -1CPLOAD, -2CPLOAD, -3CPLOAD, etc. in a manual version of a z/OS GDG dataset name. And I keep the a "@CPLOAD MODULE" which is the CPLOAD MODULE that was on the disk when we first brought up that z/VM version. Once the -1CPLOAD MODULE has been IPLed you can choose what you want to do about backing out the errant CP maintenance. That's why you pay IBM the S&S fee, let it be their problem (keeping jobs in the U.S. - maybe!). Mike Walter Aon Corporation The opinions expressed herein are mine alone, not my employer's.

Those folks actually understand SES well enough to tell you how to do it without screwing things up. If you don't know what all the options to VMFREM actually do, you stand an excellent chance of making your system unserviceable. That's why the support center gets the big bucks. They live for this stuff. -- db PS - yes, I would like some more koolaid, Mr. Leary.
Re: Backout PTF(s) applied
Thanks, Bill.
However, I don't think my question(s) were answered in that RED alert unless it
describes to me how best to backout ptfs applied. And from reviewing the
alert, I was not able to find that answer. And no, I do not have the PTF
applied that the RED alert indicated.
Thanks for your response. I will see if others here have feedback or
experiences here prior to contacting IBM.
Kind Regards,
Steve
