Ok, I've had time to research my "memory banks". This probably has nothing to do with the OPs original question but just for the record, there is a subtle difference between RESET NORMAL and RESET CLEAR that has to with more that just "clearing storage".
It has to do with the FDRPAS program. FDRPAS (and I would assume other products like TDMF) determine from any of the modern controllers (HDS, EMC or IBM) what LPARs have access to DASD volumes and then require that each LPAR that has access to participate in any volume movement being done by a program. If an LPAR is taken down, I think a RESET CLEAR is needed to inform the controller that the LPAR no longer has access. If that's not done, and you try to use FDRPAS from a different LPAR, FDRPAS will send nasty messages saying that not all accessing systems are participating on the move. At least that was my experience from a few years ago. Sometimes experience is more valuable than reading and quoting Redbooks. -- Guy Gardoit z/OS Systems Programming On Fri, Oct 2, 2009 at 11:03 AM, Scott Rowe <[email protected]> wrote: > Yes, it does. > > >>> "Ward, Mike S" <[email protected]> 10/2/2009 12:55 PM >>> > I thought reset did that and clear just cleared memory. > > -----Original Message----- > From: IBM Mainframe Discussion List [mailto:[email protected]] On > Behalf Of Guy Gardoit > Sent: Thursday, October 01, 2009 5:45 PM > To: [email protected] > Subject: Re: Deactivate LPAR > > SYSTEM RESET CLEAR will also clear any spurious I/O. > > On Thu, Oct 1, 2009 at 2:21 PM, Scott Rowe <[email protected]> wrote: > > > For his purpose I seriously doubt clearing storage would have any > effect > > whatsoever. > > > > >>> Guy Gardoit <[email protected]> 10/1/2009 5:05 PM >>> > > Make sure it is a RESET *CLEAR*. > > > > On Thu, Oct 1, 2009 at 8:02 AM, Donnelly, John P > <[email protected] > > >wrote: > > > > > We have a two LPAR environment; one PROD, one TEST. > > > We have been advised to DEACTIVATE the TEST PAR when not in use to > > provide > > > more process power to the PROD LPAR; at present we do a SYSTEM RESET > on > > the > > > TEST LPAR when not in use. > > > > > > Opinions? > > > > > > > > > > ---------------------------------------------------------------------- > > > For IBM-MAIN subscribe / signoff / archive access instructions, > > > send email to [email protected] with the message: GET IBM-MAIN > INFO > > > Search the archives at http://bama.ua.edu/archives/ibm-main.html > > > > > > > > > > > -- > > Guy Gardoit > > z/OS Systems Programming > > > > ---------------------------------------------------------------------- > > For IBM-MAIN subscribe / signoff / archive access instructions, > > send email to [email protected] with the message: GET IBM-MAIN INFO > > Search the archives at http://bama.ua.edu/archives/ibm-main.html > > > > > > > > CONFIDENTIALITY/EMAIL NOTICE: The material in this transmission > contains > > confidential and privileged information intended only for the > addressee.
