We have z/OS 2.3 lpars running on z14_ZR1 machines without impact to availability in as little as 3 GB. We do of course see message:
IAR057D LESS THAN 8 GB OF REAL STORAGE IMPACTS SYSTEM AVAILABILITY - ADD STORAGE OR REPLY C TO CONTINUE Automation replies C. These are not production workload lpars though. We plan to install sufficient additional storage when it is time to replace the 14s, or if 2.4 (or some maintenance on 2.3) enforces the requirement. -----Original Message----- From: IBM Mainframe Discussion List <IBM-MAIN@LISTSERV.UA.EDU> On Behalf Of Allan Staller Sent: Thursday, December 05, 2019 8:57 AM To: IBM-MAIN@LISTSERV.UA.EDU Subject: [EXT] Re: A minimum of 8 GB of real memory is required to IPL I believe this is not currently a *requirement*. My recollection is that a warning message will be issued @IPL, but the IPL will continue. I have not heard of this being enforced at this time. -----Original Message----- From: IBM Mainframe Discussion List <IBM-MAIN@LISTSERV.UA.EDU> On Behalf Of Richards, Robert B. Sent: Thursday, December 5, 2019 8:51 AM To: IBM-MAIN@LISTSERV.UA.EDU Subject: A minimum of 8 GB of real memory is required to IPL * For z/OS V2R3 with the IBM z14(tm) (z14) server, a minimum of 8 GB of real memory is required to IPL. Does this statement only apply only to the z14 or all models *after* it? For example, the z14_ZR1 and the z15? ---------------------------------------------------------------------- For IBM-MAIN subscribe / signoff / archive access instructions, send email to lists...@listserv.ua.edu with the message: INFO IBM-MAIN ::DISCLAIMER:: ________________________________ The contents of this e-mail and any attachment(s) are confidential and intended for the named recipient(s) only.
