One REXX you might want to include on your system is http://www.mzelden.com/mvsfiles/iplinfo.txt
IPLINFO is a great tool that will show you all sorts of wonderful information. It can be run in batch or online It can let you know the HCD dataset, load parms and Parmlib Concatenations. All this can help when your IPL is not going as planned. All answers provided are good. I definitely would go through SYSLOG from the IPL and starting with message IEA093I scroll through the log to see how IEASYS was specified. Also in your specifications, you might want to include ,L as part of your parms where it applies For example to display your IEASYSxx members and details, you would use this coding: *---+----1----+----2----+----3----+----4----+----5----+----6----+----7-- SYSPARM (01,02,L) It is possible that maybe a delete of the good IEASYSxx occurred and it picked up the other version Was there an IEA101A SPECIFY SYSTEM PARAMETERS. And the response was 00 instead of 0b? The 0B in LOAD only says find a member called IEASYS0B. Could there be multiple versions of IEASYS0B in your PARMLIB Concatenation? What is on your PARMLIB statement in LOADxx If it contains multiple datasets, check each one for IEASYS0B Many things to look at Lizette -----Original Message----- From: IBM Mainframe Discussion List <IBM-MAIN@LISTSERV.UA.EDU> On Behalf Of Gadi Ben-Avi Sent: Saturday, October 3, 2020 11:55 AM To: IBM-MAIN@LISTSERV.UA.EDU Subject: IEASYS problem HI, I went into work this evening to IPL our production LPAR's When I IPL's one system, it used IEASYS00 instead of the system specific IEASYS0B. The LOAD member for the LPAR says SYSPARM 0B. The only thing that has changed recently is that we started using IEASYM for the first time ever. We specified IEASYM 00 in LOADxx and there is an IEASYM00 member in SYS1.PARMLIB that adds a static symbol. Could this be causing the problem? We are running z/OS v2.3 Gadi ---------------------------------------------------------------------- For IBM-MAIN subscribe / signoff / archive access instructions, send email to lists...@listserv.ua.edu with the message: INFO IBM-MAIN ---------------------------------------------------------------------- For IBM-MAIN subscribe / signoff / archive access instructions, send email to lists...@listserv.ua.edu with the message: INFO IBM-MAIN
