Terry, check the following: IOCDS definitions for the second LPAR. Was a new IOCDS created? SYSTEM CONFIG file for the PROD LPAR AUTOLOG1 Profile exec and all profile execs involved in bringing up the z/VM system in PROD LPAR Something must have been changed. I'm betting on the IOCDS.

After the VAL/DEV LPAR was brought up I started to logon and IPL the Linux guests. I had no problems on this LPAR. Now, after I IPL'ed the PROD LPAR I started to bring up the PROD Linux guests. This time when I logged on the guests the guest could not access any of the MDISKS assigned to it. I looked and found that all of the MDISKS were no longer attached to SYSTEM. I know these were attached on Friday because I brought all of the Linux guests up without a problem. It seems that they were detached during the IPL. On the VAL/DEV LPAR the MDISKS for the Linux guests stayed attached to SYSTEM after the IPL. Does anyone know why the MDISKS were detached from the SYSTEM on my PROD LPAR after the IPL? Thanks, Terry
