Then, 3:30 PM Monday, kaboom, disabled wait. IBM has determined we had a tight loop condition that triggered the processor being taken offline. We did get a MCW002 abend and dump. Dump analysis should lead IBM and us to fixing the loop and thus stopping it from happening again. Best theory so far is that zVM tried to restart following the MCW002 abend, couldn't find a console, thus the 1010 disabled wait. Thanks for all the suggestions! -----Original Message----- From: Burton, Randy Sent: Tuesday, June 14, 2011 9:47 AM To: 'IBMVM@LISTSERV.UARK.EDU' Subject: zVM crash I'm curious if this error rings a bell with any of you. We of course have an ETR open and are working with IBM. No hardware errors on the HMC, so we believe this was software and not hardware. Here's the last operator log message before the LPAR went into a disabled wait: HCPMPG9152E PROCESSOR 01 IS BEING VARIED OFFLINE BECAUSE IT IS NOT RESPONSIVE. Disabled wait PSW was: 00020000000000000000000000001010 HMC message was: Central processor (CP) 0 in partition VMD1, entered disabled wait state. Fortunately this was our development (test) zVM system, running a bunch of test zLinux guests. We're running zVM 6.1 on a z10. Of course we are nervous because what happens in test can happen in production. We IPLed and so far so good. Thanks in advance for any help/suggestions!
