All of you on zEC12, running in parallel sysplex heads up. There are apparent bugs in CF code on these boxes that will cause CF failure in your sysplex. We experienced the CF failure. The first fix .008 has been out for a month, while the final 2 MCL fixes .009, .010 for this problem became available yesterday.
H09167.008<https://www-304.ibm.com/servers/resourcelink/svc03pok.nsf/vECDesc/H09167008?opendocument> 2013/04/24 25<https://www-304.ibm.com/servers/resourcelink/svc03pok.nsf/fWebECBundle?openform&bundle=D12B25> HIPER Coupling Facility abend with potential to cause sysplex wide impact if there isn't a backup Coupling Facility available. Coupling Facility image hangs and loads disabled wait PSW causing loss of connectivity for connected z/OS images. Depending on availability of backup Coupling Facility, this problem does have the potential for sysplex wide impact. While our sysplex survived on the remaining CF, we did lose all DB2 and MQ subsystems. I do not support either of those, so I do not have the details, other than to say the fixes required by MQ only just became available in the first part of this year, and there are configuration changes needed after that to avoid the interruption. I am not aware if this problem is also present in z196 or prior, so I would encourage you to look into it as well. There was at least one other installation that has also experienced this problem as recent as yesterday. _________________________________________________________________ Dave Jousma Assistant Vice President, Mainframe Engineering [email protected] 1830 East Paris, Grand Rapids, MI 49546 MD RSCB2H p 616.653.8429 f 616.653.2717 This e-mail transmission contains information that is confidential and may be privileged.
