Alan, I made that device available to a VM in another LPAR on the same CEC, and there the IPL worked. Our 3 LPARs share the same Escon channels to an EMC box. Each LPAR only uses it's own set of DASD devices (the other devices are set offline according to SYSTEM CONFIG "OFFLINE_AT_IPL").
In the production LPAR I see msgs like this on the OPERATOR console: HCPMHT2153I DASD B03C I/O CANCELLED DUE TO A MISSING INTERRUPT They started appearing since the moment that I IPL'd another VM in another LPAR last weekend. I thought that maybe some devices were being used in both LPARs, but I checked, and that's not the case. Maybe EMC can find out more... Thanks, Geert. _____________________________ Geert Dieltiens Systeembeheerder Informatica J.

I still have no idea what could be causing this... There will be a MI message on the OPERATOR's console and an EREP record will have been cut. When you made the device available to your other VM system, was that system in another LPAR on the same CEC or a different CEC? (If a different CEC, then you have another hardware path.) Check your switch and storage controller consoles to see if they're unhappy for any reason.
