As far as I know, zHPF is disabled. However, I do not know how to confirm that.
We have 8 FICON paths to the DASD subsystem shared through switches to 2 z196 machines each having 8 FICON paths to the switches. Of the 8 paths, 4 have been offline from all 8 LPARs for a couple of months while we waited for IODF changes and physical cabling changes to move those 4 paths from old switches to newer switches. Last evening, I varied on the 4 paths that were moved to all 8 LPARs and verified that they were online to the DASD. I only spot checked the paths and not all 1800 volumes. After I confirmed that all 8 paths were online to the DASD, I took the other 4 paths offline. Shortly after that, the small subset of Linux guests began having problems. We only saw issues on about 20 of over 500 Linux guests. I am going to open a PMR and find out how to capture documentation to better understand what is happening. Thank you to all who suggested possible solutions.
